ANAHEIM -- A day after Garrett Richards left his start against the Rangers after just two-thirds of an inning, the Angels placed him on the 15-day disabled list with a right groin strain.
The Angels also optioned infielder Andrew Romine to Triple-A Salt Lake and called up pitchers Trevor Bell and Horacio Ramirez. The Angels were trying to reinforce a bullpen that was needed for 8 1/3 innings on Monday night after Richards left the game. The Angels also had rookie Tyler Chatwood on the mound on Tuesday.
"Trevor is here to give us a little bit of length," Angels manager Mike Scioscia said. "We went through almost nine innings in our bullpen. If we need length, he can give it to us. With him and Horacio, we need them just in case Tyler struggles."
Ramirez was 3-1 with a 3.40 ERA in 40 appearances (one start) for the Bees and had an 11.25 ERA in five games for the Angels earlier this season. He has pitched in 162 Major League games, including 105 starts, from 2003-11.
Bell was 2-3 with a 5.97 ERA in seven starts and one relief appearance at Salt Lake and had a 3.24 ERA in 15 relief appearances for the Angels earlier this season. He started the season at Salt Lake, was called up on April 22 and optioned back on July 21.
Richards was making his second Major League start when he strained his muscle in the first inning on Monday night against the Rangers.
"It is just something that could happen to anyone," Richards said. "I am disappointed. I didn't have any discomfort last night while I was sleeping or anything. I woke up this morning and it feels a lot better than it did yesterday, which is good. I'm able to walk around with no discomfort. It is just a little sore."
The Angels are still waiting on some tests to come back before they know the full extent of the injury.
"But an injury like that is going to be a couple of weeks to get it calmed down and then testing it again," Scioscia said.
