CHICAGO -- If Rangers closer C.J. Wilson should enter Monday night's game against the White Sox at U.S. Cellular Field, he'll expect to hear some boos.

Not only would his appearance indicate that the home-field White Sox are likely losing in the ninth inning, but Chicago fans may not have forgotten about the reaction White Sox manager Ozzie Guillen had the last time Wilson took the hill against the South Siders.

Guillen took exception to Wilson's demeanor on the mound at Rangers Ballpark in Arlington back on July 13, the Sunday before the All-Star break. The White Sox skipper didn't like Wilson's "cocky" reactions after nearly losing his team's four-run lead.

"My comment was: 'I don't care how cocky you're going to be or if you have your own style to pitch,'" Guillen said Monday before the series opener. "I never criticize anybody for having a style. But when you [disrespect] baseball, and you [disrespect] the opposition, I don't think that's class."

Wilson was uninterested in starting a war of words with Guillen, focusing instead on his own performance and that of his teammates.

"Whatever I allegedly did was a week ago," Wilson said. "We've got games to win, that's the concern. I haven't said anything about it. I just like throwing hard and having a mohawk and being an idiot, you know?

"I don't really care about anything, or what anybody else thinks about me or whatever. My team and my manager, those are the people that concern me."

As far as Rangers manager Ron Washington is concerned, the problem is over and done with.

"Ozzie is Ozzie; C.J. is C.J.," Washington said. "You know C.J., and I know Ozzie. I didn't know we had a problem."

Guillen has never shied from wearing his emotions on his sleeve and he, too, believes the "problem" has been resolved.

Wilson seems to have already moved on.

"[Guillen] was obviously upset. During the game I was upset. People get upset," Wilson said. "He's probably an emotional guy. On the field I get to be an emotional guy. It's not like it's rare to have clashes in the game of baseball."

If Wilson takes the mound and hears boos, it won't bother him.

"We're the road team. If I come in, hopefully we'll be winning, so yeah, I expect to be booed," Wilson said. "I like it. I like to get booed."
