Holland out at least 2 months with shoulder strain

Lefty pitched one inning in loss to Astros; Rua expected to hit DL with sprained ankle

Holland out at least 2 months with shoulder strain

ARLINGTON -- Rangers pitcher Derek Holland will be out at least two months, and possibly more with a subscapularis strain in his left shoulder. Texas is also expecting Ryan Rua to go on the disabled list with a sprained right ankle.

Those were the major blows to the Rangers during their home opener and a 5-1 loss to the Astros on Friday afternoon.

Holland is not expected to resume throwing for at least another four weeks. After that, it should be another 1-2 months of rebuilding arm strength before he is able to pitch in the Majors again.

"I'm beat up about this," Holland said. "I felt it on the last warmup pitch and I just wanted to make sure I got through the inning. Everything was great in the 'pen. I joke around about it now with [catcher Robinson] Chirinos. I was spotting up, everything was good, ball was coming out great and then to come out here and throw the first pitch and have it go down the drain like that, it crushes you."

The Rangers were concerned immediately when they saw Holland's velocity below 90 miles per hour. At one point, third baseman Adrian Beltre came over to check on him, along with Chirinos.

"I was hoping the radar gun was off or he would get loose," general manager Jon Daniels said.

"It looked like he was throwing changeups," shortstop Elvis Andrus said. "That concerned me, especially since in Spring Training he was throwing fine."

The Rangers had Anthony Bass warming up by the time the inning was over. He took over in the second inning.

Bass allowed just one run in five innings of relief, and he could be a candidate to replace Holland in the rotation. Texas could also go with Anthony Ranaudo or Alex Gonzalez from Triple-A Round Rock. Veteran left-hander Wandy Rodriguez is another option. He was signed to a Minor League contract earlier this week just for this contingency.

"We haven't made any decisions on who it will be," Daniels said.

Banister on Rangers' injuries

Rua is expected to be examined further on Saturday, but Daniels admitted that the DL is likely. Rua left the clubhouse after the game with his right foot in a boot.

"That's definitely not how I expected my home opener in Texas to go," Rua said. "We'll see how it goes."

Rua said he started feeling the ankle in the early innings. The Rangers were concerned after watching Rua run the bases in the fourth. Those concerns were heightened when he chased down a double in fifth inning.

"It wasn't his normal gait," manager Jeff Banister said.

The Rangers have outfielders Carlos Peguero, Jared Hoying and Michael Choice at Round Rock if they elect to make a move.

Right fielder Shin-Soo Choo came out of the game after two innings because of spasms in his upper back. But he responded to treatment during the game, and he is hopeful he will be able to play on Saturday.
