A late scoring explosion from James Harden propelled the Brooklyn Nets to a 100-95 victory over the Detroit Pistons.
After trailing through most of the game, Detroit's offence finally clicked into gear in the fourth quarter as the Pistons rallied behind Jerami Grant to stay within earshot of snatching an upset win.
However Harden – who also finished with 10 rebounds and 10 assists – was too strong down the stretch, scoring 12 of his 24 points in the last quarter to help the Nets hold on for a five-point win.
Kyrie Irving added 18 points for Brooklyn, while Grant finished with 22.
Westbrook scored 42 points to Antetokounmpo's 33, but the Wizards were ultimately not able to keep up with the Bucks all the way to the final buzzer.
The win keeps Milwaukee within two games of the Philadelphia 76ers at the top of the Eastern Conference.
Malcolm Brogdon scored 25 points to lead the Indiana Pacers to a 122-111 victory over the Phoenix Suns.
