Tom Milone and the Scourge of a Weak Four-seamer
While velocity isn’t everything when it comes to being a successful major league starting pitcher, it’s surely a large part of the story. Starting pitchers who have a higher velocity — particularly on their four-seam fastballs — tend to have higher strikeout rates and induce weaker contact from opposing batters. And pitchers who can limit balls in play through strikeouts, tend to have lower earned run averages. Of course, not every major-league starter can sport a blazing fastball. A number of starting pitchers have not only survived, but they’ve thrived during seasons where their velocity was significantly lower than league-average.
Which brings us to the case of Oakland Athletics left-hander, Tom Milone. After starting five games as a 24-year-old for the Nationals last season, Milone was shipped out as part of the deal that sent Oakland’s Gio Gonzalez to Washington. Milone, now 25, has worked his way into the Athletics’ rotation this season — this despite an underwhelming fastball. Generally, Milone’s four-seam fastball (a pitch he throws about 54% of the time) has averaged less than 88 mph. For some perspective: In the past three seasons, major-league starters have averaged 91 mph on the four-seamer.
What are the odds that Milone can perform above league average this season, given the lack of zip on his fastball? To answer this, I looked at some similar pitchers who have played during the Pitch FX era (2007-present). Read the rest of this entry »
