It wasn't quite the rousing blowout from less than a week ago, but the Boston Celtics were more than happy with the outcome in Friday night's rematch with the Knicks. A driving lay-up with less than 10 seconds to play by Jeff Green capped off a furious fourth quarter rally for the Celtics in beating the Knicks 90-86. Unlike their matchup earlier this season, this game wasn't decided until the game's final seconds. After leading most of the first half, Boston found itself fighting off a strong surge by the Knicks which put them ahead 73-68, going into the fourth. New York went ahead by as many as nine points before a 3-pointer by Avery Bradley capped off a 16-5 run that gave Boston an 86-84 lead with 2:38 to play. When the two met on Dec. 8, Boston raced out to an 18-1 lead. On Friday, the first quarter featured three lead changes and nine ties before a buzzer-beating 3-pointer by Courtney Lee lifted Boston to a 29-26 lead after the first. Boston began to pull away in the second, fueled by a 19-5 run to start the quarter. Just when it seemed destined for a second pummeling in as many matchups, New York finished the second quarter with a 15-5 run that brought the Knicks within 54-48 at the half.
