UMBC fell to 6-7 overall, while Stony Brook won for the seventh time in nine games and improved to 8-5 overall.
It was Proctor's sixth double-double of the season and the fifth in his last seven games. He was coming off a personal UMBC-best 29 point effort on Tuesday at Saint Louis. He hit nine of 17 shots from the floor and all eight free throw attempts in 40 minutes of action. However, junior forward Justin Fry (New Bloomfield, Pa.) was the only other Retriever in double figures with 12 points.
But the Retriever quickly erased most of that deficit as they opened the half on an 11-2 run, capped by Fry's jumper just 2:59 into the frame. The previous possession, senior guard Jay Greene (Whitehall, Pa.) ended an 87-minute drought from behind the arc with UMBC's first and only trifecta of the game.
The critical stretch took place with the score tied at 54-all, as after a Seawolf timeout and the shot clock down to single digits, El-Amin hit a three-pointer off the ensuing inbounds play. After a UMBC miss, SBU picked up a loose ball and freshman center Danny Carter hit a tossed-up three-pointer at the end of the shot clock to give the visitors a 60-54 advantage with 2:55 remaining.
The Retrievers did convert 14 of 15 free throw attempts, outrebounded SBU, 36-30 and committed only six turnovers. But the visitors avenged a three-game series sweep from a year ago and cut the series deficit to 8-6 overall.
