CHICAGO — Not a good day for the Chicago White Sox.

First, Chicago got manhandled by the Minnesota Twins, 20-1.

Then, the White Sox found out they failed to acquire Padres ace Jake Peavy, who turned down a trade.

Joe Mauer hit a grand slam, two doubles and drove in a career-high six runs as the Twins routed the White Sox, 20-1, yesterday, matching Chicago's most-lopsided loss in team history.

"I think a lot frustration came out today," said Mauer, whose Twins had lost the first six games of their road trip before winning big on getaway day. "We had a rough trip. It was nice to get some runs. We kept on saying, 'Keep at it, keep at it.' "

Chicago's only other 19-run defeat in history was a 19-0 loss at Anaheim in 2002.

"We did everything wrong we could do," Chicago manager Ozzie Guillen said. "You name it, we did it wrong."

Michael Cuddyer, Joe Crede and Matt Tolbert also homered as part of a 20-hit Minnesota attack.

Nick Blackburn (3-2) allowed four hits over seven innings to win for the first time at U.S. Cellular Field, where he had been 0-4 with a 5.27 ERA.

Meanwhile, Peavy decided to remain with his longtime team.

The Padres and White Sox had reached an agreement, but needed the 2007 Cy Young Award winner to waive his no-trade clause.

"As of right now, this is the best place for us to be. We made that decision for the time being," Peavy said before last night's game against San Francisco.

"It's been a crazy 24 hours," he said. "I don't want to be any kind of distraction to the team. We're playing as well as we possibly can, winning five in a row and I've got a big game tomorrow night vs. the Chicago Cubs."

Peavy, who turns 28 later this month, is 3-5 with a 3.82 ERA. He made his major league debut with San Diego in 2002.

He and his wife have three sons, all under the age of 8.

Several reports said the White Sox would've sent top pitching prospect Aaron Poreda and young left-hander Clayton Richard to San Diego as part of the package for Peavy.

NOTES

Reds: Right-hander Edinson Volquez went on the 15-day disabled list with a sore back. He developed back spasms during a game Saturday in San Diego. Volquez is 4-2 with a 4.25 ERA in eight starts.

Also, Reds first baseman Joey Votto has an ear infection that should clear up in a few days with medication, doctors concluded yesterday. Votto had a series of tests in two cities after he got dizzy spells during a West Coast trip last week.

Trade: The San Diego Padres have acquired outfielder Tony Gwynn Jr. in a trade that sent outfielder Jody Gerut to the Milwaukee Brewers. Gwynn, who had been with Triple-A Nashville, got the news of the trade in a call from his Hall of Fame father, who played for the Padres for 20 seasons and is now San Diego State's baseball coach.

Rangers: Texas right-hander Vicente Padilla (3-2, 4.71 ERA) is headed to the disabled list because of a strained shoulder muscle.
