Odor, Sardinas to share second base

DETROIT -- The Rangers were hoping second baseman Jurickson Profar would be ready by early June. Instead he is likely to miss most -- if not all -- of the rest of the season after re-injuring the muscle in his right shoulder.

That means rookie infielders Rougned Odor and Luis Sardinas aren't going anywhere. Manager Ron Washington said they will continue to share second base. Odor will likely play more because he is a left-handed hitter but Washington said Sardinas, a switch-hitter, will play there as well.

"Those kids are not afraid to play," Washington said. "They are going to have some growing pains, but we're going to make them better."

Odor started on Friday night and went into the game with five hits in 28 at-bats (.179) since being called up from Double-A Frisco. Sardinas was 6-for-21 (.286).

"I don't think they look overmatched," Washington said. "There are some adjustments they are going to have to make. Every pitcher they face is new. All they know is what they have been told, seen or read. They have to make adjustments based on how they pitch. They have to go out and believe in themselves because we believe in them. That's why we're putting them out there."

Moreland gets job back at first base

DETROIT -- Mitch Moreland has his old job back. With Prince Fielder on the disabled list and preparing for season-ending surgery, Moreland is back to being the Rangers' everyday first baseman.

Moreland, who has made 20 of his first 30 starts at designated hitter, will play there against both right-handers and left-handers.

"I'm not going to prepare any different than the way I have all season," Moreland said. "It's not something new. It is what I've done for the most part since I've been here."

Moreland went into Friday's game hitting .275 with two home runs, 15 RBIs and a .413 slugging percentage. He has played sparingly against left-handers and is 2-for-15 off them. But the Rangers began a stretch on Friday where they could potentially face at least 10 consecutive right-handed starting pitchers.

"I'm going to put Mitch's name in the lineup and let him relax," manager Ron Washington said. "I'm not putting any pressure on Mitch Moreland. He's my first baseman, just go out and play. We can't replace Prince Fielder's production. We don't have that guy. Prince is on the disabled list. Nobody can replace him. Let Mitch be Mitch."

The Rangers don't have an experienced backup first baseman. The only two others who have played there in the Major Leagues are their two catchers. Chris Gimenez has played 22 games at first and Robinson Chirinos has played five. Brett Nicholas and Adam Rosales are currently playing first base for Triple-A Round Rock. The Rangers may use Donnie Murphy even though he has never played there.

"If they say something to me, I'd be up for it," Murphy said. "I've never played there but I would be up for it."

Asked who his backup first baseman was, Washington said, "Right now it's [bench coach] Tim Bogar."

Murphy gets the call to replace Fielder

DETROIT -- The Rangers activated utility infielder Donnie Murphy off the disabled list on Friday to take Prince Fielder's spot on the active roster. Murphy has been sidelined since May 8 with stiffness in his neck and was 1-for-19 in six games on medical rehabilitation assignment.

The Rangers selected Murphy over Brad Snyder, a left-handed-hitting outfielder who is hitting .264 with 13 home runs, 35 RBIs, and a .546 slugging percentage at Triple-A Round Rock. The Rangers already have five outfielders on the active roster in Shin-Soo Choo, Leonys Martin, Alex Rios, Michael Choice and Daniel Robertson. Murphy gives the Rangers a right-handed bat with some versatility.

The Rangers are looking outside the organization but are unlikely to pursue free agent Kendrys Morales. They have scouted his workouts in Miami, but do not want to give up their first-round Draft pick by signing him before next month's First-Year Player Draft.

Despite Fielder being the latest of many injuries, manager Ron Washington said he still expects to go out there and win every night.

"It's no secret what we're going through," Washington said. "I'm not Houdini, I don't have a crystal ball. I'm just putting the best lineup out there and believing we can win. We know it's a challenge, but there's not anything we can do but just show up and play. Anything beyond that is an excuse and we don't make excuses."

Robertson beat up but still active

DETROIT -- Outfielder Daniel Robertson had a black left eye and three small fractures in his left orbital bone after his face collided with Alex Rios' knee on Thursday afternoon. Robertson will have to wear a special face shield and batting helmet when he plays. But he said he only expects to be sidelined for a couple of days and does not need to go on the disabled list.

"We'll analyze it day by day but I should be ready to go in a few days," Robertson said.

The fractures will likely take four to six weeks to heal but doctors have told Robertson he can play with it while wearing the proper protective gear.

"They're not big at all," Robertson said. "My cheek is very similar to the other cheek. I could play today, but the discomfort and swelling would make it tough."

Worth noting

• The Rangers have not made any decision on when they will bring left-hander Joe Saunders off the disabled list and what his role will be. The Rangers will likely watch Scott Baker on Friday night and Nick Martinez on Saturday before making a decision.

• Pitcher Tanner Scheppers, who is on the disabled list with inflammation in his right elbow, will begin a medical rehabilitation assignment on Saturday. He is scheduled to pitch one inning for Double-A Frisco. He will likely be transferred to Triple-A Round Rock after that.

• Baker is the 10th starting pitcher used by the Rangers this season. It's the first time in club history they've used 10 different starters in the first 48 games.
