Buzz: Cruz headed to the Dominican to train

ARLINGTON, Texas -- Texas Rangers outfielder Nelson Cruz will spend the next 12 days in the Dominican Republic training at his home gym, the first step to possibly returning to the team when his 50-game Biogenesis suspension is completed.

That would coincide with the Rangers making the postseason. And as far as that goes, the Rangers haven't made a decision yet about whether he'd play. They have to get there first.

"Our goal right now, as it always is, is to keep our options open," Rangers general manager Jon Daniels said. "We want to do what we can to keep him [in] as good as shape as possible, as good as baseball shape as possible.

"First of all, we have to get there. We’re not going to get ahead of ourselves. We’ve got to get there first to have the conversation."

Daniels repeated what he said last week when Cruz was suspended for the rest of the regular season. The All-Star outfielder's conditioning, how the team is playing, how the club is jelling, all of that will factor into the Rangers' decision.

At that point, the Rangers would probably let Cruz play in games in the fall instruction league.

Daniels said Cruz will also work out a few times at the Rangers' complex in Boca Chica while he is home.

"He’s been in touch with our conditioning staff and has his program," Daniels said. "Once he gets back, we’ll have a next step at that point."

Washington on Harrison: The Rangers announced Tuesday that left-handed starter Matt Harrison will not pitch again this season because of issues with his surgically repaired back.

Harrison will rest and get ready for the offseason and spring training. There is no structural damage to his back, so Harrison should return ready to go in 2014.

"It's disappointing for Harrison's sake," Rangers manager Ron Washington said. "He worked so hard to get back. It just didn't work out. It's just another adverse happening in our 2013 year as the Texas Rangers. We'll figure out a way to move forward and wish Harrison good health."

Rosales hopes to settle in: Utility man Adam Rosales started his second stint with the Rangers on Tuesday after being reclaimed by Texas on Monday.

Since Aug. 2, he has been on the Oakland A's roster twice and now the Rangers twice as the teams have swapped claiming him off waivers. He made a smart move by leaving his car in Dallas. Rosales realizes that until Sept. 1, when rosters expand, he's on standby.

"I didn't have any options yet so teams have to designate me," Rosales said. "That's why we're playing pingpong."

The Rangers have a bigger need for Rosales this time around after Triple-A Round Rock infielder Leury Garcia went to the Chicago White Sox on Sunday to complete the Alex Rios trade.

"With us giving up Leury, we certainly didn't have anything to back up our infield," Washington said. "We wanted him when we claimed him the first time. We were just hoping no one would claim him when we put him back out there."

Berkman's running still issue: Designated hitter Lance Berkman was set to play Tuesday and Wednesday for Double-A Frisco, provided the weather cooperated.

He was 3-for-7 with a home run in two games with Triple-A Round Rock. But running on his ailing left hip and right knee has still been difficult.

"He swung the bat well," Washington said. "He's still having issues with the running. We'll see if it's getting better with two games in Frisco."

Short hops: Right-hander Neftali Feliz is still day-to-day with Triple-A Round Rock due to triceps tendinitis. He's scheduled to throw a bullpen session Wednesday. ... Round Rock catcher Eli Whiteside, a possible call-up when rosters expand in September, was 3-for-4 with his fifth home run Monday. ... Joe Nathan earned his 35th save in Houston on Monday, giving him eight seasons with 35-plus saves. The only other two closers to do that in major league history are Mariano Rivera and Trevor Hoffman, who have each done it 12 times.
