It was still even, 44-44, when, with 1:23 to play, Romeo hit a free throw to nudge CBA in front, only to have Seymour answer with a jumper from the corner with 55 seconds left, setting up the final sequence.
Several times, CBA had shots to reclaim the lead and missed - but it chased down the misses in a prolonged possession until Voorheis was fouled. Calmly, Voorheis hit both of her foul shots, giving her 12 points for the night.
Liverpool called time-out with nine seconds left. After a foul with 2.1 seconds to play, the ball was inbounded in the right corner, in front of the Warriors' bench. Chalifoux, with just two points all night, was unguarded and flashed open for the possible winning shot - but it rolled off the rim, and CBA had survived.
Yet getting past the AA semifinal might take a greater effort, as on Tuesday at 5 p.m. at LeMoyne College the Brothers meet no. 1 seed and two-time defending champion Cicero-North Syracuse, led by Connecticut-bound star center Breanna Stewart.
The winner will play Fayetteville-Manilus or Utica Proctor in next Sunday's final at 5:30 at Utica Memorial Auditorium.
