Those measures could include Crain's third outing of at least two innings this season or coming back for a hitter or two on short rest the day after those 2 2/3 innings.
"If it comes time to go in there, I'm always ready," said Crain, who said that he expected to throw two innings in relief of Gavin Floyd on Friday.
Crain ranks sixth among American League relievers with a .174 opponents average against. He also sits ninth with 11.30 strikeouts per nine innings, enhanced by Friday's four-strikeout effort.
After battling through right oblique, left oblique and right shoulder injuries starting back in Spring Training, Crain has reasserted himself as an important bullpen cog.
"The good news was it wasn't any bad injuries," Crain said. "You don't want to go through them, but if you're going to have an injury, you want it to be something that isn't serious and you can come back from.
"You've just got to make sure you're doing it the right way and you don't try to come back too early. If you're not playing right now when it's important, it's not good for the team."
