The Texas Rangers placed right-hander Frank Francisco on the 15-day disabled list before Saturday night's game against the Oakland Athletics.
Francisco left Friday night's 7-3 victory over the Athletics in the ninth inning when he aggravated a right rib-cage injury while walking the leadoff man.
Francisco was making his first appearance since last Saturday. He recently got a cortisone shot in his right armpit to deal with a strained muscle.
Left-hander Derek Holland was promoted from Triple-A Oklahoma City to take Francisco's place in the bullpen.
Francisco is 6-4 with a 3.76 ERA in 56 appearances for Texas this season, with a 2.13 ERA in 13 outings since the All-Star break.
Manager Ron Washington still expects Francisco to be part of his relief corps for the stretch drive. Francisco is eligible to be activated on Sept. 12.
"He's a huge piece," Washington said. "I've said it earlier and I'll say it again, we can't it done without Frankie."
Depending on matchups, Washington can use right-handers Darren O'Day and Alexi Ogando, and left-handers Darren Oliver and Matt Harrison in Francisco's setup role for closer Neftali Feliz.
This is Holland's third stint with the Rangers this season. He was scheduled to start for Oklahoma City on Saturday night before he was called up.
Holland is 2-2 with a 5.32 ERA in six games, five starts, for Texas this season.
