(AP) - Jason Giambi and the sluggish New York Yankees suddenly turned sluggerish.

The Yankees played home run derby Thursday, with Giambi, Johnny Damon, Robinson Cano and Wilson Betemit connecting in a 6-3 victory over the Cleveland Indians.

Mike Mussina (5-3) won his fourth straight start and earned his 255th career victory, holding on for five innings. Joba Chamberlain pitched an easy eighth and Mariano Rivera closed for his ninth save.
