The Surprising Intrigue of Phil Maton
See if this story is familiar. A pitcher’s fastball appears so-so using traditional metrics but is revealed to possess off-the-chart spin rates. The pitcher then succeeds by locating up in the zone, taking advantage of that trait. At first glance, Astros reliever Phil Maton fits the bill. Here’s what he usually does with his four-seamer:
Maton’s fastball velocity is in the 20th percentile, but that doesn’t matter too much, because its spin rate is in the 92nd percentile. It’s what makes him big league viable — well, at least that’s the popular narrative. What isn’t as commonly known is this: Maton might have the league’s zaniest fastball. Zaniest? Trust me, this is an appropriate use of that word.
The anatomy of a fastball is complex, but let’s start with movement. Using our site’s pitch type splits, we see that Maton’s fastball has averaged 6.5 inches of ride (vertical movement) and 0.5 inches of run (horizontal movement) in 2021. The lack of vertical movement is strange, but hardly outlandish; plenty of major league fastballs are similarly deficient. What stands out is the absence of arm-side run. Consider Gerrit Cole’s fastball, the gold standard for righties, which features around seven inches of run and 10 inches of ride. There’s ample movement in both directions with an emphasis on the upward, bat-missing variety. Maton’s fastball is different; it’s as straight as an arrow and sinks like a stone. What gives?
