Mitchell rehabbing; Peavy resting

BALTIMORE -- The White Sox provided a recovery update Sunday concerning Jared Mitchell, the team's top pick in the 2009 First-Year Player Draft, and ace hurler Jake Peavy.

Mitchell, the 21-year-old, five-tool prospect, tore a tendon on the inside of his left ankle while making a catch at Diablo Stadium in Tempe, Ariz., during Spring Training, sidelining him for the entirety of the 2010 season. Mitchell's on-field target remains fall instructional league, and is progressing "very well," according to White Sox athletic trainer Herm Schneider.

Mitchell continues to work on hitting, running, agility and taking fly balls at Class A Winston-Salem, within a controlled environment. Mitchell is also working on getting stronger as the ankle heals.

Peavy had surgery performed on July 14 to repair a detached latissimus dorsi muscle in his right posterior shoulder. He is resting until the six-week mark following surgery and will then be evaluated.

"Obviously, it was a major deal," said White Sox general manager Ken Williams. "But as far as the prognosis, I haven't been given any reason to think he won't be ready for Spring Training."

Beckham leaves game with groin injury

BALTIMORE -- Gordon Beckham left Sunday's 4-3 loss to the Orioles at Camden Yards in the fifth inning with a moderate right groin strain.

Beckham suffered the injury in the second, when he made a diving stop on Josh Bell's ground ball up the middle, and then got up to throw out Jake Fox at the plate. Brent Lillibridge pinch-hit for Beckham leading off the fifth and took over at second base.

White Sox manager Ozzie Guillen doesn't expect Beckham back for Monday night's series finale with the Orioles. Beckham wasn't sure about Tuesday's series opener at home against the Twins.

"I don't know. We'll try to do a few things tomorrow and see how it feels," said Beckham, following Sunday's setback.

After making the play, Beckham actually thought an equipment problem was causing pinching in the injured area. But it started getting tighter as he stayed out there.

"If I had hit a single and tried to stretch it into a double, there could be some trouble," Beckham said. "It would have been taking a big chance. I don't think it's a big deal right now."

Lillibridge will start in Beckham's place.

Teahen to continue rehab a while longer

BALTIMORE -- The .364 batting average produced by Mark Teahen during his current injury rehab assignment for Triple-A Charlotte seems to indicate the utility infielder is ready to return to the White Sox.

But look for Teahen to potentially stay the full 20 days allotted to work back into form after fracturing his right middle finger on May 30, especially with the return plan for Teahen not focusing solely on playing third base.

"I'm not going to say he's going to play third base," said White Sox manager Ozzie Guillen of Teahen, who began the season as the team's regular third baseman and started his rehab assignment on July 31, but wouldn't have to come back until Aug. 20. "He isn't going to play third base every day. He won't. Vizquel is playing very well."

"If he's playing one position, then it's probably less time because he's focused on one defensive position," said White Sox general manager Ken Williams of Teahen being targeted as a utility player. "And it's just not the work you're getting in at the position. It's balls hit in the game that you're getting. Those are balls you can't simulate in a ground ball session. You got to simulate those in the games."

Teahen has been used at third base, at designated hitter and in right field with Charlotte. He also will see time at first base, although Williams said Sunday that the White Sox don't envision Teahen playing at second or in left field.

In games started by Vizquel at third base in Teahen's absence, the White Sox have a 26-13 mark. They are 12-6 with Dayan Viciedo at third base.

There's no question Vizquel stands as the best defensive option of the three, but the 11-time Gold Glover at shortstop would win that battle against most Major League players. And Guillen certainly would never pin the team's turnaround to Teahen's absence.

"I can't say that. We take off because we pitch better. I can't point the finger at one kid," Guillen said. "When Teahen was here, our ERA was like 7.00 and our hitting was like .210. We played bad as a team everywhere. Maybe one guy was playing good, it was [Paul Konerko] and [Alex] Rios. Everyone else was very, very bad."

"We don't want to skip a beat whenever he comes back, whether it's offensively or defensively," Williams said. "And he was out quite a while. So it's not going to hurt him to have more time at the plate and at the various positions. There's no rush."

Pierzynski ready to go after injury

BALTIMORE -- A.J. Pierzynski's absence from Sunday afternoon's lineup vs. the O's simply was a scheduled day off, according to White Sox manager Ozzie Guillen. Pierzynski reported no residual pain or bad side effects from tweaking his left ankle in the seventh inning of Saturday's 4-2 victory, rolling his ankle on the base when he failed to slide upon taking third on his game-tying double to right.

"Hopefully he can play in an emergency," said Guillen of his starting catcher. "He told me he should be out there. He has some color out there [in the ankle], but he should be playing [Monday]."

Guillen was looking at the play at the plate on Alexei Ramirez when Pierzynski stumbled and then fell on his back side.

"It caught him by surprise when the catcher threw the ball to third base," Guillen said. "I think that's what happened."

Garcia part of Chicago's strong rotation

BALTIMORE -- When the White Sox first acquired Edwin Jackson, general manager Ken Williams discussed the great starting staff the team had assembled not only for 2010, but also for '11. Williams talked about John Danks, Gavin Floyd, Mark Buehrle, Jackson and even the injured Jake Peavy, but failed to mention Freddy Garcia.

Yes, the same Garcia who has been one of the team's most consistent pitchers during this entire campaign. That oversight could be tied to Garcia's impending free-agent status, but whatever the reason, Williams rectified that unintentional slip up before Sunday's contest with the Orioles.

"You certainly still have Freddy Garcia," Williams said. "Although Freddy Garcia will be a free agent, Freddy Garcia needs to be discussed in this conversation, so I look at it as going into the offseason with six starters -- assuming Freddy might want to be back.

"And if you got those six, you can play with it -- where you want to go. Do you want to use that starter -- one starter -- to go get something else?"

Garcia enters his next start against the Twins with a 10-4 record, although he has lost two potential second-half victories in Minnesota and Detroit. All Garcia worries about, though, is his next trip to the mound.

"I feel fine," Garcia said. "I just have to be ready every five days."

White Sox happy with what they have

BALTIMORE -- White Sox general manager Ken Williams is cognizant of his current squad's great makeup and the feeling in the clubhouse as to how this team as constructed is good enough to win. That feeling led Williams to look only for truly impact additions at the non-waiver Trade Deadline and beyond.

"I doubt very seriously if any one of them would have been complaining if that impact guy would have been walking through the clubhouse," Williams said. "They have to do what they have to do, and I have to do what I see as best as well. And sometimes they're in conflict with one another, and sometimes they're not.

"Generally, when I've had someone walk through that door that I know will be received well, it's been received well," Williams said.

Worth noting

White Sox broadcaster Steve Stone, who won the AL Cy Young with Baltimore in 1980, threw out the ceremonial first pitch on Sunday. ... Harold Baines, on hiatus from his first-base coaching duties after knee replacement surgery, was recognized by the Orioles' crowd following a video montage honoring him during the 4-3 loss on Sunday.
