White Sox scout Zack Greinke

CHICAGO -- Jake Peavy, whom the Chicago White Sox acquired in a blockbuster deal before the 2009 trade deadline, said he's well aware of Ken Williams' reputation for bold moves, and wouldn't be opposed to Williams pulling off another one by acquiring the Milwaukee Brewers' Zack Greinke.

The Sox had one of their top talent evaluators, scout Bill Scherrer, watching Greinke defeat the Philadelphia Phillies on Monday night.

"I think we would all welcome a pitcher of that caliber," Peavy said Wednesday after notching his ninth win of the season. "We can only let the next week play out and respond to whatever happens.

"You never know what Kenny will do. At the same time, we believe in the guys we have, and if this is all we have to get it done, we believe we can."

The win Wednesday kept the Sox tied with the Detroit Tigers atop the American League Central.

The market for quality starters is never robust, but it shrunk further with the recent news of Cole Hamels' extension and the Astros moving Wandy Rodriguez to Pittsburgh.

"That is out of our control," Adam Dunn said. "We just have to do the best we can with what we have. We like what we have because it has put us in the position we are in now. You would not be opposed to getting someone (like Greinke) but that is not my job."

As far as Chicago's prospects go, the organization has good young pitching to offer at the Single-A and Double-A levels if the Brewers want to go that route in a trade.

Williams has declared any pitcher he picks up must be tough enough to handle a big market like Chicago and handle American League lineups.

"(Williams) is certainly not afraid to pull the trigger on a deal at anytime," Alex Rios said. "It will be interesting to watch what he does before the deadline."

Greinke, who can declare for free agency at season's end, will be costly to re-sign on the open market, and could turn out to be a rental player.
