NEW YORK (AP) Isaiah Thomas scored 27 points, Marcus Smart made a tiebreaking 3-pointer with 47 seconds left after Boston blew a late lead, and the Celtics beat the New York Knicks 119-114 on Sunday.
The Knicks wiped out a late nine-point deficit with an out-of-nowhere 11-2 run in a little more than a minute, but Smart answered with his shot and Avery Bradley and Al Horford made big defensive plays afterward.
Jae Crowder and Kelly Olynyk each had 16 points for the Celtics, who won for the fifth time in six games.
