On Sunday, Boggs was ruled unavailable due to lower back tightness, something that plagued him on two different occasions in 2011. With treatment and time off, Boggs informed the medical staff on Tuesday that the discomfort had fully subsided.
That put Boggs in position to be called upon by manager Mike Matheny in Tuesday's series opener after starter Kyle Lohse wrapped up a seven-inning performance against the Astros. Boggs allowed three hits and one earned run, and could not close out the eighth.
"I felt OK," Boggs said on Wednesday. "Maybe I was protecting it a little more than I should have been. Later in the inning, I was letting it go pretty good. It's not an issue. I felt good today."
Boggs said he will continue to undergo treatment on his back in order to try and prevent any recurring issues.
