The Magic broke an 11-game, head-to-head losing streak against their Eastern Conference rival.
Moore, a second-year player from Purdue, finished with 12 points. However, it was his first seven, which came after ATLANTA held a 57-49 lead in the third quarter, that changed the momentum of the game. Moore hit a floating jumper, a layup and a runner that became a three-point play, getting the Magic back in the game.
Guard Arron Afflalo led the Magic (5-9) with 26 points, breaking his two-game streak of sub-20-point efforts. Guard Victor Oladipo and forward Andrew Nicholson each scored 18, and center Nikola Vucevic tallied 12 points and a game-high 15 rebounds.
ATLANTA jumped out to a 7-0 lead in the first quarter, but Orlando quickly caught up and took an 11-10 lead. The rest of the entertaining period included five lead changes, with Orlando ahead 26-25 at the horn.
The Hawks used some accurate outside shooting to take a 51-43 lead. An 11-2 run was sparked by a pair of 17-foot jumpers from Horford and two driving baskets by guard Shelvin Mack. The Hawks had a 53-49 advantage at halftime.
NOTES: ATLANTA G Kyle Korver extended his streak of consecutive games with a 3-point basket to 88 when he knocked down a shot from the top of the circle with 4:05 left in the second quarter. Orlando G Jameer Nelson, who was not in the game at the time, had done a good job denying the ball to Korver. Korver could tie the NBA record of 89 straight held by Dana Barros on Wednesday against the Rockets in Houston, and he potentially could break the record Friday at home against the Dallas Mavericks. ... Orlando de-activated F Solomon Harris, who missed 12 games with a high ankle sprain. Harris experienced recurring pain after scoring six points in Sunday's game against the Phoenix Suns. He was replaced on the roster by F Kyle O'Quinn, who has a sprained right ankle and did not dress. O'Quinn is listed as day-to-day. ... Over their previous three games, the Hawks averaged more than 100 points and allowed only 89.3. ... Orlando hosts the Philadelphia 76ers on Wednesday.
