Yankee relief pitcher David Robertson, has improved each year in the big leagues.

In 2011 Robertson has really shown what he is capable of doing. He is one of the top relievers in all of baseball with a 1.05 ERA and an eye-popping 55 strikeouts in only 34.1 innings pitched. If these numbers prove not to be a fluke, Robertson could very well be the successor to the great Mariano Rivera as the New York Yankee Closer. Robertson has hand signed this MLB baseball in blue ink on the sweet spot. A Steiner Sports Ceritifcate of Authenticity is included.
