Joba Chamberlain burst onto the scene in 2007 dominating in a setup relief role like few others ever had before. In 24 innings out of the bullpen in 2007 Chamberlain allowed only 1 earned run posting a 0.38 ERA. After some experimentation in the starting rotation in 2008 and 2009 the Yankees decided Jobas golden arm was best suited out of the bull pen in 2010 a role he has once again embraced. With experience and consistency Chamberlain has the necessary skill set to one day take over for Mariano Rivera as the Yankees closer.brbrJoba Chamberlain has hand signed this 8x10 photo of him pitching at the Original Yankee Stadium during his first career start.
