The Red Sox are not going to make some unforeseen postseason surge.

But at least they can still play a winning brand of baseball.

Mike Napoli’s two-run home run in the fifth inning yesterday put the Sox ahead to stay for a 5-4 victory against the Cincinnati Reds, their third win in a row and their first such streak since a four-game run coming out of the All-Star break.

The two-game sweep of the Reds sent the Sox home with a 5-3 record on their road trip. This season, that’s a tremendous mark.

“It was nice, a winning road trip,” Napoli said. “We’re playing better baseball. I feel like there were a couple games we could’ve came away with, too. We’re playing better baseball, the young guys are learning and we’re playing the game the right way. That’s what we need.”

With the Red Sox trailing 3-2 entering the fifth, the heart of the order came through for the third game in a row.

Yoenis Cespedes, the hero in the previous two games with go-ahead homers, hit a single to left field to bring in Brock Holt (leadoff double), then scored on Napoli’s opposite-field blast to right.

When his turn to bat came back around in the seventh, Cespedes exited with a bruised right hand and Will Middlebrooks pinch-hit.
