New York Yankees relief pitcher Joba Chamberlain has been released from hospital three days after dislocating his right ankle.Chamberlain will be in a non-weight bearing hard cast for six weeks after the open dislocation suffered while playing on a trampoline with his son. The team has not set a time table for his return."So far everything’s coming back extremely positive," Yankees GM Brian Cashman told reporters. "You guys know Joba -- obviously he’s been dealing with a lot, but he’s a healer. He gets hurt, but his healing process is really significant. So we’re counting on that in this case, too."Chamberlain posted a 2.83 ERA in limited action out of the bullpen in 2011. He had a 4.40 ERA with 77 strikeouts in 71 2-3 innings pitched in 2010.
