Horford hit two tying free throws with five seconds to play to force overtime and then hit a fade-away jumper as time expired to lift the Hawks over the Wizards 101-99 on Friday night at Philips Arena.
Tied 99-99 with 1.01 second to play, Hawks forward Pero Antic lobbed an inbounds pass to Horford, who hit a five-foot baseline jumper for the winner.
The Hawks took a 10-point lead into the fourth quarter, but saw the Wizards cut the lead to 82-81 on a razzle-dazzle layup from Wall, who went behind his back for only third field goal of the night with three minutes to play. He later hit a pull-up jumper with time running down on the shot clock to give the Wizards their first lead of the second half.
It wasn't pretty for much of the game.
Wall hit just one of his first 10 shots and found himself on the bench after jacking up an air-ball 3-point attempt in the third quarter. Wall's potential winning jumper at the end of regulation also failed to hit the rim. Wall finished with 13 points on 6-of-22 shooting.
Both teams were coming off poor offensive performances and weren't crisp early. Air-balls, missed layups and lazy turnovers marred a sloppy first quarter.
The Hawks (12-11), who shot a season-low 35.6 percent in a Tuesday loss to the Oklahoma City Thunder, missed six of their seven shots. The Wizards (9-12), who scored a season-low 74 points in a Monday loss to the Denver Nuggets, opened Friday's game 5 of 17 from the floor.
The quality of play picked up in the second quarter. The Wizards got a spark from their bench, with guard Glen Rice Jr. connecting on a pair of 3-pointers, and center Jan Vesely adding a couple of baskets on the inside. The Hawks got going behind Horford, who hit 5 of 7 shots in the first half, helping the Hawks take a 48-46 lead into halftime.
