Another day, another nail-biter of a win for the Cubs at Wrigley Field.

For the second straight night, the Cubs walked off the Indians — this time by a score of 3-2 in 10 innings.

After Jason Adam stranded the free baserunner in the top of the 10th inning, Javy Báez yanked an 0-2 pitch into left field for a two-out, walk-off hit to send the Cubs home winners.

The Cubs’ win ensured a season sweep of the playoff-hopeful Indians, going 4-0 against Cleveland in 2020.

“We continue to do a lot of things well. I think there’s still room for improvement in areas, but when you get these late wins — the walk-off type wins — it just feels really good,” David Ross said. “It’s a nice momentum going into the off-day, sweeping the series against Cleveland here was really nice. … It feels like we’re getting to a place where everybody is where they want to be.”

It was a hard-fought game that also included a 7-minute, 10-second drone delay.

Jon Lester got the start for the North Siders and — just like he did in Game 5 of the World Series — kept the Indians’ bats at bay at Wrigley Field. The veteran lefty gave up some hard contact, but limited the damage to 2 runs on 4 hits over 5 innings.

The Cubs bullpen threw 5 shutout innings, striking out 7 and allowing only 1 hit in that span.

“I think the guys we’ve called upon have done a really good job for most of the year. Seems like a long time since I had real worries down there [in the bullpen],” Ross said. “Jason Adam — a big outing after not pitching for a while was real nice. … Really good all-around game and the bullpen really keeping it close and doing a really good job.”

The Cubs plated a run in the 2nd inning on Jason Heyward’s RBI single and added another in the 4th on Cameron Maybin’s run-scoring hit.

The Cubs threatened to take the lead in the 7th inning when Maybin singled and Nico Hoerner doubled to begin the frame. But Cleveland relief ace James Karinchak (17.1 K/9) entered the ballgame and did what he does best, getting Ian Happ and Kris Bryant to whiff. After an intentional walk to Anthony Rizzo, Willson Contreras grounded out to end the rally.

In the 10th, Happ led off as the free baserunner and Bryant smacked the first pitch of the inning into center for a hit to advance Happ to third base. Rizzo was intentionally walked and after back-to-back strikeouts, Báez came through in the clutch.

The Cubs are now 30-20 on the season and carry a 5.5-game lead in the division over the second-place Cincinnati Reds.
