Boston and Philadelphia, who have met more than any other NBA teams, kick off their series Monday.

Boston won three of four meetings in the regular season, but the margin was single digits in every game.

Boston scores the final 11 points to earn a 128-120 victory in Game 6, setting up a second-round matchup against the 76ers.

Trae Young hit a 3-pointer with 2.8 seconds left as Atlanta wins, 119-117 to pull within 3-2 in their first-round series.

Joe Mazzulla played Robert Williams III and Al Horford together down the stretch and the move paid big dividends.

Jaylen Brown and Jayson Tatum lead Boston with 31 points apiece, and the Celtics will have a chance to wrap up the Eastern Conference quarterfinal series at home on Tuesday.

Boston struggled defensively and allowed Atlanta’s bench to get hot in a 130-122 loss.

Trae Young scores 32 points and Atlanta cuts Boston’s lead in their first-round series to 2-1.
