Kinsler put on disabled list

Infielder may miss rest of season; Arias called up

ARLINGTON -- Ian Kinsler is on his way to the disabled list and he may remain there for the rest of the season.

Kinsler underwent an MRI on Monday afternoon with team physician Dr. Keith Meister and the initial prognosis was that Kinsler has a sports hernia. Kinsler will seek a second opinion from a specialist that Meister recommended as soon as he can, but he had come to terms with the strong possibility that he's going to be out for a while.

Infielder Joaquin Arias was in the Rangers clubhouse before Monday's game and was called up from Triple-A Oklahoma to replace Kinsler.

"Pretty much, I'm on the DL," Kinsler said.

The only questions now are the severity of the injury, if it is in fact a sports hernia, and whether or not Kinsler will have to have surgery, which is the normal result of a sports hernia.

If Kinsler can simply rehab the injury, he could return this season. If he undergoes surgery, he will miss eight weeks, which would end his season.

"Hopefully, I don't have to get surgery, but I'll just go by what this doctor says," Kinsler said. "Hopefully, he says it's not as bad as we thought."

Kinsler suffered the injury on Sunday night against the Rays. He made a play on a ground ball to second base in the first inning and first experienced some discomfort in his left groin, but remained in the game.

Kinsler felt the same symptoms later in the game when he grounded out to third in the seventh inning and didn't come out for the eighth. However, Kinsler didn't think anything -- ranging from leaving the game earlier to altering his weight lifting regimen -- would have prevented the injury.

"There's a few instances that I think back to that maybe did it, but the first inning probably was what did it," Kinsler said.

This is the third year in a row that Kinsler has gone on the DL and the first time that he's suffered such an injury. Kinsler was on the DL from April 12 to May 25 in 2006 with a dislocated left thumb. Last season, he was on the disabled list from July 2-31 with a stress fracture in his right foot.

While Kinsler is out, manager Ron Washington will use a platoon of Arias and Ramon Vazquez at second base, depending on who is playing third base and what opposing pitcher the Rangers are facing. Brandon Boggs started in the leadoff spot in place of Kinsler on Monday.

Against left-handers, Arias would play second base and Travis Metcalf would start at third while Vazquez would likely play second base against right-handers. Then Chris Davis could play third base and Frank Catalanotto could play first base.

The situation may get simpler by the end of the week if Hank Blalock is able to play first base and Davis is able to play third base full-time. That remains to be seen.

"This obviously hurts," Michael Young said. "We can't replace [Kinsler]. We won't be able to duplicate what he does on the field every night. We'll just have to pick up the pieces and claw our way through this."
