CHICAGO -- A's right-hander Bartolo Colon, who pitched for the White Sox during the 2003 and '09 seasons, was suspended for 50 games without pay on Wednesday after testing positive for testosterone, a performance-enhancing substance in violation of Major League Baseball's Joint Drug Prevention and Treatment Program.

White Sox designated hitter Adam Dunn expressed disbelief in regard to the latest player to get caught.

"You guys see how many times these drug test guys are here," Dunn said. "I feel like they are here at least once a homestand. I don't want to call you stupid, but kind of look yourself in the mirror. That's pretty dumb."

Manager Robin Ventura was asked if teams should also be penalized when a player tests positive. But Ventura believed that sort of idea was overstepping the punishment phase a bit.

"You can try and limit that with stiffer penalties, but the team can't make that choice for the player," Ventura said. "The players make that choice on their own. Everyone knows the rules. It's surprising."

Cooper, rejuvenated Peavy on same page

CHICAGO -- Jake Peavy and White Sox pitching coach Don Cooper have been working on the exact same page for the entirety of the right-hander's comeback to excellence this season.

There was, however, a moment during Cactus League competition this year in which Peavy endured a rough outing, struggling with his gradual preparation for the regular season, and the two exchanged words in the White Sox dugout. But even that vocal disagreement did no harm to the duo's working relationship.

"We had a little something in Spring Training, and it wasn't a big thing," Cooper told MLB.com. "I just didn't like the way we were handling it that day. Sometimes it's good to get stuff out, and we know we don't have to always agree on stuff. At least at the end of any conversation, we are going to know where we are at."

"It's really been the same since we've got here," Peavy told MLB.com. "Me and Coop have had one time where we have not been on the same page. It's the only time we've ever had words to each other and not talked through anything that we've ever differed on."

If any sort of past working impediment existed between these two knowledgeable pitching minds, it came strictly from Peavy's health issues since joining the White Sox via trade from the Padres on July 31, 2009. Peavy is currently more than two years removed from surgery to reattach his lat muscle and takes a 3.11 ERA over 168 innings and 24 starts into Friday's series opener against the Mariners.

Peavy has tossed a team-best four complete games, recorded a team-high 150 strikeouts and limited the opposition to a .233 average. He's been the sort of top-of-the-rotation hurler general manager Ken Williams and Cooper expected the White Sox would have when the deal was made. It just took the veteran a little while to get back to full strength.

"Now, I think he understands me more than ever," Peavy said of Cooper. "But our relationship as far as professional and then hanging out off the field, it has always been fine in my eyes and we've always been able to talk through things."

"I don't worry about stuff that happens last week, last year, two years ago," said Cooper, who called Peavy a low-maintenance guy in many ways and a pitcher whose "preparation is flawless." "I'm only dealing with today. I really am. And Jake being healthy has just been great. That's all we ever wanted from him. That's all he ever wanted."

Clause in Myers' contract won't sway White Sox

CHICAGO -- When Brett Myers closed out Tuesday's 7-3 victory over the Yankees, it marked the seventh game the right-hander has finished with the White Sox and the 36th game he's finished overall this season. Myers' contract contains a $10 million option that vests for 2013 if he finishes 45 games, changed before the season by the Astros to reflect his shift to the closer's role from starting.

That option, though, won't affect how the White Sox decide to use the hard-nosed veteran down the stretch. If pitching Myers at the end of games is what the White Sox need to do to reach the playoffs, that's the plan they will employ.

"We are bringing Brett in when we need him to come in," White Sox pitching coach Don Cooper said. "I really haven't spoken about that to anybody. I'm glad we got him, and he'll pitch when we feel he needs to pitch, regardless of what else is going on with contracts."

Myers has a 2.93 ERA over 18 games with the White Sox, including four holds. Fifteen of his outings have been scoreless, as Myers helps solidify a young relief crew behind Matt Thornton and Jesse Crain.

"He's a great addition; that's all I know," Cooper said. "He has been good since we've gotten him."

Fresh legs at root of Pierzynski's triples spike

CHICAGO -- A.J. Pierzynski's fourth triple of the season, coming during Tuesday night's 7-3 victory over the Yankees, surpassed his total of three from his previous seven seasons combined with the White Sox.

There's no special reason for Pierzynski's speed increase on the bases, aside from feeling good and incorporating a little more yoga into his offseason workout regimen.

"It's like I've said all year -- I feel great physically," Pierzynski said. "My legs feel as good as they ever have, and I just feel like I'm moving better. I did some agility stuff with [White Sox direction of conditioning Allen Thomas] and in the offseason with my guy, but nothing major. Nothing has really changed a whole lot."
