Phil Maton Revisits Spin (and Comes to Terms With Cut)

Phil Maton can spin a baseball. His four-seamer averaged 2,563 rpm this season, and his signature curveball was an even-more-rotational 3,154. These weren’t new developments. The 30-year-old Houston Astros reliever has long been known for that attribute, with a July 2017 interview with the then-San Diego Padres rookie having served as its first detailed mention here at FanGraphs.
He’s also had a career-best year. In 68 regular-season appearances out of the Houston bullpen, Maton augmented his 4–3 record and one save with a 3.00 ERA, a 3.74 FIP, 74 strikeouts, and just 49 hits allowed in 66 innings. Moreover, October has once again been his friend. Thanks to a pair of scoreless outings in the ALDS, the righty boasts a 1.04 ERA over 16 career playoff appearances.
Maton revisited the importance of spin and discussed a meaningful change to the movement profile of his fastball when the Astros visited Fenway Park at the end of August.

David Laurila: Your spin rate was the primary topic when we first spoke six years ago. Now pure spin isn’t considered nearly as important. Do you agree?
Phil Maton: “I think that’s right. Over the years, organizations have figured out that it doesn’t tell the whole picture. There are guys with big breaking balls and hoppy heaters who don’t spin the ball particularly well. That’s where things like spin efficiencies come into play. We’ve identified guys where it’s the entry angle. There are so many different factors in what creates ‘a good pitch.’ Back in 2017, when the spin-rate phase was going on, everyone thought that was the answer. It’s much more complex than that.” Read the rest of this entry »
