The Texas Rangers put Wyatt Langford on the 10-day injured list Monday and expect the rookie outfielder to miss three to four weeks after suffering a Grade 1 right hamstring strain.
Langford left Saturday night's game after struggling to run to first base, and an MRI revealed the extent of the injury. His move to the IL was made before the Rangers opened a four-game series in Oakland and was retroactive to Sunday, the day after Langford exited the game at Kansas City.
Rangers manager Bruce Bochy said Langford had dealt with the injury in the past, but "it just got to the point where he felt like he had to say something."
"You hate to see it," Bochy said. "It's always tough. Looking back, I wish I'd have known anything was there as far as the hamstring, which we didn't know."
Texas recalled infielder Jonathan Ornelas from Triple-A Round Rock, where in 24 starts at shortstop this season he has hit .278 with two homers and 11 RBI. He made his big league debut last season, playing for the Rangers in eight game
"He's doing a nice job down there," Bochy said. "We've talked about him earlier as far as call-ups. He gives us versatility, with the ability to play anywhere in the infield, go play the outfield if needed. He can pinch-run, go in late in the ballgame, do some things for you. We needed another position player when Langford went down, so it just made sense to bring him up."
Bochy told reporters on Sunday that Nathan Eovaldi is set to visit a specialist in New York for evaluation on the right groin strain that landed the right-hander on the 15-day injured list Friday.
Langford, 22, is hitting .224 with one home run -- which was an inside-the-park homer -- and 11 RBIs in 31 games.
He was selected by Texas with the No. 4 pick in last year's draft out of the University of Florida. He broke camp with the Rangers after hitting .365 with six homers in 21 games during spring training.
Eovaldi, the Rangers' Opening Day starter this season, exited with the groin injury in the sixth inning against the Washington Nationals on Thursday and had an MRI on Friday.
