Colson Montgomery hit a go-ahead homer in the eighth inning off Tim Herrin for the second of his two RBIs, helping the Chicago White Sox beat the Cleveland Guardians 3-1 on Saturday night. Chicago reclaimed first place in the AL Central by percentage points over the Guardians, who won the first two games of the series on walk-off hits. Montgomery, who leads all shortstops with 22 homers, led off the eighth with a 402-foot shot to center off Herrin (1-4). It came on the first anniversary of his major league debut and gave the White Sox a 2-1 lead. All-Star Miguel Vargas tacked on a sacrifice fly against Matt Festa in the ninth, scoring Tristan Peters with an insurance run.
