Rich Harden will miss the 2012 season while he recovers from a shoulder operation, Peter Gammons of MLB Network reports on Twitter. Dr. James Andrews repaired a torn capsule in Harden's shoulder last week and the free agent right-hander aims to come back healthy in 2013.
Harden started 15 games for the 2011 Athletics, but he's no stranger to serious injuries, having spent much of the 2006 and 2007 seasons on the disabled list. The 30-year-old posted a 5.12 ERA with 9.9 K/9 and 3.4 BB/9 in 82 2/3 innings for the A's in 2011. He drew interest as a starter and as a reliever this offseason from teams such as the Rockies.
