Francisco Lindor had an exceptional Monday after a very good Sunday.
Lindor homered twice, including a grand slam, and finished with a career-high seven RBIs as the Cleveland Indians beat the Kansas City Royals 9-3 on Monday night.
On Sunday, he had two doubles and a solo homer in Oakland.
Lindor homered in the fourth after Yan Gomes singled and Jakob Junis hit Tyler Naquin and Rajai Davis with pitches. He added a three-run homer in the sixth to finish Junis' evening.
"One was a changeup and the other one was a slider," said Lindor, who has 23 home runs. "My approach is hit the ball and if it goes out it goes out. It was a good pitch to hit (on the grand slam). I was just trying to get one guy in. I'm not a power hitter. Just get a good pitch to hit and drive it."
Lindor has 17 home runs and 54 RBIs in 54 games against the Royals.
"Just a routine day for him, today and yesterday," Indians starter Corey Kluber said. "He continues to get better, which is kind of scary."
Kluber (12-4), who failed to make it out of the second inning in his previous start at St. Louis, gave up two runs in the first, but little after that. He allowed three runs and seven hits, walked none and struck out five over six innings.
Davis had three hits and scored three runs.
"I got myself into trouble with a couple of hit batters and good teams are going to take advantage of that," Junis said.
Junis (5-10) has lost his last seven starts and is tied with teammate Jason Hammel for most losses in the American League. He has yielded a major league-high 24 home runs, including 12 in his last five starts over 27 innings.
"You worry about his confidence more than anything else," Royals manager Ned Yost said. "Again, it's an easy fix. When you're off the side of the slider, it's gonna be a cement mixer. He started off good, just didn't end that good."
Whit Merrifield homered on Kluber's third pitch for his fourth career leadoff home run. Salvador Perez singled home Mike Moustakas, who had doubled, in an 11-pitch at-bat for the other Kansas City run in the first.
Jorge Bonifacio logged his first RBI of the season in the Kansas City sixth after being suspended the first 80 games for taking a performance enhancing drug.
The Royals have lost 23 of their last 28 games. They are tied with the Baltimore Orioles for the most losses in the majors with 54. They scored four runs or fewer for the 23rd time in the last 24 games.
ROYALS SIGN FIRST-ROUND PICK
The Royals signed right-hander Jackson Kowar, a first-round compensation selection and the 33rd overall pick, to a $2.118.700 signing bonus. He went 10-5 with a 3.04 ERA as a Florida junior.
Royals: LHP Danny Duffy is winless in six home starts this season, going 0-3 with a 6.32 ERA.
