Watch Kemba Walker Hit Half-Court Shot At Buzzer For Celtics Vs. Heat

It was a frustrating third quarter Tuesday for the Boston Celtics, who trailed the Miami Heat all game.

And as they got back into it with an 11-0 run in the third, that momentum got ruined with a plethora of foul calls.

A questionable charge on Gordon Hayward. Marcus Smart fouling out with three minutes to play in the frame. Jayson Tatum coming close to the same fate after putting up 11 third-quarter points.

The Celtics needed a shift, and Kemba Walker tried to give it to them.

As the final seconds ticked off the clock, Walker took an inbound pass, made a few dribbles and threw a shot up from half court to beat the buzzer.

The points helped Boston cut its deficit down to 91-83. Check it out below:
