Baseball Nut is a free MLB app built for people who just want to follow the game — no ads, no gambling odds, no clutter. This guide walks through every feature so you can get the most out of it.

Scores

The scoreboard is your home screen. It shows every MLB game for the day with live scores, inning, count, base runners, outs, and team records — updated every 30 seconds automatically.

During live games, each card also shows the current pitcher, batter at the plate, and the ball-strike count — so you can follow the action without opening the full game view.

Use the arrows at the top to navigate between days, or tap the date to jump to any specific date. On mobile, you can also swipe left or right on the scoreboard to move between days. If there are live games, you'll see a green "LIVE" badge with a count of how many games are in progress.

Tap any game card to open the full game detail page with the box score, play-by-play, win probability, and top performers by NUT Score. At the bottom of every matchup card, you'll find a quick link to compare the two teams side by side.

On mobile, pull down from the top of the scoreboard to manually refresh scores. A floating scroll-to-top button also appears when you scroll down on longer pages.

Pinned at the top of the scoreboard is an auto-scrolling NUT tickerthat stays visible while you scroll through the day's games. Every value matches the stats and standings pages exactly — no separate calculations. Each section header is gold and clearly labels what you're looking at:

• Yesterday's Top NUT — single-game NUT leaders from the previous day's slate, with their stat line
• Top Hitting NUT — players — top 5 hitters by season NUT
• Top Pitching NUT — players — top 5 pitchers by season NUT
• Top Hitting NUT — teams — top 5 teams by lineup NUT
• Top Pitching NUT — teams — top 5 teams by staff NUT
• Top Overall NUT — teams — top 5 teams by combined hitting + pitching NUT
• Notable Team Streaks — longest active win/loss runs, wins listed first then losses, each with a 10-game W/L bar showing the streak in context (full-opacity dots are the active streak, dimmed dots are older games)

Below the ticker is a mode-aware modulethat changes throughout the day depending on the slate's state:

Before First Pitch — Marquee Matchup & More Matchups

In the morning hours before any games start, you'll see a featured Marquee Matchup card highlighting the most compelling game on the slate, ranked by a single composite score we call matchup NUT:

matchup NUT = 1.5 × (away SP + home SP) + (away lineup + home lineup)

The top card reads MARQUEE MATCHUP when at least one of the day's probable starters has a Star-tier season NUT (≥1.5 for pitchers); on slates without an ace on the mound, it shows TOP MATCHUP instead — same ranking, more honest billing.

The marquee card shows each probable starter's season NUT, each lineup's aggregate season NUT, and the breakdown so the math is legible. Tap the lineup section to expand each team's top five hitters by season NUT — with name, position, OPS, and NUT per player. Below the marquee is a collapsible More Matchups list — every other game on the day, ranked by the same matchup NUT. Tap to expand.

During Live Games — Live NUT Leaderboard

The moment any game tips off, the marquee board is replaced by a Live NUT Leaderboardshowing the top 5 single-game NUT performances happening right now across all in-progress games. It refreshes every 30 seconds, with each row showing player, team, current stat line, opponent, and the inning the game is in. A small "updated Xs ago" indicator ticks every 5 seconds.

After All Games Final — Standout Performances

Once every game on the date is final (or terminal-special-status like postponed), the live leaderboard is replaced by ★ Standout Performances— a recap card listing the day's top 5 single-game NUT scores. Each row links straight to that player's profile.

Each final game card also shows each team's NUTdirectly under its score — a quick read on how impactful each side was at the plate and on the mound. Add the two together to get the game's Total NUT.

Between the two team scores, every live and final card displays an inning bar chart— away team runs above the baseline, home team runs below, one column per inning. It's an at-a-glance read on how the scoring unfolded: a single tall column means a big inning, alternating bars mean a back-and-forth game. On live cards, the team win probability sits right beneath the chart so you can see momentum without opening the game.

Every final game card picks up a narrative tag in the status row to summarize the story of the game:

• PERFECT GAME — pitcher faced 27 batters, retired all 27
• NO-HITTER — winning team allowed zero hits
• WALK-OFF — home team won by scoring the go-ahead run in their last at-bat
• MARATHON — game went 12 or more innings
• EXTRAS — game went 10 or 11 innings
• COMEBACK — winner trailed by 4 or more runs at some point
• BLOWOUT — winning margin of 7 or more runs
• SHUTOUT — the losing team didn't score
• PITCHERS' DUEL — winner scored 3 or fewer runs and the teams combined for 12 or fewer hits
• SLUGFEST — combined 18 or more runs
• BIG INNING — the winning team scored 4 or more in a single frame
• MULTI-HR — a single hitter went deep 2 or more times
• SEESAW — three or more lead changes
• LATE RALLY — winner took the final lead in the 7th inning or later
• NAIL-BITER — final margin of 1 or 2 runs
• WIRE-TO-WIRE — winner scored first and never trailed
• RALLY — winner trailed at some point but didn't qualify as a full COMEBACK
• TIGHT FINISH — a save was credited and the margin was 3 runs or fewer
• STEADY WIN — fallback when no other tag applies

Each game gets the most specific tag that fits — a walk-off comeback shows WALK-OFF rather than COMEBACK because the dramatic finish is the bigger story.

Favorite Teams

Go to Standings and tap the star next to any team name to favorite them. You can also favorite a team from their team page. You can favorite multiple teams.

Your favorite teams automatically pin to the top of the scoreboard with a highlighted border, so you never have to scroll to find their games. If a favorite team is playing live, their card gets an extra-prominent outline.

Standings & Team Pages

The Standings pageshows every MLB division with win-loss records, games back, winning percentage, NUT team rankings, and expected wins-losses (xW-L) based on Pythagorean expectation. The xW-L column shows whether a team is winning more or fewer games than their run differential suggests — green means they're overperforming (winning more than expected), red means they're underperforming (winning fewer than expected). Each team also shows a magic number (M#) to clinch the division and an elimination number (E#) — both update as the season plays out. Wild card standings are visible beneath each division tab so you can track the full playoff picture from one screen. Toggle between AL, NL, or MLB to see both leagues ranked together.

Tap any team to open their full team page. The bio card up top shows the team's record, division standing, championships, and a Season NUT badge with their tier (Nutty / Star / Solid / Average / Below Avg) and Hit/Pitch breakdown. A live game line tells you when the team is playing right now (or what their last game was). Below the badge, a single meta-line shows Win %, Run Differential, current streak, and Last 10. Below the bio: five tabs of deep analysis:

Season

Team Overview gives you a quick strength, weakness, and outlook for the team. Below that, Quick Stats show key batting and pitching numbers with All/Last 7D/Last 14D/Last 30D filters and the team's aggregate NUT score — so you can see if a team is hot right now vs. their season average. Actual vs Expected compares the team's real record to their Pythagorean record (expected wins based on runs scored vs. allowed) — if they're overperforming, they may be due for regression. Percentile Rankings show where the team ranks among all 30 MLB teams for every key stat, with color-coded bars so you can spot strengths and weaknesses at a glance. Hitting is grouped into five sections — Value (OPS, NUT, wOBA, xwOBA), Production (AVG, xBA, OBP, SLG, xSLG, ISO, HR, R), Discipline (BB%, K%, SwStr%, Contact%), Approach (Swing%, P/PA), and Speed (SB, Sprint Speed). Pitching is grouped into three sections — Value (ERA, NUT, ERA-NUT, FIP, xFIP), Run Prevention (WHIP, BAA, HR/9, LOB%), and Stuff (K%, K/9, Whiff%, BB%, BB/9, K-BB%, Strike%). Trending Playershighlights the team's top NUT performers over the last 7 days.

Trends

Rolling 10-Game NUT is a line chart with green/red area fills showing the team's performance trajectory — when the line is above zero and green, the team is producing above-average NUT; red means below average. Toggle between total, hitting, and pitching. NUT by Month shows centered bars for each month — green bars extend right for positive months, red bars extend left for negative ones. Below that, Year by Year gives the full season-over-season stats table with a NUT Trend sparkline showing how the team has performed historically.

Splits

See how the team performs in different situations — Home vs. Away, Wins vs. Losses, Day vs. Night, and by month. Every split includes a NUT column so you can see where the team generates the most (or least) value. The NUT comparison cards at the top give you an instant visual of the biggest splits. Plate Appearance Breakdown shows the team's batted ball distribution with K%, BB%, BABIP, and GO/AO ratio. The vs Opponenttable shows the team's record, run differential, and key stats against every team they've faced.

Roster

The Depth Chart shows the active roster grouped by position — starters, relievers, catchers, infielders, outfielders, DH — with key stats for each player. Injured list players are grouped by IL type. Below that, Pitch Arsenalbreaks down every pitcher's pitch mix with usage percentages, average velocity, and color-coded bars — so you can see at a glance that a starter throws 40% fastballs at 96 mph and 25% sliders at 87 mph. Starters and bullpen arms are shown separately.

Schedule

A monthly calendar heatmap shows game NUT scores color-coded by quality, with W/L bars at the bottom of each cell. Below the calendar, games are grouped by series with opponent records, scores, and probable pitchers for upcoming games.

Stats

The Stats page is a full MLB leaderboard. You can browse leaders for every major statistical category:

• Hitting: NUT, R, H, 2B, 3B, HR, RBI, BB, SO, SB, AVG, OBP, SLG
• Pitching: NUT, W, L, ERA, SV, IP, SO, BB, WHIP, Holds, Blown Saves

Toggle between Players and Teams, Hitting and Pitching. Use the search bar to find any player by name. For deeper filtering, tap the Filters button to narrow by date range (Season, Last 7D, 14D, 30D, or Custom), league (AL/NL), division (East, Central, West), position, or pitcher role (SP/RP). Active filters show as tags next to the button, and you can clear them all with one tap.

A results count above the leaderboard updates as you filter — so you always know how many players or teams match your current view.

The NUT leaderboard shows every player with at least 1 plate appearance or 1 inning pitched, so you can watch NUT accumulate from the very first game of the season.

Player Profiles

Tap any player name anywhere in the app to open their full profile. The bio card up top shows their jersey number, position and team, plus a Career NUT badge with their tier (Nutty / Star / Solid / Average / Below Avg) and total. A live game line tells you when the player's team is playing right now (or what their last game was). A meta-line below shows handedness, height/weight, birthplace, and how they entered pro ball. Below the bio: five tabs of analysis:

Season

Quick Stats show the player's key numbers with All/Last 7D/Last 14D/Last 30D filters and a large NUT badge — use this to check if a player is hot right now vs. their season baseline. Below the stats, On Pace For projects the player's counting stats to a full 162-game season (or 200 IP for starting pitchers, 70 IP for relievers) — so you can see where they're tracking for HR, RBI, SB, and NUT. Actual vs Expected compares the player's real NUT to their expected NUT (xNUT for hitters uses quality of contact; ERA NUT for pitchers uses fielding-independent stats). If xNUT is higher, the player is underperforming their batted-ball quality — the verdict reads "Underperforming expected stats." If it's lower, they've been overperforming — "Outperforming expected stats." When they match, it reads "Matching expected stats." Percentile Rankings show where the player ranks among all MLB players in key categories with color-coded bars — gold for 90th+ percentile, green for 60th+, gray for average, red for below 40th.

Trends

Cumulative NUT shows total NUT accumulation across the season as a line chart with area fill — each dot is a game, colored green (positive NUT) or red (negative). The 7-Game Rolling NUT chart uses green/red area fills split at the zero line to show recent trajectory — when the line is in the green zone, the player is contributing above average. NUT by Month shows centered bars so you can see which months the player carried the team. The Game Log table lists every game with opponent, stat line, and NUT — filter by All, Last 7D, Last 14D, or Last 30D.

Splits

Breakdowns for vs Left/Right handed pitchers, Home/Away, Win/Loss, Day/Night, by pitch count, runner situations, leverage (high/medium/low), monthly, and career. Every split shows full stat lines — for hitters: PA, AVG, OBP, SLG, OPS, HR, BB, SO; for pitchers: IP, ERA, WHIP, AVG, SO, BB, HR. Platoon splits are essential for evaluating lineup matchups.

Zones

Strike Zone Heatmap shows SLG by zone in a 5x5 grid — red zones are where the hitter crushes, blue zones are where they struggle. Pitch Locations plots every pitch as a dot, color-coded by outcome (called strike, whiff, ball, foul, in play), with inside/outside oriented to the batter's handedness. Below it, an at-a-glance usage donut pairs with a per-pitch breakdown table: on pitcher pages, Pitch Arsenal shows pitch type, usage %, average velocity, total break, and spin rate; on hitter pages, Pitch Mix Faced shows the same usage donut plus pitch type, usage %, and average velocity of pitches thrown at him (break and spin only apply to pitcher-side data). The Spray Chart maps hit locations on a diamond view. Exit Velo vs Launch Angle is a scatter plot showing batted ball quality — the barrel zone (high exit velo + optimal launch angle) is highlighted, and dots in that zone are home runs waiting to happen.

Career

Year by Year shows the full career stats table with NUT for every season — league-leading stats are highlighted in amber badges. Milestone Watch tracks how close the player is to career milestones (3,000 hits, 500 home runs, etc.) with progress bars. Career NUT Trend sparkline and NUT by Season centered bar chart show how the player's production has evolved over their career. NUT Breakdown is a donut chart showing what drives the player's NUT — for hitters: power, contact, and discipline; for pitchers: strikeout ability, HR prevention, and walk avoidance. Awards lists every career honor grouped by year.

Every NUT score is color-coded so you can tell at a glance how a player is performing:

The NUT Score

NUT (Net Unbiased Total) is Baseball Nut's signature metric — the number the box score doesn't want you to see. It measures how many wins a player adds or costs their team, built on hitting (wOBA) and pitching (FIP). One number, calculated the same way every time.

A NUT of 0 is league average. Positive means the player is helping their team win. Negative means the opposite. The higher the number, the bigger the impact.

You'll see NUT everywhere in the app — on game cards, player profiles, standings, the stats leaderboard, Trending Players, and Player Tracker. Every NUT score is color-coded by tier so you can instantly tell if a player is having an elite season or a rough one.

Tools

The Tools tab in the bottom navigation is your hub for all of Baseball Nut's analysis features — Transactions, Trending Players, Player Tracker, Stat Comparison, and Trade Analyzer. Each one is described in detail below.

Trending Players

The Trending Players page ranks the hottest players over the last 7 days by NUT accumulation. Filter between All, Hitters, and Pitchers.

Each player shows their NUT-relevant stats — hits, home runs, walks, and HBP for hitters; strikeouts, walks, and home runs allowed for pitchers. You'll also see their at-bats or innings pitched for context, and fire emojis that scale with their NUT output.

Tap the + button next to any player to add them to your Player Tracker.

Player Tracker

The Player Tracker is your personal watchlist. Add up to 40 players and monitor their season stats, NUT scores, and current status (active, injured, suspended, free agent) all in one place.

To add a player, tap the + button on the Stats page, Trending Players, or any player profile. Two-way players (like Shohei Ohtani) are tracked as both a hitter and pitcher automatically.

Players are sorted by NUT score by default. Filter between All, Hitters, and Pitchers if you have both on your list.

Switch the time window with the Season / Last 7D / Last 14D / Last 30D pills at the top — stats and NUT recompute over the selected window, so your hottest players over the last week or month rise to the top automatically.

Tap the pencil icon next to any player to add a personal note (up to 280 characters) — handy for things like "hot bat," "watch K rate," or "IL stash." Notes save with the rest of your watchlist.

No account required. Your watchlist saves locally on your device.

Stat Comparison

The comparison toollets you pick any two MLB players and see their stats side-by-side. Every category is compared head-to-head with the leader highlighted in bold, and you'll see each player's NUT Score at the top. Use the year dropdown to compare specific seasons or career totals — you can even compare Judge's 2022 MVP season against Ohtani's 2023. Career comparisons include awards like World Series titles, MVPs, All-Star selections, and more. Expand the Head-to-Head card for a written breakdown of how the two players stack up. Share any comparison with the Share button.

Fantasy Trade Analyzer

The trade analyzerhelps you evaluate fantasy baseball trades. Add up to 5 players to each side and the tool projects rest-of-season NUT for each player to show which team wins the deal. Projections blend current season pace with last year's track record — leaning on history early in the year and shifting toward current stats as the season goes on. Both hitters and pitchers are measured on the same scale (wins), so you can compare across positions.

Daily NUT Check

NUT Checkis a daily trivia game built into the app. You're shown two MLB players and one career stat — pick who has the higher number. Ten rounds per day, new puzzle every morning. The daily challenge uses 2000s–2020s players, but practice mode lets you go all the way back to the 1900s.

Baseball Stats Glossary

Not sure what OPS, wOBA, or FIP mean? The Glossaryexplains every baseball stat in plain English — with formulas, benchmarks, and how each stat connects to NUT Score. 25 stats have their own deep-dive pages with benchmarks and related stats.
