The Yankees claimed David Herndon off of waivers from Toronto, according to the team's website. The Blue Jays designated the right-hander for assignment one week ago after claiming him from Philadelphia on October 23rd.
The 27-year-old underwent season-ending Tommy John surgery in June, which means he won't be ready to return until midway through the 2013 season. Herndon was a key contributor for the Phillies from 2010-11, when he posted a 3.79 ERA with 5.6 K/9 and 3.4 BB/9 over the course of 92 games. He appeared in five games for the Phillies this April before being placed on the disabled list.
