After playing a classic, seven-game, first round NBA Eastern Conference playoff series last season, the Boston Celtics and Milwaukee Bucks meet again this time around — but in the conference semifinals this time. In 2017-2018, the Celtics grabbed the second overall seed in the East, per Basketball Reference, while Milwaukee placed seventh, Yet in a series where the home court held throughout, the higher-seeded Celtics used that home advantage to pull out the victory. That being said, the roles are largely reversed this time, as the fourth-seeded Celtics must win at least one game on the top-seeded Bucks’ home court. All of this will kickoff in the first game that will live stream on Sunday.

To find out how to watch a live stream of the Boston Celtics vs. Milwaukee Bucks opening game of the NBA Eastern Conference semifinal series, use the streaming information at the bottom of this article. The fourth-seed vs. first-seed matchup gets underway at noon Central Daylight Time at the 17,500-seat Fiserv Forum in Milwaukee, Wisconsin, on Sunday, April 28.

That start time is 1 p.m. Eastern Daylight Time, 10 a.m. Pacific. In the United Kingdom, tipoff time for the Celtics-Bucks semifinals series opener will be 6 p.m. British Summer Time.

Milwaukee appears to have every advantage, according to an ESPN analysis. In addition to the home-court edge, the Bucks finished 11 games ahead of the Celtics in the regular season standings and boasted a point differential about twice the size of Boston’s.

The Bucks also have Giannis Antetokounmpo, the 24-year-old “Greek Freak” who appears likely to capture the NBA MVP award, per USA Today. Antetokounmpo is in his sixth season after being drafted by Milwaukee 15h overall in the 2013 NBA Draft.

If the Celtics have an edge, it would come in the form of playoff experience. While Boston has advanced all the way to the Eastern Conference Finals two years in a row — when the Bucks swept the Detroit Pistons in the first round — they scored their first playoff series win since 2001, per BR.
