(CHICAGO) – Willson Contreras celebrated a very special anniversary with an impressive all-around show. Contreras homered twice and drove in five runs, and the Chicago Cubs handed Lucas Giolito his first loss since April by downing the Chicago White Sox 7-3 on Wednesday night. David Bote also connected to help the Cubs bounce back from a tough loss to their crosstown rivals in their first meeting of the season. Jon Lester (6-5) allowed two more homers, but worked into the sixth inning to improve to 3-1 in June. Contreras had his sixth career multihomer game on the third anniversary of his first plate appearance in the majors. He also cut down speedy Tim Anderson trying to steal third after he led off the fifth with a double. Trying for his ninth win in a row, Giolito (10-2) showed flashes of the dominant stuff that put him in the mix to start next month's All-Star Game in Cleveland. He struck out Kris Bryant three times and fanned Kyle Schwarber twice on a rainy, windy and unseasonably cold night at Wrigley Field. Giolito allowed six runs and seven hits, struck out nine and walked three in his first loss since April 6 against Seattle. The 6 foot 6 right-hander went 9-0 with a 1.67 ERA in his previous 11 starts. Leury Garcia homered on Lester's first pitch, and James McCann also went deep for the White Sox.
