ARLINGTON -- Rangers reliever Frank Francisco made his first appearance in six days, but it did not last long.
Francisco faced just two batters on Friday night during the Rangers' 7-3 win over the A's before being pulled from the game because of a strained ribcage muscle, and he will have an MRI on Saturday. It's the same muscle that has bothered him all week.
"I felt it pull again," Francisco said. "I just decided to stop. I didn't want to make it worse."
Francisco needed one pitch to retire the last batter of the eighth inning. He got Kevin Kouzmanoff on a fly to left but then, trying to protect a 7-3 lead, he walked Jeff Larish to start the ninth.
Rangers manager Ron Washington said the club will know more after the MRI on Saturday. There is a possibility Francisco could go on the disabled list. By doing that, the Rangers could call up another pitcher from Triple-A -- Derek Holland or Pedro Strop -- who would then be eligible for the postseason.
To be eligible for the postseason roster, a player either has to be on the active roster or the disabled list on Aug. 31.
Francisco had pitched just twice in the Rangers' past 14 games while dealing with the strained muscle in the right ribcage. He had a cortisone shot earlier this week and this was his first time on the mound since getting injected on Monday.
