LOS ANGELES (AFP) — Giannis Antetokounmpo sparked the Milwaukee Bucks over Oklahoma City in a Sunday showdown of National Basketball Association contenders while James Harden lost his first meeting with Philadelphia since the 76ers traded him.

Antetokounmpo scored 30 points and grabbed a season-high 19 rebounds to lead Milwaukee over visiting Oklahoma, 118-93.

Khris Middleton added his second career triple-double — and first since 2018 — with 11 points, 10 rebounds and 10 assists for the Bucks, whose defensive effort kept the Thunder to a season-low point production on 37.1 percent shooting.

"It was cool," Middleton said of his rare feat.

"My teammates were knocking down a lot of shots for me. It was a good win against a good team. But we've got to keep building on this for the rest of the season."

Oklahoma City fell to 49-21, tumbling a half-game behind Denver for the Western Conference lead and a half-game ahead of third-place Minnesota.

Milwaukee improved to 46-25, second in the Eastern Conference by three games over Cleveland.

Oklahoma City's Shai Gilgeous-Alexander scored only 12 points, his second-worst game total of the season. It snapped a 29-game run of at least 20 points a game for the NBA's No. 2 overall scorer, who is just ahead of Antetokounmpo.
