LOS ANGELES (AP) — The Boston Celtics blew most of a 27-point lead in the fourth quarter before holding on for a 121-113 victory over the Los Angeles Lakers. Jaylen Brown scored 40 points in the Celtics' fifth straight victory. Brown made 13 of his first 14 shots and hit three 3-pointers while falling two points shy of his career high for the Celtics, who have won eight of 11 despite an embarrassing finish at Staples Center. Boston led 113-86 with seven minutes to play, shortly after coach Brad Stevens pulled his starters. But Talen Horton-Tucker and Ben McLemore led a 24-2 run.
