Greenberg heads purchase of Double-A team

OAKLAND -- Chuck Greenberg is once again doing business with the Rangers.

Greenberg, who was the driving force in the sale of the Rangers from Tom Hicks to the current partnership, has joined with Scott Sonju to purchase the Double-A Frisco RoughRiders from Mandalay Baseball. The agreement is subject to approval by the Texas League and Minor League Baseball.

The RoughRiders have been the Rangers' Double-A affiliate since 2003. Greenberg, who owns two other Minor League teams, including the Class A Myrtle Beach Pelicans, was the Rangers' CEO from 2010-11 before stepping down.

"This is an exciting time for us and RoughRiders fans across the Metroplex," Greenberg said. "The RoughRiders already have an outstanding operation and reputation and we are looking forward to further enhancing the fan experience at Dr Pepper Ballpark and throughout the community."

The Rangers' working agreement with the RoughRiders currently runs through 2018.

Daniels in no rush to make decisions about trades

OAKLAND -- With the July 31 non-waiver Trade Deadline still six weeks away, general manager Jon Daniels is in no rush to come to any conclusions about what the Rangers should do before then.

However, he made it clear the Rangers aren't particularly interested in being "sellers" anytime soon, if at all.

"Right now, we're taking the approach of letting the team play before making any decisions on what we're doing," Daniels said. "With the injuries and other things, we could use help, but at the same time, the team is starting to come together so we're going to use this time to observe and evaluate."

Injuries have had a significant impact on the Rangers' season, but teams that do sell at the Trade Deadline are often looking at major rebuilding programs. Even if the Rangers aren't able to stay in the race this season, they still expect to be contenders next season once guys like Prince Fielder and some others are healthy again.

"If we felt we couldn't be good next year, we'd look at it differently," Daniels said, "but the first thing is, we're not giving up on this season. We're challenged by the injuries, but we're still sitting at .500. Some clubs have separated themselves in both leagues, but beyond that, it's wide open."

That doesn't mean though that the Rangers will be buyers either, not after having given up so much Minor League talent over the past four years while adding players at the Trade Deadline and beyond.

"I'd like to have us settle in and play together a little bit," Daniels said. "It's not our style to give up on a season. We like to go for it when it's there, but you have to realistic."

Moreland to seek another opinion on left ankle

OAKLAND -- Rangers first baseman Mitch Moreland, on the disabled list with an injured left ankle, is going to Iowa to be examined by Dr. Ned Amendola, an orthopedic specialist. It will be the third specialist Moreland has seen as he tries to decide how to deal with the pain in his ankle.

Moreland is dealing with Os Trigonum Syndrome, which means there is a bone in the ankle that is causing pain. Moreland could have a simple operation to have the bone removed, which would mean missing about a month.

But there is a suspicion that a simple operation may not address everything wrong in the ankle. Moreland could end up having reconstructive ankle surgery, which would sideline him for the rest of the season.

"It's a pretty big decision and he wants to get it right," general manager Jon Daniels said. "The way Mitch is looking at it, when he comes back, he wants to be 100 percent. We all agree on that."

Rangers coaches have fond memories of Gwynn

OAKLAND -- Rangers hitting coach Dave Magadan spent the final three seasons of his 16-year Major League career with the Padres from 1999-2001. Those three years gave him a chance to learn much about hitting from Hall of Famer Tony Gwynn.

It was also toward the end of Gwynn's career when injuries started cutting into his playing time. So he and Magadan had plenty of time to sit on the bench and talk about the art of hitting.

"A lot of the routines I do with our guys in the [batting] cages are related to the discussions I had with him," Magadan said. "Like he was a big proponent of hitting off a tee ... a lot of that stuff I still teach today. He was very in-tune to himself as a hitter. He knew himself and could make adjustments pitch to pitch rather than at-bat to at-bat or game to game. He was one of the first to use video. He gave our video guy a lot of work, but he put it to good use. He was all business and all about doing what he could to help the team out."

Magadan is one of three Rangers coaches who played with Gwynn, who passed away on Monday at the age of 54. Bullpen coach Andy Hawkins was Gwynn's roommate as a rookie in 1982 with the Padres.

"He had great work ethic, always taking extra hitting," Hawkins said. "He was the reason we got a batting cage in San Diego, because he was always taking more batting practice than anybody else. He loved the game. Every time I saw him on the field he had a smile on his face. He was an easy-going guy to be around and a great competitor. Just a Hall of Fame player and a Hall of Fame person."

"He was one of the best teammates I've ever had," pitching coach Mike Maddux said. "I learned a lot about pitching from him. If I got stuck on a hitter, he would break down the guy's swing and tell you how to pitch to him. He was one of the best sources of baseball information I ever played with, a true baseball rat."

Worth noting

• The Rangers have promoted left-handed pitcher Will Lamb from Class A Myrtle Beach to Double-A Frisco. Lamb was taken in the second round of the 2011 First-Year Player Draft and had a 2.41 ERA in 14 relief appearances at Myrtle Beach.

• Former All-Star closer Neftali Feliz has a 4.35 ERA in 17 games at Triple-A Round Rock and the Rangers still aren't viewing him as an option at the Major League level. Said general manager Jon Daniels, "He has been OK, but from a consistency standpoint, it's not where we want it."

• The Rangers also aren't seeing what they hoped for from former Red Sox reliever Daniel Bard, who is trying to come back from offseason shoulder surgery. He has pitched in four games at Class A Hickory and allowed 13 runs on nine walks and seven hit batters. He has retired just two hitters. Said Daniels, "He has worked his tail off, it just isn't happening."

• The Rangers signed three amateur free-agent college players: right-handed pitcher Andrew Barrett from Gardner-Webb University, left-handed pitcher Shane McCain from Troy University and first baseman Zach Stephens from Tennessee Tech.
