Baylor guard Odyssey Sim (0) celebrates after the victory over Texas A&M in an NCAA college basketball championship game at the women's Big 12 Conference tournament, Saturday, March 10, 2012 in Kansas City, Mo. Baylor won the game 73-50.

WACO, Texas — Before 6-foot-8 junior phenom Brittney Griner gets the ball for undefeated Baylor, Odyssey Sims often gets everything started.

Sims usually works the ball up the court and makes a pass. But if opposing teams are intent on surrounding Griner with multiple defenders, the feisty point guard can just as easily make a jumper or drive to the basket herself.

As a freshman last season, Sims helped Baylor get to an NCAA regional final before a loss to eventual national champ Texas A&M.

The Lady Bears (34-0) haven't lost since and are the No. 1 overall seed in the NCAA women's tournament. They play Sunday against UC-Santa Barbara (17-15) in Bowling Green, Ohio.

Sims is averaging 14.8 points and 4.6 assists a game, both numbers better than last year.
