Doug Fister pitched in a Mariners rotation that included Felix Hernandez and Cliff Lee. He pitched in a Tigers rotation that boasted Justin Verlander and Max Scherzer. And he thinks his current rotation in Washington — featuring Stephen Strasburg, Gio Gonzalez and Jordan Zimmermann — might just top them all. "I've certainly been blessed to be a part of some teams and rotations I've been with," Fister said Saturday at NatsFest. "I think here we are just as good, if not better." Acquired from Detroit earlier this winter to bolster what already was one of baseball's most-talented rotations, Fister is comfortable slotting in as the No. 4 starter when he can point to three elite pitchers ahead of him on the depth chart. And this is nothing new for the right-hander, whose entire career has been spent in the shadows of bigger-name teammates. In Seattle, Fister pitched behind Hernandez for three seasons and also Lee for part of 2011. Traded to the Tigers that summer, he joined a rotation that already touted Verlander as ace as well as a burgeoning young talent in Scherzer (now the reigning AL Cy Young Award winner). Fister, who turns 30 next month, was particularly excited to meet several of his new rotation mates this weekend.
