CLEVELAND -- One swift post-appearance act could cost Tribe southpaw Nick Hagadone eight to 10 weeks.

Hagadone underwent surgery on Tuesday at the Cleveland Clinic after he suffered a self-inflicted injury to his left hand last Friday following a shaky outing. Dr. Thomas Graham inserted a screw and repaired Hagadone's fractured left radius, which is the forearm area above the wrist.

"I think he learned his lesson," Indians manager Manny Acta said Thursday. "A big part of this game is being able to control your emotions. He was frustrated and obviously ended up hurting himself."

Hagadone, 26, was optioned to Triple-A after his outing on Friday and Cleveland recalled lefty Scott Barnes to fill the open spot in the bullpen. Hagadone had posted a 16.43 ERA over his last 10 appearances for the Indians after compiling a 2.04 ERA in his first 17 outings of the season.

"The only thing it does is narrow our options," Acta said. "We have one less guy. We can go with Tony [Sipp] and [Scott] Barnes. And then where are we going to go from there? [Now] we won't have Nick go to Triple-A and have him work out his issues and then come back and take another shot. That's the issue with it is that our options are limited now."

On Sunday, the Tribe placed Hagadone on the disqualified list, making him ineligible for pay. Executive director of the Major League Baseball Players Association Michael Weiner told members of the Baseball Writers' Association of America that the MLBPA is considering filing a grievance over the Indians' handling of Hagadone's situation. Weiner said Hagadone's injury could be deemed "work-related."

"Clubs want players to compete, to compete very hard, and sometimes those emotions come out," Weiner said Tuesday in Kansas City. "No player is proud of the fact that he injured himself in that kind of situation. But Nick is not the first player this year, and certainly not the first player in baseball history, who unfortunately suffered that kind of injury."

Ubaldo points to mechanics for recent success

CLEVELAND -- What a difference a year makes for Ubaldo Jimenez.

After the All-Star break last July, he rejoined the Rockies -- the only team he had been with during his 10-year professional career -- only to be traded a couple of weeks later.

"Last year, it was hard for me," Jimenez said. "After I came from the four-day break, the first thing I heard was, 'You're going to get traded.' So that was really hard."

Jimenez never found his groove in 2011 after Cleveland acquired the right-hander for its top two pitching prospects -- Drew Pomeranz and Alex White -- in addition to two other Minor Leaguers. Jimenez went 4-4 with a 5.10 ERA in 11 starts with the Tribe in the second half of the 2011 campaign as the Tribe faded from contention in the American League Central.

After a sluggish start to the 2012 season, Jimenez has flashed signs that he has turned a corner.

"This year," Jimenez said, "I'm only thinking about what I'm going to do in my next start and how I can help the team."

He's certainly given his club a lift of late, and he credited his recent success to rectifying a mechanical flaw in his delivery. In his last seven outings, Jimenez is 3-3 with a 2.93 ERA. He has limited opponents to a .226 batting average during that span.

"It was all about the mechanics," Jimenez said. "I've been able to go out there just thinking about getting everybody out, instead of thinking, 'I have to do this or that to get better.'"

For Indians, season hinges on hitting stride

CLEVELAND -- The Indians are holding out hope that they can eventually fire on all cylinders during the second half of the season.

After all, despite their 44-41 record, which positions them three games out of the American League Central lead, they have yet to hit their stride in any facet of the game.

"We haven't put together our defense, pitching and hitting at the same time," said right-hander Ubaldo Jimenez. "That's probably something we have to work on in the second half."

Of the four pitchers who have made at least 10 starts for Cleveland, Justin Masterson possesses the lowest ERA, at 4.40. In the bullpen, only Joe Smith, Vinnie Pestano and Chris Perez have kept manager Manny Acta's heart rate at a healthy level.

Offensively, no Indians player is batting .300, and catcher Carlos Santana totes just a .221 average with five homers. Designated hitter Travis Hafner, who recently returned from knee surgery is hitting .231.

"We need Carlos and we need Hafner to have our offense competing at the level we believe it can," Acta said.

Worth noting

• The Indians have signed 23 of their 40 picks from June's Draft. On Thursday, they locked up 39th-round selection D.J. Brown, a 21-year-old right-hander from James Madison University. On Tuesday, they agreed to terms with a pair of 20-year-old right-handers: 24th-round choice Thomas White, from South Georgia College, and 36th-round pick Benny Suarez, from Hill Junior College (Texas).

• The Indians named Class A Mahoning Valley infielder Joey Wendle the Minor League Player of the Week for July 1-8. The 22-year-old batted .400 (12-for-30) with four doubles and eight RBIs, including a 3-for-6 effort with four RBIs on July 1. During the stretch, he raised his batting average to .356 from .320. Wendle was the Tribe's sixth-round selection in the 2012 First-Year Player Draft out of West Chester University (Pa.).

• The Tribe partnered with Ace Program, Inc. to launch the Indians Youth Baseball Program, which offers kids the chance to learn baseball, hone their abilities and continue their development on the field in summer camps, fall leagues and Baseball Buddies programs.
