The Celtics outscored Atlanta 12-3 in overtime Sunday night at TD Garden to grab a thrilling 104-95 Game 4 victory. With the victory Boston tied the series, 2-2, with Game 5 slated for Tuesday in Atlanta (8:30 p.m., TNT, CSNNE).

The Celtics got a gift at the end of regulation when Hawks guard Jeff Teague was unable to get a shot off despite have Isaiah Thomas isolated at the top of the key. Teague wasted far too much time, was unable to make much of a move to the basket and the ball slipped out of his hands with three seconds remaining as he attempted to pull-up to shoot from well-beyond the 3-point line.

Amir Johnson scored the first five points of the extra session for the C's after being a relative non-factor offensively prior. Isaiah Thomas led the Celtics in scoring once again with 28 points while Marcus Smart pumped in 20 points off the bench.

The C's were able to grab the victory despite a dominant effort by Hawks forward Paul Millsap, who scored 45 points.
