Six Celtics scored in double figures, led by Jaylen Brown with 27 points, as Boston dominated the Toronto Raptors 111-89 Monday night to take a 3-2 lead in their best-of-seven Eastern Conference semifinal series near Orlando.

Kemba Walker added 21 points, Jayson Tatum had 18 with 10 rebounds, Brad Wanamaker and Daniel Theis scored 15 apiece and Marcus Smart 12 for the Celtics, who rebounded from two consecutive losses after they had blown a 2-0 lead in the series.

Boston will get the chance to clinch a conference-finals berth with a Game 6 victory Wednesday.
