Manager Davey Johnson felt Detwiler could have gone another inning because of a low pitch count, but needed relievers Ryan Perry and Henry Rodriguez to get some work in the game.
It will be interesting what role Detwiler will play on the team. He is out of options and most likely will start the season as a long reliever. Detwiler was in that role briefly last season before being put in the rotation.
"It's all pitching once you get down to it," Detwiler said. "If I'm in the bullpen, I have to rely on those guys to teach me a routine ... find something that works for me."
