Giannis Antetokonmpo played like an MVP for the final three quarters and the Celtics simply could find an answer for the athletic forward without Marcus Morris or Gordon Hayward available. The All-Star scored a game-high 37 points and added 13 rebounds to help the Bucks spoil the Celtics home opener with a 108-100 victory.
Boston led for the majority of the second half after rallying from an five-point halftime deficit early in the third quarter but their offense lost steam in the final 10 minutes of the game. Kyrie Irving resorted to some isolation ball on a night his shooting wasn't falling 17 points (7-of-25 from field) and it particularly hurt in the second half (2-of-13 after intermission) as the hosts failed to keep pace with a high-powered Bucks offense. Milwaukee outscored Boston 32-20 in the final frame.
Jaylen Brown led the C's for the second straight game with a team-high 18 points before fouling out with two minutes remaining.
The 0-2 Celtics hit the road to try to earn their first win of the season in Philadelphia on Friday.
