The Cleveland Guardians muscled their way into first place in the American League Central on Wednesday night, knocking the Chicago White Sox out of the division lead for the first time since early July with a gritty 6-3 win.

Petey Halpin delivered the decisive blow, launching a three-run, go-ahead homer off White Sox reliever Sean Newcomb in the sixth inning to break a tie game and swing momentum firmly toward Cleveland, according to MLB.com's recap of the series finale. The win gave the Guardians a 2-1 series victory over Chicago.

The Standings Flip

Cleveland moved to 78-75 on the season, a half-game ahead of the White Sox at 77-75, according to ESPN's box score from the game. For a White Sox team that had sat atop the division since July 3, the loss marks a significant momentum shift with the season winding down and a playoff spot on the line.

A HALF-GAME SWING WITH THE CLOCK RUNNING OUT.

The late-season rally caps a stretch in which Cleveland has quietly climbed back into contention after trailing for much of the summer, riding timely hitting and a bullpen that has tightened up down the stretch. Chicago, meanwhile, will need to regroup quickly against a schedule that offers little room for further slippage.

What's Next

Both teams now turn to their remaining games with the division lead hanging in the balance and the tiebreaker picture still shifting by the day. With the regular season entering its final stretch, every series carries outsized weight, and Wednesday's result is a reminder of how thin the margin has become in a division that has swapped leaders repeatedly down the stretch. Neither club can afford a prolonged slide with the postseason field about to be set.
