The Boston Celtics were just 0.5 seconds away from taking would have been an all-but-unsurmountable 3-0 lead in their Eastern Conference semifinal series against the NBA champion Toronto Raptors. But the Raptors avoided midnight inside the Bubble at Walt Disney World’s ESPN Wide World of Sports in Lake Buena Vista, Florida with a 104-103 victory over the Celtics in Game 3 Thursday. Kyle Lowry channeled his inner Patrick Mahomes and lofted a perfect pass to OG Anunoby, who toasted an out-of-position Jaylen Brown for the game-winning three-pointer as time expired.

Series Reaches Potential Turning Point In Game 4

After the loss, the Celtics realized the opportunity they had squandered in allowing the Raptors to win Game 3. Brown, who has emerged as a team leader on and off the court carrying a maturity that belies his age, took responsibility for Boston’s failure to take a 3-0 series lead. "That was just a (expletive) disgrace at the end of the game," Brown said. "That was just terrible . . . There’s no way we should have lost that game. I take responsibility for that.” The Celtics got 19 points from Brown and 29 from Kemba Walker, who had his best game in the Bubble. While the Celtics presented a solid all-around effort with five players in double-figures in Game 3, the Raptors did them one better literally and figuratively with six players who scored at least 10 points.

Kyle Lowry led the Raptors with 31 points in Game 3, all of which came before his dime lofted over the out-stretched arms of 7-foot-5 Tacko Fall and past every Celtics player on the flood to set up the game-winning shot. Those fireworks struck Disney World after the Celtics had taken a two-point lead when Walker fed a wide-open Daniel Theis for a dunk with a half-second left.
