Georges Niang scored 22 points and Number 17 Iowa State beat George Mason 79-67 on Sunday in the first round of the Diamond Head Classic.
The Cyclones (9-0) had their second-lowest scoring game of the season but still managed to extend their winning streak. Iowa State was one of 10 undefeated teams in Division I at the start of Sunday.
Three minutes into the second half, Niang stole the ball from Marko Gujanicic and his layup gave Iowa State its first 10-point lead at 40-30. After that, George Mason (5-5) pulled no closer than five points with 6:18 left.
Iowa State made just three of 14 3-point attempts in the first half (21 percent) but the Cyclones used a 10-2 run to avoid their worst half in any game this season.
