NEW YORK -- The Rangers are expecting catcher Jarrod Saltalamacchia to join Triple-A Oklahoma City on Sunday in preparation for a medical rehabilitation assignment sometime next week.

Saltalamacchia will likely just work out with the RedHawks for a couple of days before he actually starts playing in games on rehab assignment. That could be either Tuesday or Wednesday.

Saltalamacchia is sidelined with stiffness in his upper back and left shoulder and is eligible to come off the disabled list on Friday. But the Rangers want him to work up to nine innings and leave no doubt that he is healthy before they consider activating him. That could be a week or longer.

"We need to see that he's healthy," manager Ron Washington said. "We'll just wait and see how it goes. We'll be in touch with them every night and see how it goes."

Saltalamacchia had shoulder surgery last September and has had a number of physical setbacks since then. He had to leave winter ball after just two games in December, he was shut down twice in Spring Training because of back and shoulder problems and he went on the disabled list after just one game in the regular season.

With Matt Treanor on the big league roster and playing well as the backup catcher, the Rangers are in no rush to get Saltalamacchia back.

Conditions not cooperating for Kinsler

NEW YORK -- Cold and damp weather in New York is not helping second baseman Ian Kinsler, who is sidelined with a sprained right ankle. The Rangers aren't eager for him to test his ankle by running full speed in this weather.

Kinsler is taking batting practice, playing catch, fielding some ground balls and doing some agility drills. But he has not run the basepaths, done any stopping, starting or acceleration, and really hasn't tested the ankle with serious cutting in different directions.

"Hopefully the weather is good in Boston and we can get on the field and do some things," manager Ron Washington said.

Kinsler had a suggestion how to test the ankle in Boston.

"Boston Marathon," he said.

The Rangers fly to Boston Sunday night. The marathon is Monday. Kinsler won't run in it and he won't be playing in a game anytime soon. He has been sidelined since March 12 and the ankle is still not close to 100 percent.

"I'm waiting to get over the hump, but it's stuck right now," Kinsler said.

Feldman-Wilson swap may be imminent

NEW YORK -- The Rangers haven't made a final decision but they are leaning toward swapping Scott Feldman and C.J. Wilson in the rotation. Wilson is scheduled for Thursday in Boston and Feldman on Friday in Arlington against the Tigers.

But it may be that Feldman pitches against the Red Sox on Thursday and Wilson goes Friday against the Tigers. That would allow the Rangers to keep Matt Harrison and Wilson from pitching on back-to-back days.

"We don't want them back-to-back," manager Ron Washington said.

'Every day a new day' for struggling Teagarden

NEW YORK -- Taylor Teagarden, after striking out twice against CC Sabathia on Friday, is now 0-for-16 with a team-leading 11 strikeouts going into Saturday's game. That's the most at-bats for any Major League hitter without a base hit so far this season.

"It's not great," Teagarden said. "I'm struggling a little bit, but I'm working hard to get things turned around. You've got to have a short memory. Every day is a new day. You have to have confidence in what you're doing and play the game. If you let numbers clog your mind, you're not going to focus on the task at hand."

Teagarden thinks he's coming off his back leg too quickly and lunging at the ball. That's keeping him from having a good look at pitches and making his swing a little long.

"If I can clean that up, my swing will be a lot shorter," Teagarden said.

Teagarden started on Friday after missing two games because of a case of food poisoning. He admitted he wasn't 100 percent and that was a factor in the first-inning passed ball that allowed the Yankees to score their first run off pitcher C.J. Wilson.

"My glove felt heavy and I couldn't move around for three or four innings," Teagarden said. "C.J.'s ball was really moving around and I wasn't moving around. I could tell I wasn't 100 percent."

Worth noting ...

Manager Ron Washington said Matt Treanor will start at catcher on Sunday. ... Pitcher Tommy Hunter, on the disabled list with a strained oblique muscle in his left ribcage, threw 45 pitches in a bullpen on Saturday in Arizona without problem. His next step should be live batting practice on Sunday and he could start pitching in an extended Spring Training game later in the week. ... C.J. Wilson is the 14th pitcher in Rangers history to pitch a complete game in less than eight innings. He went six in Friday's rain-shortened game.
