LeBron James had 43 points, 12 rebounds and 11 assists for his fourth triple-double of the season, and Cleveland overcame Paul Pierce's 50-point performance to beat host Boston.

Pierce shot 17 of 36 from the field and 16 of 20 from the free-throw line to become the first Celtic to score 50 since Larry Bird had 60 on March 12, 1985.
