Milwaukee Bucks star Giannis Antetokounmpo is one of the hardest players in the NBA to block because of his height and incredible length. Boston Celtics center Al Horford defied the odds Sunday in Game 1 of his team's Eastern Conference semifinals series by blocking Antetokounmpo not once but twice in the same sequence.

The last block was an emphatic highlight-reel swat. Check both of them out in the video below:

At the time of this play in the third quarter, Horford had five blocks in the game and four of them came at the expense of Antetokounmpo. Boston had eight blocks overall.

Antetokounmpo averaged 27.7 points, 12.5 rebounds and 5.9 assists per game during the regular season. He then averaged 26.3 points, 12 rebounds and 3.5 assists per game in Milwaukee's first-round sweep of the Detroit Pistons. He's the favorite to win the NBA's MVP award.

How well the Celtics guard Antetokounmpo likely will determine the outcome of this second-round series, and Horford is off to a nice start so far.
