Jayson Tatum, Boston Bash Knicks in Game 3

The Boston Celtics finally spilled the three and now they have a series with the New York Knicks.

New York's long-awaited return home became a metropolitan nightmare on Saturday afternoon, as the Celtics earned a 115-93 victory in Game 3 of the two sides' Eastern Conference semifinal set at Madison Square Garden.

Payton Pritchard scored 23 points in relief to lead the green men while Jayson Tatum had 22. Jalen Brunson led all scorers with 27 in defeat while Karl-Anthony Towns had a 21-point, 15-rebound double-double.

The Knicks now lead the best-of-seven set 2-1 but Boston no doubt built some momentum thanks to the rediscovery of their deep ball. Their historic outside shooting rates made all the wrong headlines after the first two games in Boston (25-of-100) but they shot an even 50 percent (20-of-40), which proved to be the perfect antidote for a Manhattan crowd taking in the most monumental Knicks game in quite some time.

Six different Bostonians hit at least two triples (with Pritchard and Tatum getting five each) while the Knicks as whole sank only five, three alone coming from the arms of Brunson.

Despite basking in the aura of MSG in springtime, the Knicks have lost three of the four games staged between Seventh and Eighth Avenue this postseason. Road teams remain undefeated in both Eastern semifinal sets, as the Cleveland Cavaliers kept that trolling in Friday's win in Indianapolis.

The Knicks will look to get back on the right track when Game 4 is staged at MSG on Monday night (7 p.m. ET, ESPN).
