"Whether I come in in the second inning or the seventh inning, the goal is always the same: throw your pitch exactly where you want to throw it, and hope the results end up in your favor," Stammen said. "The only adjustment is that I don't have to be as stressed out for the first five innings, I get to relax a little bit because I'll probably be used a little later."
Stammen was a closer at the University of Dayton, but he began as a starter in the Nationals' organization. He had a 5.08 ERA in 38 starts before moving to the bullpen, where he has a 2.82 ERA.
"I saved one game last year. I pitched in almost every inning imaginable," Stammen said, "so any situation they put me in, I'll be ready to go."
