Pitch breaks Shin-Soo Choo's forearm in Rangers' 5-2 win over Athletics

ARLINGTON, Texas -- Texas Rangers designated hitter Shin-Soo Choo fractured his left forearm after getting hit by a pitch from Oakland Athletics left-hander Ross Detwiler in the fifth inning of the Rangers' 5-2 victory on Monday.

Choo was injured when he checked his swing on a pitch inside and immediately went to one knee holding the area near his left wrist.

He left after spending several minutes talking to an athletic trainer and was replaced by Nomar Mazara.

Following Mazara taking his base, Ian Desmond and Carlos Beltran singled to set up Adrian Beltre's decisive grand slam.

It was Beltre's 10th career grand slam and his 100th home run at Globe Life Park.

The news on Choo, who is headed to the disabled list for the fourth time this season, dampened Monday's win following consecutive shutout losses at home to Detroit.

The 34-year-old Choo has been limited to 45 games by calf and hamstring strains and lower back inflammation.

"He's such a key part of this ballclub, this organization,'' manager Jeff Banister said of his .250-hitting right fielder, who started this game as the designated hitter in his regular leadoff spot. "You feel terrible for him personally, and obviously it's a gut punch but one that we're going to be challenged with.''

Team spokesman John Blake said the injury was similar to one suffered in April by catcher Robinson Chirinos, who missed two months.

"Somebody you played with last year, somebody that's your friend, you hate for that pitch to get away from you,'' said Detwiler, who opened 2015 in the Texas rotation but was let go after starting 0-5. "It's not a good sign when you get pulled out of the game.''

The game also gave the American League West-leading Rangers 70 wins, the first AL team to do so this season.

The Rangers will recall outfielder Ryan Rua from Triple-A Round Rock to take Choo's spot on the roster. Mazara, a rookie who emerged the first time Choo got hurt this season, will see time in right.

The leadoff spot was mostly a mix of Jurickson Profar and Delino DeShields during Choo's third DL stint with the back injury.
