MILWAUKEE — Jimmy Butler scored 42 points and the Miami Heat staged a second straight stunning fourth-quarter rally before winning 128-126 in overtime on Wednesday night in Game 5 to complete an upset of the top-seeded Bucks in their Eastern Conference first-round playoff series.

Two nights after outscoring the Bucks 30-13 in the final six minutes of a 119-115 victory in Miami, the Heat produced another huge comeback and tied the game on Butler’s layup with half a second left in regulation.

Miami went on to become the sixth No. 8 seed to beat a No. 1 seed. The last time it happened was in 2012, when a Philadelphia 76ers team featuring current Bucks guard Jrue Holiday capitalized on Derrick Rose’s knee injury to beat the top-seeded Chicago Bulls.

The Heat advanced to a second-round series with the fifth-seeded New York Knicks, who completed their 4-1 series win over the Cleveland Cavaliers earlier Wednesday. Game 1 is Sunday in New York.

Bam Adebayo had 20 points, 10 rebounds and 10 assists. Gabe Vincent added 22 points.

Giannis Antetokounmpo had 38 points and 20 rebounds for the Bucks, though he shot just 10 of 23 on free-throw attempts. Khris Middleton added 33 points.
