Tanner Houck on Learning and Developing His Splitter
Tanner Houck’s signature pitch is a sweeping slider. The 25-year-old Boston Red Sox right-hander has gone to it 35.5% of the time this season, and with good results. There is little question that the offering is the most lethal weapon in his arsenal. That said, it’s arguably not his most important pitch going forward — particularly if his future is in the starting rotation, and not out of the bullpen.
Bedeviled by an inability to master a conventional changeup, Houck began learning a split-finger fastball last year. The pitch remains something of a work-in-progress, yet he’s begun throwing it more frequently. Houck’s splitter usage is up to 7.5% on the season, a percentage that promises to rise if he can fine-tune it further. Four years after he was drafted 24th overall out of the University of Missouri, Houck is hoping that his newest pitch will take him to the next level.

At that time it was still 90-93 [mph]; it was essentially just a little bit worse of a two-seam. But I didn’t think anything of it. I was like, ‘This is literally day one of throwing this pitch, so it’s not a big deal.’ Then COVID happens, so I go home. Read the rest of this entry »
