The Colorado Rockies placed left-hander Jeff Francis on the 15-day disabled list with a left groin strain and designated infielder Reid Brignac for assignment Thursday.
The Rockies also recalled infielder D.J. LeMahieu and right-hander Rob Scahill from Triple-A Colorado Springs.
Francis, 32, was hurt during Tuesday's win against the Cubs in Chicago. He is 2-3 with a 6.00 ERA and 31 strikeouts in eight starts this season.
LeMahieu batted .364 with one home run, 22 RBIs and 34 runs scored in 33 games for the Sky Sox this season. LeMahieu hit .297 with two home runs and 22 RBIs in 81 games for Colorado last season.
Scahill is in his second stint with the Rockies this season. He was recalled on April 21 and allowed one hit and struck out three in three innings against Atlanta on April 23.
