MILWAUKEE (AP) — Giannis Antetokounmpo had 31 points and 14 rebounds in just 24 minutes as the NBA-leading Milwaukee Bucks rolled to a 130-94 victory over the San Antonio Spurs on Wednesday night.

The Bucks extended their Eastern Conference advantage to 2½ games over the Boston Celtics as they prepare for a four-game road swing that includes a matchup Saturday with the Western Conference-leading Denver Nuggets.

Antetokounmpo rested the entire fourth quarter and watched the Bucks put the finishing touches on their most lopsided win of the season

Bobby Portis and Khris Middleton added 19 points each for the Bucks, who never trailed. Middleton also had 10 assists, while Portis had 10 rebounds.

Devin Vassell scored 16 points to lead the Spurs.

San Antonio was playing for a second straight night and was missing leading scorer Keldon Johnson for a second consecutive game due to a neck strain. The Spurs also didn’t have usual starter Tre Jones, who was out with a sore left foot after playing Tuesday in a 119-84 loss at New Orleans.

After trailing by 13 in the first quarter, San Antonio got within two points a couple of times in the second period. But after Keita Bates-Diop’s three-point play cut Milwaukee’s lead to 51-49 with 2:41 left in the second, the Bucks outscored the Spurs 15-2 to close the first half.

That spurt included consecutive dunks by Antetokounmpo, the first coming on a putback and the second on an alley-oop from Khris Middleton. Milwaukee capped the run with 3-pointers from Pat Connaughton and Joe Ingles, who beat the buzzer with his shot from the corner in front of the Bucks’ bench.

The Bucks then poured it on in the second half.
