Lindor homered in the ninth inning of Cleveland's 5-1 loss Monday to the Kansas City Royals, who extended their winning streak to a season-high six games.
The Indians have lost three straight but still lead the American League Central by 14 games. Their magic number to clinch the division was trimmed to 12 after Minnesota's loss to Houston.
"Our energy is down," Lindor said. "I don't [know] why. Personally, my energy is down. We're at that point in the season where guys are dragging their feet a little. We have to go back to playing the Tribe Way and not taking any pitch for granted. We'll be fine."
"It's no fluke," O'Hearn said. "Guys are going out, trying to win every day. Everyone is playing really well."
Junis (8-12) gave up a two-out single to Lindor in the third and a leadoff single to Yonder Alonso in the fifth. The right-hander hit a batter, walked none, struck out six and retired his last nine hitters.
Junis was 0-2 with a 9.82 ERA in his first two starts against the Indians this season.
"Being in the division, these teams see my slider a lot," he said. "Using my heater more was definitely the difference."
Brian Flynn pitched a scoreless eighth and Wily Peralta began the ninth with a 5-0 lead. Lindor homered with one out, Michael Brantley singled, and Peralta walked Jose Ramirez and Edwin Encarnacion on eight pitches.
"That was a great play by Whit, a great play," manager Ned Yost said. "That's why you bring Timmy in, to get a ground ball."
Lindor has 30 homers this season. He joins Ramirez, who has 37 home runs, as the first pair of switch-hitting teammates in major league history to each have 30 or more homers in a season.
Adam Plutko (4-5) gave up three homers and allowed four runs in six innings. The right-hander had a career-high eight strikeouts.
Kansas City took two of three from Cleveland at Kaufmann Stadium last month, and Junis made certain that trend continued. He retired the first eight batters before hitting Greg Allen with a pitch in the third. Lindor sent Allen to third with a single, but the inning ended with an out on the bases.
Lindor broke for second and was caught in a rundown when catcher Cam Gallagher threw to shortstop Adalberto Mondesi. The rundown continued until Allen finally broke for home, and Merrifield threw to Gallagher, who applied the tag.
Josh Donaldson hit a grand slam in Triple-A on Monday after the Indians placed him on the disabled list to give him more time to rehab a calf injury in the minor leagues. Donaldson, playing for Columbus, also walked and lined out against Toledo. Donaldson, acquired from Toronto on Friday, will work out with the Indians on Tuesday and continue his rehab assignment for Double-A Akron in the Eastern League playoffs this week.
"That was good," Indians manager Terry Francona said. "It sounded like everything else went well, too, and he made all the plays."
HEAR THE BUZZ
The Cleveland National Air Show, held at a nearby airport, ended Monday. Players and fans turned their attention to jets that flew around the ballpark in the early innings.
FEEL THE HEAT
Temperatures for the three-game series will be near 90 degrees each day, a stark contrast from the first time the Royals were in town. The game-time temperature of 32 degrees on April 8 set a Progressive Field record.
Royals: C Salvador Perez (sprained left thumb) sat out his fifth straight game, but Yost said he is improving and remains day-to-day. The six-time All-Star last played on Aug. 28 against Detroit.
Royals LHP Danny Duffy (8-11, 4.72 ERA) takes on Indians RHP Mike Clevinger (10-7, 3.17 ERA) in the second game of the series. Clevinger has made three starts against Kansas City this season, going 1-0 with a 2.57 ERA.
