ARLINGTON -- Rangers pitcher Alexi Ogando had an MRI on his strained right groin Monday, but a decision on whether or not to place him on the disabled list will not be made until as early as Tuesday.

Ogando sustained the injury while beating out a bunt single in the fourth inning of the Rangers' 5-0 win over the Giants on Sunday. The right-hander, making his first start of the season, had thrown three scoreless innings until that point, retiring all nine batters he faced. Ogando, a 13-game winner and All-Star starter last season, was replacing Derek Holland in the rotation after Holland was placed on the 15-day DL with left shoulder fatigue.

Team physician Dr. Keith Meister was out of town while Ogando had the MRI and will not be able to evaluate it in time for the Rangers to make a decision on Monday.

If Ogando does land on the DL, he will become the third Rangers pitcher to do so in the last four weeks. Before Neftali Feliz went on the 15-day disabled list with right elbow inflammation May 21, the Rangers had not made a roster move. Holland, who was also suffering from a stomach illness, joined Feliz on the DL last Thursday.

Nelson Cruz also missed Sunday's game after hurting his right Achilles tendon Saturday.

Mavs' Nowitzki to play in Frisco celebrity game

ARLINGTON -- Dirk Nowitzki and several of his Dallas Mavericks teammates, along with his head coach Rick Carlisle and owner Mark Cuban, will be a part of a celebrity baseball game that will take place at Frisco's Dr. Pepper Ballpark June 30.

"Dirk Nowitzki's 2012 Heroes Celebrity Baseball Game" will be played later this month where the Double-A RoughRiders play their home games. Mavericks players Jason Terry, Delonte West and Brian Cardinal, along with team president Donnie Nelson, will participate in the game. Proceeds from the event will benefit the Dirk Nowitzki Foundation and the Heroes Foundation.

Joining the Mavericks will be Daryl "Moose" Johnston, who helped the Dallas Cowboys win three Super Bowls, former Cowboys safety Roy Williams, former Texas Ranger Kevin Mench, and Arlington native Ben Grieve, a former Major League outfielder. FC Dallas players Ugo Ihemelu and Brek Shea are also set to play in the celebrity game.

Among the scheduled festivities include a Whataburger Heroes Special Olympics All-Star Softball Game and, for the first time, a Celebrity Home Run Derby. Fans interested in participating in the Home Run Derby will have the opportunity to try out June 22 at Hits400, a Plano batting cage. Following the celebrity baseball game, fireworks sponsored by Baylor Medical Center at Frisco will cap off the event.

Worth noting

• Triple-A Round Rock outfielder Julio Borbon went 3-for-5 with a double and two RBIs on Sunday to extend his hitting streak to 19 games.

• Double-A Frisco pitcher Justin Grimm had his scoreless innings streak snapped at 25 on Sunday, allowing three runs over seven innings in a 5-4 loss to Midland. Grimm got a no-decision and is 8-3 with a 1.87 ERA.

• Game times for three Rangers games have been moved, beginning with the July 22 contest against the Angels, which have been moved from 2:35 p.m. to 7:05 p.m. CT to accommodate an ESPN national telecast.

The Rangers' game against the Rays on Aug. 29 has been moved back from 7:05 p.m. to 6:05 p.m. because of the Dallas Cowboys' preseason game against the Miami Dolphins that night at 7:30 p.m.

Also, the team's game against the Royals on Sept. 4 will start at 5:10 p.m., instead of the originally scheduled 6:10 p.m.
