Terry Henderson hit the go-ahead 3-pointer with 2:57 left in overtime to help North Carolina State beat Tennessee State 67-55 on Saturday.
Henderson finished with 21 points for the Wolfpack (7-2), while freshman Dennis Smith Jr. came up with a key three-point play with 58.5 seconds left and a punctuating windmill breakaway dunk to cap a game-closing 14-0 run.
BeeJay Anya also came up big with 12 points, 14 rebounds and seven blocks.
Wayne Martin had 16 points to lead the Tigers (7-2), who led by eight early in the second half before going scoreless for more than 8 minutes as N.C. State rallied.
Smith finished with 19 points, including a tough fading shot to tie it at 50 with 46.4 seconds left in regulation. He also blocked Tahjere McCall's drive to get the ball back, but Martin swatted Smith's driving shot for the win to force OT.
