The Yankees claimed pitcher Jeff Marquez off waivers from the White Sox, MLBTR has learned. The 26-year-old righty had been designated for assignment by Chicago on Sunday. The move will require the Yankees to open up a spot on the 40-man roster; Marquez will be in uniform for tonight's game against the Red Sox.
Marquez was drafted 41st overall by the Yankees in 2004 and was later traded to the White Sox as part of the Nick Swisher deal in November of 2008. This year in nine Triple-A starts he posted a 3.97 ERA, 6.8 K/9, 2.8 BB/9, and 0.9 HR/9 in 47 2/3 innings.
