Williams upset with team's effort

CHICAGO -- White Sox general manager Ken Williams on Wednesday reiterated his displeasure with the effort his team has put forth this season.

"They are underachievers," Williams said before the White Sox played the Minnesota Twins on Wednesday. "We're not playing up to our capabilities. Period."

Earlier this season, Williams said he thought the White Sox could win a second straight AL Central title. But the team is on the verge of being eliminated and in third place with a little more than a week left.

Williams said the White sox must clean up their defense, one that has made 108 errors. Chicago has given up 67 unearned runs this season and has been inconsistent offensively. The White Sox have been shut out 13 times.

Despite the problems, Williams said he expects the entire coaching staff to return although he hasn't discussed it with manager Ozzie Guillen.

He also said he did not know if the White Sox, who have infused their roster this season with younger players, would seek help through free agency or how much money they would have to spend.

Williams had no regrets over the acquisitions this year of Jake Peavy, Alex Rios and Mark Kotsay, even though Peavy just returned to the mound because of injury and Rios has struggled at the plate.

Williams backed up Guillen, who lashed out at his players last week for a lack of effort after a a 14-inning loss in Seattle.

"You give 100 percent effort to close this season with dignity and the best fashion you can and so far we haven't done that," he said. "I know who's quit and who hasn't."
