Syracuse (20-1, 7-1 Big East) has won seven straight since a home loss to Pittsburgh and has defeated Georgetown (15-4, 6-3) six consecutive times in the Carrier Dome.
It was the 819th career win for Orange coach Jim Boeheim, breaking a tie with UConn's Jim Calhoun for sixth in Division I. Boeheim also extended his Division I record for most 20-win seasons to 32 in his 34 years at his alma mater.
Austin Freeman led Georgetown with 23 points and Jason Clark had 15. Greg Monroe had eight points and only four rebounds before fouling out with 6:27 left. Chris Wright, averaging 15 points, finished with seven.
Syracuse, which trailed by 14 just 3 minutes into the game, started the second half with an 18-8 surge to take command as the Hoyas failed to find the openings in the Orange's zone defense that they did early.
After only attempting two shots in the first half, Rick Jackson converted a lay-in, a deft hook over Monroe along the baseline, and a follow after a steal by Johnson — all in a 79-second span — to give the Orange a 43-33 lead with 16:10 left.
