Kinsler's stress fracture was revealed when he had an MRI on Monday in Dallas. He was hitting .241 with 14 home runs and 35 RBIs in 74 games.
The Rangers are now without three of their four starting infielders from Opening Day. Mark Teixeira is on the disabled list with a strained quadriceps muscle and Hank Blalock is still expected to be out for at least another 4-6 weeks while recovering from Thoracic Outlet Syndrome surgery.
"My take is somebody just has to step up," manager Ron Washington said. "It always hurts when you lose a regular guy, but it's not something we talk about. You've got to go with the guys you have."
Hairston hurt his knee in Saturday's game and was out for the second straight game. He was in the original lineup but was scratched after testing the knee in batting practice.
"It's better, but we don't want to rush it and have it linger for a week to 10 days," Hairston said.
No problems with Scioscia:
Angels manager Mike Scioscia wasn't too thrilled that shortstop Orlando Cabrera was left off the All-Star team because the Rangers needed a player and Michael Young was chosen by Tigers manager Jim Leyland.
"This isn't a knock on Michael Young -- he's an All-Star player, an unbelievable talent," Scioscia said. "But Orlando's having a better year, no question about it. [Carlos] Guillen's having a terrific season, too."
Young didn't have a problem with what Scioscia said.
"That's fine with me," Young said. "A manager should step up for his player, especially Cabrera. He's having a great year. It's nothing personal. He's pulling for his own guy.
"You look at the numbers and Orlando Cabrera is more deserving. This isn't a perfect process picking an All-Star team. I didn't make the rules. I've been chosen by [Leyland] to go out and represent this team and that's what I'm going to do."
Daniels continues to talk trades with other teams and closer Eric Gagne is among those coveted by teams. But Daniels may approach Gagne's agent, Scott Boras, to see if there's a way to keep him beyond this year and his current one-year contract.
"I wouldn't rule it out," Daniels said.
The big question is if the Rangers' hot streak will make them reluctant to trade off veterans and potential free agents before the July 31 trade deadline.
"Our stance if there's something we're comfortable that it will make us a better organization we'll do it," Daniels said. "But I'm not going to do something just for the sake of doing it. I'm very realistic where we're at. We've dug ourselves a big hole. But there's stuff to be gained the rest of the season by our young guys playing in a positive and winning atmosphere."
The Rangers aren't suggesting this is anything serious, but reliever Akinori Otsuka will be unavailable for at least a couple of days while dealing with stiffness in his elbow.
"It's a little sore," Otsuka said Monday before the Rangers' game with the Red Sox.
Washington said the Rangers won't use Otsuka at least on Monday and Tuesday, if not longer. But they still think he won't be available for an extended period of time. The Rangers also went into Monday's game hoping to stay away from using Gagne after he had pitched two straight games.
Arias has surgery:
Rangers Minor League shortstop Joaquin Arias played in just three games at Triple-A Oklahoma before being shut down and undergoing arthroscopic surgery on his right shoulder.
The Rangers are hoping that Arias will be able to resume playing before the end of the Minor League season. The problem has been bothering him since almost the beginning of Spring Training.
He said it:
"I don't make that decision. I'm just happy things are going well for me. I'm happy [Young] will be representing the whole organization. It's a decision that came from Jim Leyland and he thought he could do better with Mike."
-- Sammy Sosa, on not making the All-Star team
Sunday's Minor stars:
Gold: Eric Hurley was outstanding in a 3-2 victory over Omaha with six scoreless innings. He allowed three hits and one walk while striking out nine.
Silver: Jason Botts provided all of Oklahoma's runs against Omaha with two home runs and three RBIs. Botts is now hitting .317 with 10 home runs and 62 RBIs in 82 games.
Bronze: Double-A Frisco pitcher Luis Mendoza improved to 9-0 with a complete game against Springfield. He allowed two runs on six hits and four strikeouts without walking a batter.
Briefly: Washington said he thinks regular time off has helped Kenny Lofton, their 40-year-old center fielder who entered Monday's game hitting .306. But Washington said he's planning no more days off for Lofton between now and the All-Star break. ... Daniels on Hurley's performance: "It was a very encouraging outing. He threw strikes ... 70 percent strikes, and his breaking ball was good for him. The outing was encouraging."
Up next: The Rangers return to Rangers Ballpark in Arlington to open a three-game series against the Los Angeles Angels of Anaheim at 7:35 p.m. ET on Tuesday. Right-hander Kevin Millwood pitches against Ervin Santana. The Rangers have lost six of seven to the Angels this year.
