BOSTON (AP) - Kevin Youkilis hit his first homer at Fenway Park as a visitor, driving a three-run shot over the Green Monster to lead the Chicago White Sox to a 7-5 win over the Boston Red Sox on Tuesday night.

It's been less than a month since Boston traded one of its most popular players to Chicago and the Fenway fans cheered "Yooouk!" loudly for the second straight night - even as he rounded the bases to put Chicago up 6-2 with his homer off of Jon Lester (6-6) in the fourth inning.

The White Sox won for the eighth time in 11 games and are 10 games above .500 (50-40) for the fourth time this season.

Philip Humber (4-4) made his first start in a month and settled down after allowing two runs in a shaky first inning.
