Watch: Al Horford extends Hawks' lead with 3rd-quarter buzzer-beater

It was a shot to beat the buzzer, and perhaps one last shot to the gut of the Boston Celtics in a win-or-go-home Game 6.

With the clock winding down in the third quarter, Atlanta Hawks All-Star Al Horford worked over the diminutive Marcus Smart by drilling a fadeaway jumper in his eye, putting his team up by 21 with just 12 minutes to go.
