Giannis’ creative triple-double silences Celtics

Giannis Antetokounmpo had already picked up his dribble and spent half of a Eurostep when he realized he had nowhere to go with the ball.

Instead of attempting an off-balance shot or passing to a well-guarded teammate, the two-time NBA MVP flicked the ball high off the backboard, then followed it to the rim for a slam dunk.

“What did I see? I had the ball and I was like, ‘Oh, crap. I’m going to get stuck,’” Antetokounmpo said after recording his second career postseason triple-double to lead the Milwaukee Bucks to a 101-89 victory over the Boston Celtics in Game 1 of their second-round series on Sunday.

“I threw it to the backboard,” he said. “I’m lucky enough that God blessed me with the ability to jump. I had a good jump to go get it again and I was able to finish the play.”

Antetokounmpo had 24 points, 13 rebounds and 12 assists as the defending NBA champions swiped homecourt advantage in the best-of-seven series. (He does not get an assist for passing the ball to himself.)

“That’s just pure talent, just pure instinct,” Bucks coach Mike Budenholzer said. “He’s a great player. He does things that are unique and special and timely. That’s one of those plays where you’re happy he’s on our side.”

Jrue Holiday had 25 points and 10 rebounds, and Bobby Portis had 15 points and 11 boards for the Bucks, who are back at the TD Garden for Game 2 on Tuesday night.

Jayson Tatum scored 21 and Jaylen Brown had 12 points, but the two Boston stars combined to shoot 10 for 31 in the game. Al Horford added 12 points and 10 rebounds for the Celtics, who fired up 50 3-pointers, making 18, and shot 33 percent from the floor as a team.

“Offensively, not our best night. I thought we guarded well enough,” Celtics coach Ime Udoka said. “To lose a 12-point game when we shot so poorly bodes well for us. In a way it’s good to get this dud out of the way, offensively.”

After shutting down Kevin Durant and Kyrie Irving in a four-game sweep of the Brooklyn Nets, Boston couldn’t stop Antetokounmpo — even with green-haired Defensive Player of the Year Marcus Smart shaking off a shoulder injury.

Boston won 26 of its last 32 games in the regular season and was the only team to sweep its first-round playoff series. Now Milwaukee has won four in a row, having won the last three in the first round to eliminate the Bulls in five games.
