CHICAGO — Jorge Polanco homered for the third time in two days, smacking one of the Minnesota Twins’ three long balls in a 4-1 victory over the Chicago White Sox on Tuesday night.

Polanco led off the fourth inning with his sixth homer of the season after going deep in both ends of a doubleheader Monday.

Kennys Vargas and Eddie Rosario added home runs against rookie Lucas Giolito (0-1) in his White Sox debut. The Twins remained in playoff position with their fifth win in six games.

Giolito, who came to Chicago from the Washington Nationals in an offseason trade for Adam Eaton, allowed six hits and four runs, striking out four.

Rookie Yoan Moncada hustled for a double on a slow ground ball through the infield in the first inning, moved to third base on a fly ball from Jose Abreu and then scored on a wild pitch to open the scoring.

After Polanco’s home run tied it, Vargas started the fifth with a towering shot to right on an 0-2 count to go up 2-1. Rosario hit a two-run home run in the sixth inning.

Minnesota entered with a half-game lead for the second AL wild card and is attempting to hold off a pack that includes the Los Angeles Angels, Seattle, Kansas City and Texas, who all entered Tuesday within two games of the Twins.

Kyle Gibson (7-10) struck out a season-high eight batters over seven innings, allowing one run.
