Blach had some unlucky results in 2019 on his changeup even with similar O-zone and Z-zone numbers to 2018. A .357 BABIP along with his wOBA being .090 higher than his xwOBA shows this was the case, and should bounceback in 2020.
Blach’s curveball had elite results in 2019, albeit in a small-sample, as it allowed just a .146 wOBA. Batters had a harder time making contact on it and ended up posting an 11.1% swinging-strike rate, the highest on his curveball for his career.
Blach’s fastball makes me go blegh. He walked more than he struckout with it, he gave up a 91.8% contact rate on it and it was -9.8 pVAL. Would be a wise investment to move away from it in the future.
A cutter/slider hybrid, the velocity jumped 4.8 mph in 2019, making me think it moved more towards a cutter. It showed less vertical movement in ’19 but did not get one swinging-strike in 45 pitches thrown. Did get an abundance of groundballs however.
Blach’s fastball is a classic innings eater’s delight. Made to induce ground balls, it did just that (53.4%), but unfortunately not enough. The pitch was hit as hard as it ever was in Blach’s career, though no massive change is evident in the numbers. Expect at least this production (3.8 pVal) with the opportunity for a good chunk more.
Blach’s changeup is quite a useful pitch. Thrown a quarter of the time, he gets a decent number of swinging strikes (12.7%) and nearly 80% of the batted balls were either grounders or infield fly balls. This pitch can be used at any time with decent effect. The definition of a workmanlike secondary.
This curveball is nothing spectacular and Blach’s non-reliance on the pitch says as much. However, it does have its place in Blach’s bland repertoire as a get-me-over, sequence-breaking looper. Batters did not offer at the pitch often; when they did they produced ground balls at an exceptional rate (71%). Blach should use caution with this pitch, though, as it doesn’t have the snap or velocity to stand up to a plus 20% usage rate.
Blach’s slider was a bit unlucky last year. The swing metrics didn’t change a whole lot from 2017, but the pitch carried a .557 BABIP. Now, that makes sense when you give up line drives at a 45.5% clip, but even then he was a bit unlucky. Expect this pitch to rebound and bite into Blach’s curveball usage.
