The last thing the Reds wanted after Thursday’s 14-inning marathon loss was a long game – and a loss.

Jay Bruce obliged on both counts. He hit an opposite field home run in the 10th inning to lift the Reds to a 4-3 walk-off win over the Milwaukee Brewers before a crowd of 35,138 at Great American Ball Park Friday.

“Yesterday was a little disheartening,” Bruce said. “We were there a long time. We used a lot of people. Frankly, everyone was a little tired today. It was good to win regardless. Bronson (Arroyo) pitched a great game. It was good to at least salvage it a little bit for him.”

The homer was a high shot that just made it into the left-field seats.

“I didn’t know if I got enough or not,” Bruce said.

It was Bruce’s 11th homer of the year. It was his fifth career walk-off home run.

Arroyo went 72⁄3 innings and allowed three runs (two earned) on 12 hits. He walked one (the last batter he faced) and struck out five. He was an out away from getting out of the eighth when Martin Maldonado homered to tie it.

“I knew I needed one more out,” Arroyo said. “I knew he’d turn it over to (Aroldis) Chapman, even though I felt strong. That was as good as I felt all year for that deep in a ballgame. I felt I could have thrown four more innings.

“Sometimes you win those. Sometimes you get burned. It was a 2-0 breaking ball. I didn’t want to put myself in a position of putting another guy on base and having to face a lefty. I wanted to go after him. But he just got the ball out of the park.”

The Reds took a 1-0 lead in the first. Shin-Soo Choo led off with a double to right-center. Derrick Robinson popped to shallow right. Choo stole third with Brandon Phillips at the plate.

The Brewers brought the infield in. Phillips bounced one over short on the ninth pitch of his at-bat to drive Choo in. Bruce worked an eight-pitch walk, but former Red Kyle Lohse got out of it from there.

The Reds added a run in the second. Zack Cozart led off with a single to right. Ryan Hanigan followed with a smash that got through shortstop Jean Segura for a hit. Arroyo bunted Hanigan to second.
