Responding to a Chicago Sun-Times text question on Saturday regarding whether he's losing patience, Williams answered with a simple "yes." That response doesn't surprise Guillen.
"I don't blame him," Guillen said. "The expectation we have for this ballclub is pretty high. I think we have a ballclub that is better than what we've shown.

"Kenny is very strong with the way he makes moves ... with the way he does his business. He wants to win."
The White Sox entered Sunday's game at Kansas City with a 15-21 record, leaving them seven games back of Minnesota in the American League Central.
"We have a lot of games left," Guillen said. "Meanwhile, those [first 36 games] are going to count in the end. He's entitled to have that opinion."
Guillen reiterated that he isn't worried about his job security if the White Sox continue to stumble.
"I don't care about me," he said. "That's the job. With the coaches, we do everything we can to make those guys better, and I know it. I fired three coaches myself, because I don't think we were on the same page. Right now, if we're going to blame somebody, I'll take the blame.
"If he wants to blow this ballclub away, that's his call. I still believe in this ballclub. We've shown some signs how good we can be, and we've shown some signs how bad we can be."
