The 2006 Detroit Tigers shocked baseball fans across the country with their remarkable resurgence, and a major factor in that resurgence was the success of pitcher Nate Robertson. A workhorse, Robertson threw a career-high 208.2 innings in 2006 while amassing a 13-13 record and a career-low ERA of 3.84. Nate Robertson has hand signed this official MLB baseball, which comes complete with a Steiner Sports Certificate of Authenticity.
