Millwood likely headed to DL

Rangers right-hander remains bothered by groin injury

OAKLAND -- Rangers pitcher Kevin Millwood is likely headed to the disabled list for the second time this season with a strained groin muscle.

The Rangers haven't made a final decision, but it's possible that Millwood will go on the disabled list on Sunday when Eric Hurley is activated. Millwood tried to throw on the side at McAfee Coliseum on Friday and it didn't go well.

Scott Feldman will start on Monday against the Mariners in Millwood's spot.

"I want to get it right," Millwood said. "I don't want to go out there and have it happen again. You can't say it will never happen again, but we want to make sure we do everything we can to get it right."

Millwood had to leave his last start on Wednesday in the second inning when the groin injury flared up again. Millwood was on the disabled list May 11-29 because of the injury and it continues to be a problem for him.

"The groin is an issue," Rangers pitching coach Mark Connor said. "The guy wants to pitch and he's trying to pitch but it's not helping him and it's not helping us."

The other option would be for Millwood to miss just one start and try to pitch next weekend in Arlington. That would keep him off the disabled list, but that option doesn't seem likely.

"I don't think that's going to be the case, not if we want to get him fully healthy," Rangers manager Ron Washington said. "It's a huge blow. He's the guy we depend on to set the stage for every other pitcher that goes out there."

Hurley's return from the disabled list was delayed by a sore right shoulder, but he threw 40 pitches in the bullpen on Friday and everything went well.

Feldman was supposed to spend the second half in the bullpen to keep his innings total down, but the Rangers haven't been able to do that because of all their injuries. He'll likely be in the rotation the rest of the year, but Connor said the Rangers will use off-days in the schedule to push him back when they can. That way, they can keep him under 150 innings for the season. He has already thrown a career-high 93 2/3 innings this season in his first year as a starting pitcher.
