WASHINGTON (Ticker) -- Gerry McNamara made the most of his chance to make up for a rare missed free throw late in regulation.
McNamara scored 10 of his 22 points in overtime and fellow freshman Carmelo Anthony had a season-high 30 and 15 rebounds as No. 15 Syracuse rallied for a 93-84 triumph over Big East rival Georgetown.
McNamara's jumper gave Syracuse the lead for good with 4:29 left. His second 3-pointer of the extra session put the Orangeman ahead, 88-80, with 2:26 to go.
Mike Sweetney converted four consecutive free throws to pull the Hoyas within, 88-84, with 1:58 left, before Craig Forth dunked for Syracuse. McNamara put in two from the line and Kueth Duany added another free throw for the final margin.
Syracuse took its first lead of the game, 62-60, on a steal and jumper by Anthony with 6:16 left in the second half.
Courtland Freeman gave Georgetown a 74-71 lead with a free throw with 67 seconds left in the half, but freshman Billy Edelin scored five straight points to give Syracuse a 76-74 advantage with 49 seconds remaining in regulation.
Anthony failed to convert two shots from the line that would have given the Orangemen a four-point advantage. McNamara missed the first of two free throws, but his second effort did push Syracuse's lead to 77-74 with 11 seconds left. He was 9-of-11 from the line after entering the game having made all 41 attempts from the stripe in conference play.
"I wanted to make up for missing the free throw late in the second half," McNamara said. "I got a couple of open looks in overtime and made the shots. I have a lot of confidence in myself and I've always been a big shot guy."
Syracuse coach Jim Boeheim agreed.
"Gerry is our guy for the big shots," he said. "Even though he's a freshman, I want the ball in his hands when we need a three."
Syracuse made 5-of-7 shots from the field in overtime, while Georgetown missed all four shots from the floor, getting all seven of its points from the free-throw line.
Gerald Riley drained a 3-pointer from the top of the key off a broken play with six seconds to go in regulation to knot the game at 77-77. Edelin attempted a half-court heave just before the buzzer but it hit the backboard.
Warrick finished with 14 points and a career-high 18 rebounds for Syracuse (21-4, 11-3 Big East West), which won its fifth straight game - the fourth in come-from-behind fashion.
The Orangemen, who lead the West division, need just two more wins to claim at least a share of the division title. They avoided a three-game losing streak at the MCI Center and swept the regular-season contests against the Hoyas.
Sweetney scored 27 of his 31 points after the first half, grabbed 19 rebounds, dished out seven assists and blocked seven shots.
"This loss hurt," Sweetney said. "We were in control for most of the game and let it slip away. We didn't do a very good job on the boards."
"We played good defense on Sweetney in the first half," Boeheim said. "He is the best low-post player in the country and we knew he'd get going."
But Georgetown (13-12, 5-9) fell to 1-7 in overtime over the past two years, including three losses this season.
"Unfortunately, we've had a lot of practice at this," Hoyas coach Craig Esherick said. "If I knew the answer, we'd stop doing it."
The Hoyas were outrebounded, 60-43, and outscored, 32-11, in second-chance points.
"The key to the game was that we couldn't rebound at all," Esherick said. "We were terrible on the boards. We had a good defensive effort, but effort doesn't count if you don't get possession of the ball."
"I'm shocked by the rebound statistics," Boeheim said. "We battled hard and we were able to come back from all the deficits."
Anthony, who hails from nearby Baltimore, was trying too hard in front of his hometown fans in the first half. He was just 3-of-10 from the field over the first 20 minutes before finishing 12-of-29. But the star forward converted just 5-of-13 free throws and 1-of-7 3-point attempts.
"He was trying too hard since he was playing at home," Boeheim said. "Once he settled down, he settled into a rhythm."
Georgetown scored the first 11 points of the game. The Hoyas opened the second half with a 15-6 run to take their largest lead, 45-33, on Riley's fast-break layup with 13:13 remaining in the second.
"We just took this game play-by-play," Anthony said. "We didn't panic when we were down 12. We showed heart and toughness to come back."
Edelin scored 14 points for Syracuse, which shot just 38 percent (30-of-78) and made just 28-of-41 (68 percent) from the line.
Tony Bethel tallied 19 for Georgetown before fouling out and Freeman had 11. The Hoyas missed a chance to clinch a spot in the Big East tournament.
