Diagnosing Rafael Soriano’s Woes
To say that Rafael Soriano has struggled so far this season would be akin to saying Babe Ruth was a decent ballplayer: you’d technically be right, but off by multiple factors of ten. Soriano has struggled mightily since making his Yankee debut, allowing at least one baserunner in nine of his ten appearances, and posting an “Ouch!” inducing 7.84 ERA and 5.55 FIP. He has three meltdowns already this season (only had four total in 2010), and he’s blown two Yankee leads: once on April 5th against the Twins and once last night against the White Sox. Last night was particularly painful, as Soriano plunked Carlos Quentin with a slider and then grooved a fastball down the heart of the plate to Paul Konerko. I don’t think I need to tell you where that pitch ended up.
Since it’s so early in the season, it’s easy to write off these struggles as relatively unimportant; odds are, this is just a slump and Soriano will be his normal, dominant self for the rest of the year. Soriano has only thrown 10 innings this year, so it’s way too early to begin putting credence in his ERA, FIP, or xFIP. But while that may be true, I don’t like leaving analyses at this level; I want to know why Soriano is slumping now. Is this simply a matter of bad luck? Has he changed his pitching approach? Is he struggling with any of his pitches?
