The White Sox acquired three-time all-star Kevin Youkilis and cash considerations from the Boston Red Sox in exchange for infielder Brent Lillibridge and right-handed pitcher Zach Stewart on Sunday.
Youkilis, 33, is a career .286 hitter with 133 home runs, 239 doubles, 563 RBI and 594 runs scored over nine seasons with Boston. He is hitting .225 with four home runs and 13 RBI in 41 games this season. He was on the disabled list from May 2-21 with lower back tightness.
Lillibridge, 28, is hitting .175 with no home runs, two RBI and seven stolen bases in 48 games. A versatile player who can play all three outfield positions and all four infield spots, he batted .217 with 15 home runs and 50 RBI over three-plus seasons in Chicago. Lillibridge was due to bat for the Sox during the 10th inning of Sunday's game against the Brewers, but was lifted for pinch hitter Eduardo Escobar, who delivered the game-winning hit in a 1-0 Sox victory.
Stewart, 25, was sent to the AAA Charlotte on Tuesday after going 1-2 with a 6.00 ERA over 30 innings with the Sox. He was acquired from Toronto last July with pitcher Jason Frasor in the trade for pitcher Edwin Jackson and infielder Mark Teahen.
The Sox will receive about $5.5 million from the Red Sox to cover the majority of Youkilis' salary.
General manager Ken Williams signed veteran Orlando Hudson in late May as a stopgap measure to replace the injured Brent Morel at third, but Hudson has hit well below .200 and had his ups and downs transitioning from second base to third.
"We owe it to our fans and the men in that clubhouse in uniform to try to exhaust ourselves to be the best team we can possibly be," Williams said.
"He's a good teammate, plays hard,'' White Sox manager Robin Ventura said of Youkilis. "He's a pro and I think he'll fit in just fine.''
