The Starzz extended their advantage to 66-58 on a jumper by Jennifer Azzi with 4:58 to play, but the Comets stormed back behind WNBA Most Valuable Player Sheryl Swoopes, whose 3-pointer got Houston within 73-72 with 15 seconds left.

After Ferdinand made a pair of free throws with 12 seconds to go, Houston called timeout to set up a final play. Swoopes passed to Kelley Gibson, whose 3-pointer from the left wing with three seconds left was blocked by Azzi.

Swoopes snagged the loose ball and missed a desperation 3-pointer from NBA range just before the buzzer.

The game was overshadowed by a scary incident.

Play was stopped for 25 minutes when referee Bill Stokes collapsed near the scorer's table during a timeout with 15:33 left in the game. Stokes was treated immediately by medical officials from both teams.

He was taken to Southwest Memorial Hospital, where he is listed in critical but stable condition. The players were sent to their respective locker rooms while Stokes was being treated. The teams returned and had a brief shootaround before play resumed.

Utah shot 50 percent (28-of-56) for the game and limited Houston to 39 percent (27-of-69). Ferdinand added 18 points and Margo Dydek had 14 and nine rebounds for the Starzz, who won a playoff series for the first time in team history.

Swoopes had 28 points, but fellow All-Star Tina Thompson had just 12 on 5-of-16 shooting for Houston, which was a league-best 14-2 at home during the season and posted an 83-77 double-overtime win here in Game 2.
