NEW YORK -- Rangers pitchers Scott Feldman and Eddie Guardado are both getting a couple of extra days off.

Guardado was unavailable to pitch on Tuesday night, one day after having to come out of Monday's game with inflammation in his left shoulder. Guardado came in and warmed up to pitch the eighth inning, but he had to come out when he felt the shoulder act up.

The Rangers are hoping he'll be ready Wednesday, but it's more likely that he won't pitch until Friday, when they open a three-game series with the Orioles in Baltimore. Guardado has been dealing with this all year and had to go on the disabled list in April. But he has been able to control it since then and has been one of the Rangers' most effective relievers.

"You get aches and pains here and there, but it's nothing I can't deal with," Guardado said. "When I got warmed up in the bullpen, it felt fine, but in my last four pitches warming up on the mound, I felt it pinch. I tried to throw through it, but it wasn't happening. The thing that makes you mad is you can't compete. That's why I was mad."

The Rangers, who play the Yankees again Wednesday and are off Thursday, have not discussed putting Guardado on the disabled list.

"The worst-case scenario is he'll be ready for Baltimore," manager Ron Washington said.

Feldman is fine physically but is starting to pile up innings in his first year as a starter. So the Rangers are going to use Thursday's day off to give him extra rest. Feldman's turn comes up on Sunday against the Orioles, but he's being pushed back to Tuesday against the Angels.

"We just want to give him a break," pitching coach Mark Connor said. "He's pitching more innings than he ever has in his career. We've talked about this off and on. He still gets two more starts before the All-Star break."

Feldman, who switched from the bullpen to the rotation at the end of Spring Training, has pitched 78 innings this season. He pitched 69 innings last year, 68 2/3 innings in 2006 and 79 1/3 innings in 2005 as a reliever in the Major and Minor Leagues.
