LAKE BUENA VISTA, Fla. — Jimmy Butler and the Miami Heat are headed to the Eastern Conference finals.

Giannis Antetokounmpo could only watch.

The fifth-seeded Heat finished off an upset of the NBA’s best regular-season team Tuesday, topping the Milwaukee Bucks 103-94 in Game 5 of their East semifinal series — while Antetokounmpo, the league’s reigning MVP, couldn’t play because of a sprained right ankle.

Butler and Goran Dragic each scored 17 points for the Heat, who won the series 4-1 and will face either Boston or Toronto when the NBA’s final four gets underway next week. It’s Miami’s first time in the East finals since 2014.
