Watch: Celtics' Bradley nails dagger 3 to snap Cavs' playoff winning streak

With Isaiah Thomas out for the playoffs with a right hip injury, Avery Bradley took over the title as Mr. Fourth Quarter for the Boston Celtics on Sunday night.

Bradley helped snap the Cleveland Cavaliers' 13-game postseason winning streak in the Game 3 thriller at Quicken Loans Arena, nailing a dagger 3-pointer with 0.1 seconds remaining to give Boston the 111-108 victory.

The 26-year-old finished the contest with 20 points on 8-of-23 shooting, four assists, three rebounds, and two steals in 42 minutes.

After surrendering 66 points over the opening two quarters, the Celtics tightened things up in the second half, holding the red-hot Cavaliers offense to just 42 points over the final two quarters.

Sunday's defeat marked the largest blown lead of LeBron James' playoff career, with Cleveland squandering a 21-point lead to the scrappy Celtics. It was also the largest upset in the last 20 postseasons, with the Cavaliers entering the game as 16.5 point favorites.

Game 4 tips off Tuesday, when the Celtics will attempt to defy all odds, and even the series at two games apiece.
