ARLINGTON -- The Rangers were the bearers of some good and bad news Monday on the pitching rehab front.

The positive: right-hander Brandon Webb threw a bullpen session in Surprise, Ariz., and reports back were good. Webb will pitch in an extended spring training game on Thursday.

The negative: Tommy Hunter's day did not go as well. Hunter, who has been out since Spring Training, pitched into the seventh inning for Triple-A Round Rock. On his 79th pitch, he tweaked the right groin strain he's been rehabbing. Dr. Keith Meister localized soreness in Hunter's groin, and he will undergo an MRI on Tuesday.

Scott Feldman worked 4 1/3 innings Monday without issue, allowing five runs on seven hits in extended spring training in Surprise, Ariz. Feldman will throw a bullpen session in Arlington in a few days and then likely go out on a rehab assignment, team officials said.

Beltre unwillingly gets first day off this season

ARLINGTON -- Third baseman Adrian Beltre has played every inning of every game for the Rangers, so manager Ron Washington decided Monday's series opener against the A's was a good day to give him a break.

Beltre started the first 35 games of the season. Only Michael Young, who has started 24 games as the designated hitter and 11 in the field, has started every game. Washington said he'll get Young a day off at some point.

Beltre asked to be in the lineup, but he lost the debate.

"I don't want it," Beltre said.

"This has nothing to do with where he is or what he's doing," Washington said. "I just think at some point I needed to get him a day, and after yesterday, and it was sunny and all of that, I just decided today was a good day to give him off."

Beltre has four hits in his past 30 at-bats. He was 1-for-4 with an RBI in Sunday's 12-5 loss to the Yankees, but he hasn't hit a home run in 14 games after hitting seven in the Rangers' first 21 contests.

"I didn't see anything," Washington said. "I see the same things you see. I just got a feeling that he needed a day. Maybe this mental day will be what he needs."

Hamilton to start batting practice on Friday

ARLINGTON -- Josh Hamilton will begin taking batting practice on Friday as long as he continues to progress.

Hamilton, out since April 13 with a non-displaced fracture of his right humerus bone, has been swinging off of a tee since last Thursday.

Hamilton said last Friday that he expected to need two to three more weeks before he could return from the injury. He has been feeling no pain in the area where he was injured, but team doctor Keith Meister has him taking rehab slowly.

Washington, Borbon talk about 'poor judgment'

ARLINGTON -- Center fielder Julio Borbon's attempted steal of third base with two outs in the sixth inning in Sunday's 12-5 loss to the Yankees was "poor judgment," according to Rangers manager Ron Washington.

Washington said he talked to Borbon about the attempted swipe. The Rangers were tied at 4 when Borbon was gunned down for the final out of the sixth. The Yankees hit back-to-back home runs in the top of the seventh to take a 6-4 lead that they never relinquished.

Texas' skipper made sure Borbon knows he can score on any kind of hit from second base, one of the few Rangers players with that capability.

"He's learning," Washington said. "Also, I feel like I've got to start stepping into those situations, because I would have never thought that would have happened. But it did. I'll take the blame for not stepping in and making sure he wasn't going anywhere."

Washington said he will have to keep Borbon from stealing in some instances, instead of giving him the automatic green light. The Rangers went through the same growing pains with shortstop Elvis Andrus last season.

"We knew it was going to be a development thing with him all season," Washington said. "But the last thing I want to do is take his aggressiveness away from him, because now we've got him playing the kind of baseball we know he can play. Now, we just have to get him thinking a little bit with that."

Washington did commend his young outfielder for tagging up and going from first to second base in that same inning on a fly ball to left field. Borbon enters Monday's action with an eight-game hitting streak and a .385 batting average.
