The Indians and Royals aim to continue their runs of good fortune at the other's expense on Friday when they open a three-game series in Cleveland.
Cleveland brought out the brooms on Thursday and recorded its fifth straight win and 11th in 13 contests with a 6-3 victory over Detroit. The win moved the Indians a season-best 15 games over .500.
Jose Ramirez belted a go-ahead two-run homer in the sixth inning and drove in three runs. The 26-year-old enters the series opener against Kansas City with a 10-game hitting streak, during which he is 15-for-41 with four homers, 12 RBIs and 10 runs scored.
"Even if Jose is being the hottest one right now with home runs, we're still putting up a good amount of runs," second baseman Jason Kipnis said. "It's not all him. It's coming from (Nos.) one through nine in the order. Guys are having good at-bats.
"It may not be pretty. It may not be what you want all the time. But we're doing whatever we can to get on base and get guys in."
Cleveland avenged a sweep at the hands of Kansas City in April by winning two of three from the Royals in late June and posting a sweep on July 2-4.
Like the Indians, Kansas City completed a four-game sweep on Thursday with a 6-5 victory over the Chicago White Sox. The win was the Royals' sixth in seven games since the All-Star break.
"We're playing really good ball right now," Kansas City right-hander Brad Keller said. "The offense is alive and killing it right now. The starters and relievers are doing their job. The break helped us, I think."
The Royals are hitting .330 as a team and scored 49 runs in seven games since the All-Star break.
"The vibes in the clubhouse got a lot better," Kansas City reliever Tim Hill said. "It's definitely a different energy, and it's good."
Bieber returned from capturing Most Valuable Player honors in the All-Star Game with a no-decision versus Minnesota on Sunday.
The 24-year-old also received a no-decision against Kansas City on June 25 despite permitting two earned runs in 5 1/3 innings.
Bieber owns a 2-0 mark with a 5.40 ERA in three career starts versus the Royals, although Lucas Duda (3-for-7, two homers) and Merrifield (3-for-9, home run) have gotten their licks in on the hurler.
Left-hander Mike Montgomery (1-2, 5.67 ERA) will make his debut with Kansas City after being acquired from the Chicago Cubs on Monday.
Montgomery last pitched on July 2, allowing one run on two hits in 3 1/3 innings in a no-decision against Pittsburgh.
Francisco Lindor is 2-for-5 with a double in his career against the 30-year-old Montgomery, who has yet to record a decision with a 6.75 ERA in five career appearances against Cleveland.
