Le'Bryan Nash scored 21 points and Anthony Hickey and Phil Forte added 14 each to lead Oklahoma State to a 73-58 rout of in-state rival Tulsa in the championship game of the MGM Grand Main Event.

The Cowboys (6-0), who defeated Oregon State in Monday's opening game, shot 52 percent and coasted in the second half after leading by 15 points at the break.

Tulsa (3-2) lost its opportunity to get back in the game, missing its first five shots in the second half and falling behind 52-31 less than five minute into the period. The Golden Hurricane didn't get its first basket until just over 6 minutes in when Shaquille Harrison scored on a layup.

Harrison scored 17 points for Tulsa, which shot just 35 percent for the game and had two assists on 16 baskets. James Woodard added 13 points with 7 boards and Rashad Ray had 12.
