Joba Chamberlain 18×29 Signed Number Collage All season long in 2007 Yankees fans waited and waited and waited for the Bombers to call up Joba Chamberlain the 21-year-old pitching sensation who had been destroying the competition down on the farm. Finally on August 7 2007 the Yankees tapped Chamberlain to make his MLB debut. That night against the Blue Jays he struck out his first batter Ray Olmedo and pitched two perfect innings of relief. Chamberlain quickly emerged as a Yankee Stadium favorite and he looks likely to be a very big piece of the Yankees’ puzzle for years to come. Joba Chamberlain has hand signed this 18×29 framed number collage which includes a Steiner Sports Certificate of Authenticity.
