The White Sox have claimed left-hander Eric Surkamp off waivers from the Giants, according to Hank Schulman of the San Francisco Chronicle (on Twitter). Surkamp was designated for assignment by the Giants last week.

Surkamp split the season between Double-A and Triple-A as he recovered from 2012 Tommy John surgery, spending the bulk of his time in Triple-A Fresno. His work in the minor league was excellent, as he pitched to a 2.80 ERA with 7.4 K/9 and 2.4 BB/9 in 86 1/3 innings.

In his minor league career, Surkamp has a 2.84 ERA with 10.0 K/9 and 2.5 BB/9 in 484 2/3 innings. The former sixth-round pick made his big league debut for the Giants in 2011 and ranked among Baseball America's Top 30 Giants prospects from 2010-13.

Surkamp will provide the White Sox with more pitching depth that is essentially big-league ready. Chicago currently has Chris Sale, Jose Quintana and John Danks as locks for the rotation, with right-handers Erik Johnson, Andre Rienzo and the recently signed Felipe Paulino all as options for the back of the rotation. Surkamp figures to compete with those three for the fourth and fifth slots in the rotation following Hector Santiago's trade to the Angels.
