Thread: The sinker is a dying pitch in the MLB. 😢

Still, Tanner Houck and his sinker were some of the few bright spots during a depressing Red Sox season.

Albeit a limited sample size, hitters had a .161 wOBA and a .122 xBA on the pitch.

What makes his sinker different?👇
The pitch has good movement (15.7 in.➡️, 31.8 in. ⬇️ w/ grav.), but what makes the pitch special is the the way he achieves this break.

The movement on most pitches is caused by the Magnus Effect, but Houck's sinker gets more non-Magnus movement than any SI in the league.
The pitch has a 1:31 Spin Direction, but b/c of the seam orientation and gyro component, it moves like it has a 2:43.

When Houck throws on a Rapsodo, his actual pitch movement isn’t correctly calculated— b/c it only calculates Magnus. ( @BaseballCloudUS)
Takeaways:

1. Have coaches that understand limitations of pitch tracking tech (or pay @NotRealCertain to explain).

2. ⬆️ the inferred movement could actually ⬇️ the pitch's actual mvmt/effectiveness.

3. Your 👀 and the hitter can be the best indicators of a pitch's quality.
