MILWAUKEE — The Milwaukee Bucks started their 4/20 blowout of the Toronto Raptors early with Khris Middleton scoring bucket after bucket.

Thon Maker got involved with a forceful dunk. Off the bench, Greg Monroe did what he’s done all season: score and rebound. Michael Beasley fired up the crowd with two three-pointers.

The story of Milwaukee’s 104-77 victory against Toronto in Game 3 on Thursday wouldn’t be complete without a word from Giannis Antetokounmpo, who did Giannis Antetokounmpo things.

He had 19 points, eight rebounds, four assists, two blocks and two steals.

Middleton had 20 points and seven assists, and Monroe scored 16 points and collected seven rebounds as the Bucks took a 2-1 series lead. Game 4 is Saturday (3 p.m. ET, TNT).

“They ambushed us,” Raptors coach Dwane Casey said. “There’s no aspect of our game that we executed whatsoever.”

The Bucks shot 52.7% from the field, and 52.2% on three-pointers, building a 57-25 lead in the second quarter. Unlike the Indiana Pacers, who squandered a 26-point lead against the Cleveland Cavaliers in Game 3 on Thursday, the Bucks didn’t let up. They led 95-64 with 5:40 left in the fourth quarter.

While it’s easy to be smitten with offensive fireworks – who doesn’t like 13 points from Beasley and 11 from Maker – Milwaukee’s defense bludgeoned Toronto’s offense with pressure and length. The Bucks have made it difficult for Toronto to score at the rim.

Raptors All-Star guard DeMar DeRozan, who finished fifth in scoring at 27.3 points per game, missed his eight field goal attempts, scoring his eight points from the foul line. The last team to hold DeRozan to zero made field goals in a game? The Bucks in 2015.

“We’ve got to be better – myself, Kyle (Lowry), us as a team,” DeRozan said. “We have to get stops. We can’t have them shooting 53%.”

Toronto shot 23.3% in the first half, including 2-for-11 on three-points and scored just 30 points. The Raptors weren’t much better in the second half and now must regroup, especially offensively.

“It starts with us and myself,” Casey said. “As a staff, we have to do a better job of finding ways for openings and space for us to score. We went back to not moving the basketball like the way we did in Game 1. … Our disposition isn’t what it should be and what is has been. Again, it’s a quick turnaround. It’s one game. We’ve been in this situation before.”
