Red Sox 5, White Sox 2
CHICAGO — David Ortiz hit his 509th home run to power the Red Sox. Ortiz's two-run shot to rightfield off Carlos Rodon in the fifth inning tied him with Gary Sheffield for 25th all-time. It was his sixth homer of the season and 451st with Boston, one off Carl Yastrzemski's club mark. Ortiz added an RBI single in the seventh against Zach Duke, and embattled Clay Buchholz was sharp over seven innings in Boston's fourth win in five games.
