BOSTON (AP) — Luka Doncic returned from a hamstring scare to hit a tying 3-pointer with a 1:21 left, Spencer Dinwiddie made the winner with nine seconds to play and the Dallas Mavericks spoiled Kevin Garnett’s special day by beating the Boston Celtics 95-92 on Sunday. With Garnett courtside awaiting the postgame ceremony to retire his uniform No. 5, the Mavericks won for the seventh time in eight games and snapped Boston’s five-game winning streak. Doncic, who left in the first half rubbing his left leg, finished with 26 points and eight rebounds. Boston’s Jayson Tatum missed an off-balance 3-pointer at the buzzer. Tatum had 21 points and 11 rebounds.
