CLEVELAND: The Indians dominated the overmatched Chicago White Sox 9-1 on Wednesday at Progressive Field, notching a series sweep and their fifth consecutive win overall.

Corey Kluber (8-2) cruised all day, allowing only three hits and striking out 10 in six scoreless innings. It was the 43rd double-digit-strikeout game of his career and the fourth this season, and he reduced his ERA to 2.02, the third lowest in baseball.

The Indians (29-25) gave Kluber a 2-0 lead in the first inning and increased it to 9-0 by the fourth, putting the game out of reach early against the rebuilding White Sox (16-37).

“Anytime you can save anybody’s bullets, that’s really a good thing,” Indians manager Terry Francona said. “It was nice that we were able to get [Kluber] out after six. He doesn’t have to go out and grind through because we rely on him so much. He was going to get an extra day this time anyway, but it worked out really well.”

Kluber has dominated the American League Central this season. After Wednesday’s outing, he’s 4-0 with a 0.33 ERA in four starts against teams in the division.

Jose Ramirez went 2-for-4 and homered for the second consecutive day after false rumors hit the internet indicating he had failed a test for performance-enhancing drugs. He now has 17 home runs this season, one off the major-league lead of 18 by the Los Angeles Angels Mike Trout entering Wednesday’s games.

After Ramirez’s fourth-inning home run off White Sox reliever Chris Volstad, who took over from starter Reynaldo Lopez (1-4) in the Indians’ five-run third, Edwin Encarnacion followed with another homer to extend the Indians’ lead to 9-0. It was Encarnacion’s 13th home run of the season.

Melky Cabrera put together his most productive day with the Indians, going 1-for-3, including a two-run double in the third, and three RBI. Erik Gonzalez filled in for Francisco Lindor, who received the day off to rest, and went 1-for-3 with an RBI.

“It’s nice to have a game like today where you can let the guys [relax a bit],” Francona said. “Because they’ve been grinding and we got a big series now coming up, but just to be able to have some room where if somebody does make a mistake … it doesn’t cost you a game.”

The offensive outburst marked the fifth consecutive game in which the Indians have scored at least seven runs, the longest such streak since August 2008. They also lead the league with 170 runs scored in May as of the conclusion of their game.

“The offense has been doing really well for a long time, swinging the bat really well,” Kluber said. “If we can pitch well to support that, obviously, it makes for a good recipe to win ballgames. We’ve been able to do that for the last five games.

“I think that’s any team’s best chance to win games — score runs and don’t let them.”
