Teoscar Hernandez hit a three-run homer, Vladimir Guerrero Jr. also went deep and the Toronto Blue Jays beat the Chicago Cubs 5-3 on Tuesday night.

Kevin Gausman pitched six solid innings to win his second straight decision as the Blue Jays won back-to-back games after losing their previous three. Toronto is in position for an AL wild card.

Guerrero finished with three hits and two RBIs.

Back in the lineup after sitting out Monday because of a sore left foot, Hernandez homered for the first time since Aug. 18 at New York.

Willson Contreras and Christopher Morel hit solo home runs for the Cubs, but Contreras left in the sixth inning after aggravating his sore left ankle. Contreras limped around the bases after his fourth-inning homer.

Gausman (10-9) allowed two runs and five hits, walked one and struck out nine, including five straight Ks in the second and third innings.

Facing his former team for the first time, Cubs right-hander Marcus Stroman allowed one run and three hits in five innings, leaving with a 2-1 lead.

Contreras is the first catcher in Cubs history to hit 20 or more home runs in consecutive seasons.

Mitch White (1-4, 4.24 ERA) starts for Toronto in Wednesday's series finale. The Cubs have not named a starter.
