Webb to get MRI on Tuesday

ARLINGTON -- Brandon Webb will undergo an MRI on his right shoulder on Tuesday. Webb, who has been on the disabled list since Spring Training, was scratched from a medical rehabilitation assignment on Friday when his shoulder tightened up.

"This is certainly a setback and an unfortunate one," Rangers assistant general manager Thad Levine said. "We'll know the extent of it on Tuesday."

Webb hasn't pitched in the Major Leagues since Opening Day of 2009 with the Arizona Diamondbacks. He was the 2006 National League Cy Young award winner and a 22-game winner in 2008 but has been sidelined for over two years with shoulder problems. He had surgery on Aug. 3, 2009.

Washington, Pettis ejected against Marlins

ARLINGTON -- Rangers first-base coach Gary Pettis and manager Ron Washington were ejected by first-base umpire Angel Hernandez in the seventh inning of Texas' 5-2 loss to the Florida Marlins on Sunday.

As soon as Marlins pitcher Michael Dunn threw to first in an attempt to pick off Nelson Cruz, Pettis could be seen pointing at Dunn, seeming to suggest that Dunn balked.

After a short rundown, Cruz was tagged out. Pettis was inquiring to Hernandez about a balk, and soon afterward, was ejected.

Washington felt Hernandez ejected Pettis without any sort of provocation.

"[Pettis] didn't [erupt]," Washington said. "Angel is just bad. That's all there is to it."

When Washington stepped in to clarify the situation, Washington got visibly angry. He got in Hernandez's face and kept shouting until he was tossed as well.

"I was out there to see what went on with Gary, and [Hernandez] said something to me, and I said something to him," Washington said. "Next thing I know, I'm gone, too."

The ejections mark the second of the season for both Pettis and Washington.

"I must have said something I shouldn't have, and I guess Gary did, too," Washington said.

Rangers keeping Ogando on schedule

ARLINGTON -- The Rangers are sticking with their current rotation, which means Alexi Ogando is still scheduled to pitch Wednesday against the Orioles and Derek Holland on Thursday against the Athletics.

A three-game losing streak had the Rangers considering the possibility of temporarily taking Ogando out of the rotation until after the All-Star break. But that idea appears to be scrubbed after Ogando allowed two runs over 6 2/3 innings in a 15-5 victory over the Marlins on Friday.

"Right now, he's pitching," manager Ron Washington said. "We haven't sat down and talked about it or made any decision. Our plan is to give him another start."

Holland was a candidate to come out of the rotation after allowing five runs in two-thirds of an inning on Saturday against the Marlins. But the Rangers are sending him back out there on Thursday.

"I don't see any reason why he shouldn't," Washington said.

The Rangers do have an option. They could recall Scott Feldman, who is 2-0 with a 3.23 ERA in six Minor League starts, off the disabled list. But right now the plan is for Feldman to make another rehab start for Triple-A Round Rock on Tuesday.

Tommy Hunter will remain in the bullpen, where he can be used in a variety of roles. He was used in long relief on Saturday night after Holland came out, allowing two runs in 4 2/3 innings.

"He can do whatever," Washington said. "We needed him last night."

Worth noting

• Rangers catcher Mike Napoli is expected to be activated off the disabled list on Monday after being sidelined with a strained oblique muscle in his left ribcage.

• Shortstop Elvis Andrus is now only the third player in Rangers history to have at least three straight 25-plus stolen base seasons.

• Triple-A Round Rock pitcher Mark Hamburger has not allowed a run over 11 1/3 innings in his last six outings.
