Banner No. 17 is up in the rafters, and win No. 1 is in the books. NBA finals MVP Paul Pierce scored 27 points and the defending champion Boston Celtics followed an emotional ring ceremony and banner-raising with a 90-85 victory over the Cleveland Cavaliers on Tuesday night. LeBron James scored 22, but he missed a driving layup with 41 seconds left and two free throws in the last 11 seconds.
