HP kept going inside, and with Bunal working her total to 17 points and Alyssa Curtis adding 15 points, the Golden Knights had a chance to snatch it away at the end if Grimes missed free throws.
But the Cobras didn't miss, Vaught sinking five of seven at the line in the last two minutes as she worked her total to 15 points and helped send Grimes to the next round.
Alex Guhin put in nine points and Megan Driscoll added seven points. Each of the nine Grimes players that saw action scored at least one field goal.
And this leads the Cobras to Onondaga Community College's SRC Arena (where it beat Bishop Ludden on Jan. 26) for Saturday night's Class B semifinal against Utica-Notre Dame, Grimes facing the major task of trying to contain one of the state's best players, Emily Durr, who scored 23 points in her team's quarterfinal win at Westhill.
The prize for Grimes or UND is, of course, a ticket to the Carrier Dome for next Thursday's Class B championship game against South Jefferson or Cazenovia, who play in the other semifinal Saturday right after the Cobras and Jugglers are done.
