Middleton finished with a game-high 27 points and downplayed the importance of his go-ahead basket.
“I was just trying to get to the rim and make a play happen,” Middleton said.
Milwaukee scored 20 points off 16 Dallas turnovers, including that Middleton bucket, which came on a deflected pass from Dirk Nowitzki.
“A bad turnover on my part there. We’re up one,” Nowitzki said. “I saw Zaza [Pachulia] flash in there and thought I could get it to him in the lane. He could swing it maybe for a good shot on the weak side. Henson’s long and he got his arm on it.”
Deron Williams tried to give Dallas a chance at the buzzer, but missed the mark. The good news for the Mavericks was that former Badger Devin Harris posted a career-high 19 bench points.
Middleton scored 17 points in the half, making 7-11 shots from the field, and Henson added eight in the second quarter.
