Kevin Durant led the rampant Nets to a 39-point win in New York, while the Phoenix Suns won Monday’s other match.
Despite again missing James Harden – who left in the first minute of Game One with a hamstring strain – the Nets embarrassed the Bucks and their dual MVP Giannis Antetokounmpo with a searing performance that leaves them halfway from a place in the semi-finals.
The home side stormed into a 36-19 lead at the first break, led 65-41 at half time, and maintained their pressure in the second half to record the biggest play-off victory in the team’s history.
Kyrie Irving contributed 22 points for Brooklyn while Bruce Brown – filling in for Harden – and Joe Harris scored 13 points each.
Antetokounmpo was Milwaukee’s top scorer with just 18 points, complemented by 11 rebounds, while Khris Middleton finished with 17 points.
Game Three is on Thursday in Milwaukee.

Chris Paul contributed 21 points and 11 assists for the Suns, Mikal Bridges top-scored with 23 points while Devin Booker (21 points) and Deandre Ayton (20 points and 10 rebounds) also played big parts in the win.
