The Blue Jays announced that they claimed right-hander Jesse Chavez off of waivers from the Royals (Twitter link). The Royals designated Chavez for assignment ten days ago when they claimed Aaron Laffey off of waivers.
The Royals acquired Chavez from the Braves in the summer 2010 trade that sent Kyle Farnsworth and Rick Ankiel to Atlanta. The right-hander had two stints with this year's Royals team, but spent most of the season at Triple-A Omaha, where he posted a 3.75 ERA with 8.4 K/9 and 2.5 BB/9 in 57 2/3 innings of relief work. He provided the Pirates with a solid season of relief in 2009 and hasn't been able to replicate that success at the Major League level since.
