SB (Stolen Bases)
A stolen base advances a runner ninety feet at the cost of an out if it fails. The break-even point is roughly a 75 percent success rate — below that, the caught stealings cost more runs than the steals create.
Larger bases and pickoff limits have pushed stolen base totals up across the league in recent years, and success rates with them. A 30-steal season means less than it did a decade ago; the success rate is now the more informative half of the line.
NUT deliberately leaves baserunning out. It is a hitting-and-pitching measure, which keeps it consistent and free of the modeling disagreements that make two versions of WAR differ by a full win. For a player whose value is mostly legs, read NUT alongside the steal total rather than expecting one to contain the other.
What is a good SB?
Stolen bases are not in NUT. NUT measures hitting and pitching only, so a burner’s baserunning value sits outside the number by design.
