ARLINGTON -- The Rangers will find out as early as Sunday if they have to put pitcher Kevin Millwood on the disabled list because of a strained right groin muscle.
It was something the Rangers talked about after a 6-4 victory over the Athletics on Saturday night. Millwood had to leave the game in the first inning when he strained the muscle.
He will be reevaluated on Sunday and then the Rangers will decide if he has to go on the disabled list, if he'll miss just one start or if he can pitch on Friday against the Astros.
"The doctor will have to see how it is," Millwood said. "Hopefully it's not too bad, but I don't know right now."
The injury occurred while Millwood was pitching to just his third batter. He started the game by getting Kurt Suzuki and Daric Barton on fly balls, then came up hurting on his third pitch to Jack Cust.
"I felt it on the 1-0 pitch to Cust," Millwood said. "I tried to throw another pitch and I felt the same thing."
Manager Ron Washington and pitching coach Mark Connor went to the mound to check on Millwood, who tried to throw one warmup pitch, but couldn't continue. He was replaced by Josh Rupe.
Millwood's next day to pitch is Thursday, but the Rangers are off that day. He was supposed to pitch on Friday against the Astros, but the off-day gives the Rangers an option. They could just skip his turn and let everybody else stay on their regular rest. That would mean Millwood wouldn't have to pitch again until May 20 against the Twins.
But if he's going to be sidelined longer than just 10 days or they need an extra arm up here now, then they may put Millwood on the disabled list.
"We'll just have to talk about it and see," Washington said.
