ARLINGTON -- The Rangers' young players continue to take their lumps in the waning days of the season.

Rangers starter Kolby Allard allowed five runs over three innings in a 10-3 loss to the Red Sox on Wednesday night at Globe Life Park. The loss was the Rangers' ninth in the last 10 games.

"We just have to stay strong and give it everything we've got for the next four days," shortstop Elvis Andrus said.

Willie Calhoun, who started the game at designated hitter, left after getting hit on the left forearm by a pitch from Red Sox starter Rick Porcello in the first inning.

Calhoun suffered a left forearm bone contusion, and X-rays were negative. But he was in considerable pain after the game.

"It's just stiff and really sore," Calhoun said. "It got the muscle before it hit the bone. It really hurt bad at first. I couldn't feel my hand. I thought it was broken."

Calhoun joins a list of Rangers players who are doubtful for the final weekend, including Nomar Mazara (left oblique), Jeff Mathis (lower back) and Logan Forsythe (left intercostal). That does not even account for Joey Gallo and Hunter Pence, who have already been shut down. The Rangers are still hoping Calhoun will get back in their depleted lineup.

"We'll see how he feels," manager Chris Woodward said. "He doesn't feel real good right now, but we'll see how he wakes up. I would say he's doubtful for [Thursday] but after that he'll want to be in there. I think he will be fine ... it's just a matter of comfort for him at this point."

For Allard, this was the shortest of what has been a relatively effective nine-start stretch since being acquired from the Braves. He allowed five runs on six hits and a walk while striking out one. He ended up 4-2 with a 4.96 ERA for the Rangers.

"Kolby has done a good job," Woodward said. "Yesterday he didn't feel real well, he was kind of under the weather, so I felt that was kind of a carryover. He has been impressive. I know it has been a short amount of time, but his competitiveness, pitch selection he has, his stuff, it plays. His confidence on the mound and the way he attacks hitters plays. There are some things he needs to add and trust ... but I like him though, the kid has a really good makeup."

Wednesday was another September special for the Rangers' pitching staff. They used six pitchers, five rookies. The only seasoned veteran was right-hander Luke Farrell, who pitched two scoreless innings in his 39th Major League game.

The Rangers will take one more look at rookie left-hander Joe Palumbo, who is scheduled to start on Friday against the Yankees. But they are pulling the plug on Brock Burke. He was supposed to start on Saturday, before the Rangers decided against it after he allowed 19 runs over 8 2/3 innings in his last three games.

"Brock, the shoulder hasn't really felt good," Woodward said. "I believe he is going to get an injection, so we're just going to shut him down. I don't believe it makes any sense to push that."
