Kevin Youkilis walked up to the plate before his first at-bat and the familiar chant of "Yooooouk" echoed throughout Fenway Park. He briefly said something to Boston catcher Jarrod Saltalamacchia before taking off his helmet and turning to all corners of the ballpark to acknowledge the standing ovation, which lasted more than a minute. Youkilis then lined a single to center off Aaron Cook and scored with some aggressive baserunning. The former Red Sox star, traded to the White Sox last month, headed to third on Adam Dunn's groundout when the bag was left uncovered. He dashed home when first baseman Adrian Gonzalez threw the ball into left field for an error. It was the sort of hustle play Red Sox fans grew accustomed to from Youkilis, and they chanted his nickname again. And it was Chicago's only run in a 5-1 loss to the Red Sox on Monday night.
