NBA champions the Milwaukee Bucks suffered consecutive defeats after being upstaged by the San Antonio Spurs 102-93.

Giannis Antetokounmpo posted a double-double of 28 points and 13 rebounds, but the Bucks still suffered back-to-back losses on Saturday.

The Spurs (2-4) trumped the Bucks (3-3) on the road in Milwaukee thanks to point guard Dejounte Murray, who scored 16 of his 23 points in the final period.

Murray entered the contest having put up 44 points, 22 rebounds and 23 assists over his previous two games – the only Spurs player in the last 30 seasons to have had at least 40 points, 20 rebounds and 20 assists over a two-game span, according to Stats Perform.

"Obviously, it's a good win against the NBA champions," Spurs head coach Gregg Popovich said after the Bucks were again without Jrue Holiday due to an ankle injury. "They were missing a pretty big piece tonight but it happens to all of us."

76ers gain some revenge as Heat sizzle

Facing the Atlanta Hawks for the first time since being surprisingly eliminated in last season's Eastern Conference semi-finals, the Philadelphia 76ers routed their rivals 122-94. Tobias Harris fuelled the 76ers with 22 points and 11 rebounds, joining Joel Embiid as the only 76ers players this season with 20-10 games.

The high-flying Miami Heat finished one short of setting a new franchise record after sinking 21 three-pointers in their 129-103 victory at the Memphis Grizzlies. Jimmy Butler led the way with 27 points.

Reigning MVP Nikola Jokic starred with 26 points and 19 rebounds as the Denver Nuggets outlasted the Minnesota Timberwolves 93-91.

Double-doubles from Deandre Ayton (17 points and 12 rebounds) and Chris Paul (16 points and 10 assists) helped last season's NBA Finals runners-up the Phoenix Suns beat the Cleveland Cavaliers 101-92.

Jazz taste defeat

The Utah Jazz were the last unbeaten team remaining having opened their season 4-0, until the new-look Chicago Bulls spoiled the party with a 107-99 win.
