CHICAGO _ Ben Zobrist's seventh career hit against White Sox starter Chris Sale, an RBI single with one out in the third, put the Cubs ahead to stay Thursday during a 3-1 victory against the White Sox.
Addison Russell added an insurance run with an RBI groundout in the eighth inning of a game dominated mostly by Sale, Cubs starter John Lackey and a host of relievers in front of 41,157 at Wrigley Field.
The Cubs' victory means the season series ends in a split, with each team winning both games at their home parks.
The White Sox's Melky Cabrera and the Cubs' Kris Bryant each hit RBI doubles in the first inning at to leave the score tied 1-1.
Sale started for the White Sox after serving a five-day suspension for cutting up some of the team's 1976 throwback jerseys before his scheduled start Saturday.
He allowed two runs, six hits, three walks and struck out four in six innings.
Jason Heyward, who is 5-for-45 in his last 13 games, was not in the Cubs' starting lineup but entered as a defensive replacement in the ninth.
Lackey retired 10 White Sox in a row from the second inning through the fourth. He allowed a run, four hits a walk and struck out four in six innings.
