The Toronto Raptors want DeMar DeRozan to assume the role of fourth-quarter finisher. He played the part Friday night, shutting the door on one of the hottest teams in the NBA. DeRozan scored 13 of his 22 points in the third quarter and made four pivotal free throws down the stretch as the short-handed Toronto Raptors held off the Boston Celtics 84-79 Friday night.
