The Mariners have signed 37 year old righty Kevin Millwood to a minor league deal. Millwood pitched 54.1 innings in the big leagues last year, en route to a 3.55 xFIP in Colorado. Safeco Field figures to have a reverse effect on Millwood’s results that Coor’s Field had, as Millwood’s ERA was almost a half-run worse than his xFIP. Millwood also pitched 89.2 innings for minor league affiliates of the Red Sox and Yankees.
Millwood last pitched significant big league time in 2010, when he pitched his second straight 190+ inning season. He’s pitched in hitter’s parks since 2003, and has consistently out-processed his results. He may be someone like Javier Vasquez, who for whatever reason posts much better peripherals than results every year, or it may be a result of the parks he’s played in. Millwood’s righty-lefty splits are pretty even thanks to the running action on his fastball, and for essentially a no-risk deal, the Mariners have the opportunity to see–basically for free–if Millwood’s peripherals can swing his results back to a productive level.
