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 Joba's golden arm was best equipped to work out of the bullpen 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. This MLB baseball is hand signed by Chamberlain, on the sweet spot, in blue ink. It comes complete with a Steiner Sports Certificate of Authenticity.
