Maintaining approach key to Dunn's revival

CHICAGO -- Adam Dunn has become a first-person authority on the sub-.200 batting average, and of course not by his own volition.

Dunn hit .148 in April and .165 in May this season, yet from the start of Spring Training, he spoke of how good he felt at the plate. The challenge for Dunn was not to start drastically changing his approach or make changes just to make changes, and holding steady has paid dividends.

Over his last 49 games entering Tuesday night, Dunn was hitting .306 with 13 homers and 36 RBIs. He had a .415 on-base percentage and a .571 slugging percentage since June 8 and had reached base safely seven times in his last two games.

"People always say, 'This game, it's 90 percent mental,'" Dunn said. "It's probably not that much, but it's a lot. That's the part of it. You struggle for so long, and the next thing you know, something has to be wrong.

"Well, not really. Mechanically, things don't have to be wrong. I can probably speak about that better than a lot of people because I've struggled for months at a time and felt good. So try to stay with it. It's just tough. It's a tough situation."

This resurgence has caused media speculation that Dunn -- who is owed $15 million in 2014, the final year of his four-year deal -- could be moved to a contender in August, during the waiver trade period. Dunn told MLB.com a few weeks ago that he wants to win in Chicago, but doesn't worry about things he can't control.

Viciedo grateful thumb injury merely a jam

CHICAGO -- When Dayan Viciedo made a diving attempt at Robinson Cano's first-inning single on Monday, he knew immediately something was wrong with his left thumb.

"It was right at that moment," Viciedo said through a translator, White Sox director of public relations Lou Hernandez. "I just landed on it and I had some really bad thoughts going through my head, if you know what I mean. Luckily, nothing's broken. When I got back to the dugout, I couldn't close my glove, and that's when I realized there's something wrong here."

X-rays taken on Viciedo's jammed thumb on Monday were negative. He didn't start Tuesday's contest against the Yankees but thought a return for Wednesday night's series finale was possible.

"Yeah, absolutely," Viciedo said. "It improved a lot from last night to now. Little by little, it's getting better.

"There's a little bit of swelling. Thank God there was no fracture. It was just a freak jamming, so the inflammation is there. They're doing some treatment on it to reduce the swelling and hopefully get me out there on the field as soon as possible."

Quintana reflects on lessons from suspension

CHICAGO -- The topic of Jose Quintana's 2007 suspension is brought up to the affable 23-year-old, and the left-handed hurler attacks the subject much like he did the Yankees during Monday night's 8-1 White Sox victory at U.S. Cellular Field.

Quintana was not even 17 and pitching in the Mets system when he was suspended for violating the terms of Minor League Baseball's drug policy. He sat out from May 15 to July 16 and was eventually released by the Mets, causing him to think that his professional career was over before it could begin.

"Absolutely, that passed through my mind," Quintana said through a translator, White Sox coach Lino Diaz. "I had four months where I was out of baseball, and I totally thought I was done. But I had really good people around me, especially my family, who supported me throughout all this."

After joining the Mets as a free agent on April 26, 2006, the native of Colombia tested positive in October of that year. Quintana admits now that his first reaction was to think the positive test was some sort of bad joke because he wasn't taking anything.

It was medicine that Quintana had been given for a back issue that caused the positive, according to the pitcher.

"I feel like it was lack of orientation more than anything," Quintana said "I was just taking medicine. I wasn't trying to get anything else. I was going to a gym where they had a sports medicine guy.

"So back then, I asked, 'Hey, I need something for my back -- but just something that is not going to be against what I'm doing.' And unfortunately, that came out."

One mistake did not erase Quintana's big league chances, as the Yankees signed him as a free agent on March 10, 2008. The White Sox picked up the lefty after he departed the Yankees in 2011, and he has since become a rotation mainstay.

That long chain of events culminated with Quintana facing the Yankees in Alex Rodriguez's return to action on Monday night. Quintana earned the victory, improving to 6-3 with a 3.51 ERA and 110 strikeouts over 138 1/3 innings. He's also 2-0 in his career against the team that kept his dream alive.

"I'll always be thankful to the Yankees for giving me that opportunity," Quintana said. "I learned a lot from that experience, and that's what's important to me now.

"I'm sure they don't really want to cause any harm or anything like that," added Quintana of those players who test positive. "You just have to be careful."

Ventura on Sox: 'We're all in it together'

CHICAGO -- White Sox manager Robin Ventura was informed prior to Tuesday's game against the Yankees that his charges don't necessarily agree with him and general manager Rick Hahn shouldering responsibility for this disappointing season, as both men did on Monday.

Ventura seemed to have had enough of this particular topic.

"I'm tired of talking about it," Ventura said. "As players, they have opinions, too. I have to take responsibility. We're all in it together. It's not them alone. That's about it.

"It's not going to change anything. We're trying to make do and play better. That's it."

Third to first

• The White Sox remain undecided as to their starter for the afternoon portion of Friday's day-night doubleheader with the Twins. John Danks will start the nightcap.

Ventura said on Tuesday that the club could call up a starter as the extra 26th man it's entitled to just for the doubleheader. Erik Johnson last pitched on Aug. 3, so he would be on schedule. The White Sox manager also said the team could use relievers exclusively for Game 1.

• Entering Tuesday's contest, Avisail Garcia was hitting .389 with one homer, one triple and seven RBIs in five games for Triple-A Charlotte since coming to the White Sox in a three-way trade with Detroit and Boston.

• Brian Omogrosso underwent season-ending surgery on Monday to remove loose bodies and shave down a bone spur in his right elbow. Omogrosso, 29, is expected to resume throwing within eight to 10 weeks and is done for the 2013 season. He made 12 relief appearances for the White Sox before being placed on the disabled list retroactive to June 29.
