His strikeout rate moves by 16.3 points between the two sides — he misses far more bats against left-handed batters. His xFIP barely moves (0.80), because his walk rate rises on the same side he strikes more out — which is exactly why the estimator alone hides this. A gap this size changes the read of a start.
