In a game heard on WHOW, Shane Bieber pitched two-run ball into the eighth inning, and the Cleveland Guardians beat the Chicago White Sox 4-2 on Thursday night for a three-game series sweep.

Cleveland opened a seven-game lead over Chicago in the AL Central with its 15th win in 18 games. The Guardians (83-67) can clinch the franchise's first division title since 2018 as early as Sunday.

Bieber (12-8) earned his fourth straight win. The 2020 AL Cy Young Award winner allowed seven hits, struck out five and walked none in 7 2/3 innings.

Trevor Stephan finished the eighth and Emmanuel Clase handled the ninth for his AL-best 37th save in 41 chances.

Cleveland's pitching staff issued just one walk in the three-game set.

Gavin Sheets homered for Chicago in the eighth. Johnny Cueto (7-9) allowed four runs, three earned, and eight hits in six innings in his third straight loss.

Chicago isn't out of it yet, but it needs lots of wins - and help - down the stretch.

The White Sox (76-74) have dropped three straight and four of six overall.

Cleveland went ahead to stay on Jose Ramirez's sacrifice fly in the third. Steven Kwan hit an RBI triple in the fifth and scored on another Ramirez sacrifice fly, giving the Guardians a 4-1 lead.

The White Sox, who started September with an 8-2 streak but failed to make up much ground on the streaking Guardians, got a run in the first on Eloy Jimenez's RBI single.

Lucas Giolito (10-9, 5.07 ERA) goes against Tigers LHP Eduardo Rodriguez (3-5, 4.35 ERA) on Friday night.
