Herrera strained his right hamstring before the sixth inning of Tuesday's 7-6 loss at Marlins Park, and he was replaced by Marco Scutaro. Rockies manager Jim Tracy said following the game that he expected Herrera to be placed on the DL if the injury was projected to linger more than one or two days.
"It would've been extremely difficult for us to play shorthanded on our bench with some of the different things we have to do with certain lineups we have on the field, so we recalled D.J. and justifiably so," Tracy said.
The Rockies acquired LeMahieu, along with Tyler Colvin, from the Cubs in the offseason in the trade that sent Ian Stewart and Casey Weathers to Chicago. In 43 games for the Sky Sox, LeMahieu hit .315 with eight doubles, two triples, a home run and 26 RBIs. He also led Colorado Springs with 11 stolen bases this year.
"The work that he's done in Colorado Springs, from the Spring Training he had, he has had a terrific start to his season in the Pacific Coast League and deserves the opportunity to be here with us," Tracy said. "We're very, very familiar with him, we know all about him, we know what his capabilities are."
LeMahieu said he was informed of the callup Tuesday night and flew to Miami, arriving to join the team around 1 p.m. MT. He was available to play Wednesday night.
"I'm just here to do the little things, and when my name gets called, I'll be ready," LeMahieu said.
While LeMahieu said he was unsure of his role with the team, Tracy said he will be used as a utility infielder.
"He's played a lot of second, and quite frankly, the best place for him defensively is second base," Tracy said. "That's his best position and he plays it extremely well. That's not to say that he couldn't go over and play shortstop if we had to do so. ... He can definitely do that."
