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. Using a silver marker, Joba Chamberlain has hand signed this great 8x10 horizontal photograph of him pitching at Yankee Stadium during the 2007 season. Chamberlain has affixed his signature directly beneath the words "It's Joba Time!" A Steiner Sports Certificate of Authenticity is included.
