Giannis Antetokounmpo scored 36 points and Kevin Porter Jr. added 24 to help the Milwaukee Bucks win an overtime battle against the host Miami Heat 121-115 on Saturday night.

Antetokounmpo had a triple-double for Milwaukee (43-34), which won its third in a row, with 15 rebounds and 10 assists. Porter finished with 12 rebounds and eight assists.

Miami (35-42) lost its second straight game after winning six in a row. Bam Adebayo led with 31 points and 12 rebounds, while Alec Burks added 24 points.

Miami gained the early edge as Adebayo dominated the first. The big man scored half of Miami’s points in the quarter as the Heat took a 30-22 lead into the second.

The Bucks got a boost with 20 points from their bench in the second. Milwaukee took a slim lead and eventually went into halftime tied at 57.

The game remained tightly contested throughout the second half. Miami took a lead as high as six with 4:30 to play thanks to a 7-0 run, but that was the largest margin from that point on.

Antetokounmpo had an open look from mid-range that would have given Milwaukee the lead with less than a second to play, but it rimmed out and Adebayo didn’t get a shot off with just 0.7 seconds on the clock at the end of regulation.

In overtime, the back-and-forth nature of this one continued. Ultimately, Porter and Antetokounmpo came through for the Bucks.

Porter tied the game at 115 with a layup and dished it to Antetokounmpo on a dunk that gave Milwaukee the lead. Then, with 11 seconds to go, Porter’s tough layup in traffic put the game away.

There were 12 lead changes and 15 ties in the game.

Milwaukee won its fourth in a row over Miami and completed the four-game season series sweep. It is the first time the Bucks have swept the series in 10 seasons.
