Trailing by as much as six in the fourth quarter, Grimes stayed within sight, but Pulaski appeared to have weathered the challenge and led, 42-37, when everything came to a halt.
With 1:30 left, chasing a loose ball opposite the Cobras' bench, Hax hit her head on the floor and felt pain in her neck. Taking no chances, officials called for an ambulance and tended to Hax until she was taken to the hospital in a stretcher, leaving to a standing ovation from fans of both teams.
When the game resumed 20 minutes later, Heiselman hit a 3-pointer to cut it to 42-40. After an exchange of points over a tense final minute, Pulaski's Leah Ford was fouled with 5.1 seconds left.
With a chance to ice the game with two free throws, Ford only made one of them. A 3-pointer could force overtime, but the desperation Grimes shot was off target, ending the drama.
Hax, before the injury, had 18 points, a number Marcely matched. Heiselman had 10 points, while Cady Kalemba earned eight points. Ford helped Hax and finished with 13 points.
As the Blue Devils moved on to face undefeated Cooperstown in the C-1 semifinals, Grimes finished a 16-5 campaign, knowing it should be strong again next year as only Headd and Jill Tucci depart.
Everyone else, from Heiselman, Marcely and Kalemba to Brooke Bonacci, Emma Kelley and Tenley Pitonzo, should be back in 2008-09 to make another championship run -- and this time, it wouldn't surprise anyone.
