Regression watch
Running hot. Expect some cooling.
Kiner-Falefa’s wOBA sits at 0.317, but the quality of contact underneath says it should be 0.297 — a gap of 0.019, -0.6 standard deviations from the MLB norm over 202 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
