Ian Happ had three hits, including two doubles, and threw out a runner at the plate from center field to help the Chicago Cubs to an 8-2 victory over the Pittsburgh Pirates.
The Cubs had 13 hits, including eight for extra bases, as the offense broke out after totaling four runs in the first three games of the series.
Happ singled and scored to lead off the game and doubled in the third and eighth innings.
Javier Baez doubled and scored in the second. Jason Heyward singled and was driven in by pitcher Jon Lester's double in the fourth. Baez and Heyward then drove in Anthony Rizzo and Ben Zobrist with back-to-back singles in the fifth as the Cubs piled on against Taillon.
Albert Almora Jr. later added on with a two-run shot in the seventh off receiver Angel Sanchez.
Lester (10-7) worked around traffic in his first four innings but settled down to go six innings with one run and five hits allowed. He struck out five and walked four.
Taillon (7-6) lasted just 4 2/3 innings while giving up six runs and 11 hits. He struck out three and walked just one.
Rookies Josh Bell and Jordan Luplow each had RBIs for the Pirates, who had eight hits but left 11 men on base.
John Lackey (11-10, 4.74 ERA) will begin a three-game series with Milwaukee. He's 6-1 with a 3.83 ERA since the All-Star break.
>>Indians Win 15th Straight
Cleveland jumped all over emergency starter Mike Pelfrey for seven runs in the first three innings and Corey Kluber struck out 13 in seven innings of three-hit ball on Thursday night, helping the Indians win their franchise-record 15th consecutive game, 11-2 over the Chicago White Sox.
Edwin Encarnacion hit a three-run homer in the first inning and Cleveland went deep five times in becoming the first major league team to win 15 straight since the 2002 Oakland A's.
Yolmer Sanchez and Jose Abreu homered in the first for Chicago, but Kluber allowed only one more hit - a fifth-inning single for Omar Narvaez.
The right-hander retired 20 of his last 22 batters on his way to double-digit strikeouts for the 14th time this season and 38th of his career.
Erik Gonzalez hit two home runs and Francisco Lindor and Greg Allen hit one apiece for the Indians. It was the first homer of Allen's career.
The White Sox turned to Pelfrey (3-11), who threw 40 pitches in 2 1/3 innings of relief Tuesday, when Carlos Rodon (shoulder stiffness) was scratched about 15 minutes before game time. Pelfrey allowed seven runs and eight hits in four innings.
Rodon will have his shoulder examined Friday.
Rookie RHP Lucas Giolito (2-1, 2.25 ERA) and Giants LHP Matt Moore (4-13, 5.42 ERA) will square off in the opener of a three-game series on Friday in Chicago.
Giolito won his past two starts, allowing a total of one run and seven hits in 14 innings.
>>Cardinals Blank Padres
Dexter Fowler struck out against BradHand with the bases loaded in the ninth inning, capping the San Diego Padres' 3-0 win over the St. Louis Cardinals on Thursday night.
Hand allowed singles by Stephen Piscotty, Randal Grichuk and Carson Kelly to load the bases in the ninth inning before getting Fowler to whiff on a slider in the dirt. Hand got his 16th save.
Jose Pirela had a run-scoring infield single in the first inning, and that was all the cushion Richard and relievers Craig Stammen, Kirby Yates and Hand needed. Clayton Richard got 11 groundball outs while allowing five hits and striking out five in six innings.
Wil Myers added his 25th homer of the season, a two-run shot in the seventh.
Lance Lynn (10-7) tiptoed around trouble in the first, allowing a run on three infield hits, an error by Alex Mejia and a walk. Pirela's slow roller to third scored Margot after he opened the inning with a hit.
Lynn lasted through the sixth, giving up six hits and three walks, with three strikeouts on 118 pitches.
Luke Weaver (4-1, 2.50) faces the Pirates as St. Louis kicks off a six-game homestand. Weaver is one of five rookies to have double-digit strikeout games this season. His 90 strikeouts through his first 17 career games are the most ever by a Cardinal.
