Jon Larranaga's layup with 12 seconds left gave George Mason a 71-70 win over Mississippi, snapping the nation's second-longest winning streak against non-conference competition at 44. Larranaga's game-winner capped a comeback by the Patriots, who trailed Ole Miss 70-63 with 2:12 remaining. George Mason, with two NCAA Tournament appearances in the past three years from the Colonial Athletic Association, improved to 4-1. Mississippi fell to 4-2. The Rebels had not lost to a non-conference opponent at home since a loss to Davidson in November of 1995. ``We were very aware of the homecourt dominance of Mississippi and we knew it would be difficult to do what we did,'' George Mason coach Jim Larranaga said. ``We view Ole Miss as a Top 20 team, especially in this place and to win here is a great accomplishment.'' Jon Larranaga, the coach's son, dribbled the length of the floor, beating the Mississippi press, to score the decisive layup. ``I thought they were going to throw fullcourt pressure at us and they did. That gave me room to drive to the basket,'' Larranaga said. ``There was no one near me. I took the shot and it went in.'' Rob Anderson scored 23 and Larranaga scored 22 to lead the Patriots. David Sanders led Ole Miss with 17. Aaron Harper had 14. ``It's disappointing, naturally, to see the streak come to an end,'' Mississippi coach Rod Barnes said. ``It's especially disappointing because we had the lead and opportunities to put distance between us.'' Ole Miss led for the majority of the game, including 33-32 at halftime. Two seasons ago, George Mason almost defeated Maryland, which owns the nation's longest homecourt winning streak against non-conference opposition at 80.
