CHENANGO FORKS -- When Oneonta High's Grace Frabel pounded a spike from the middle for the match's final point, the Yellowjackets celebrated a hard-fought 12-25, 25-23, 13-25, 25-22, 16-14 victory over Chenango Forks in a Section 4 Class B volleyball quarterfinal Tuesday.

Fifth-seeded Oneonta (9-8) will join Tuesday's other winners -- second-seeded Susquehanna Valley (11-4) and No. 3 Lansing (15-1) -- in Thursday's Class B pool play competition at top-seeded Windsor (15-2). Competition begins at 4:30 p.m. with each team playing two games other three squads. The two teams with the best records will advance on Saturday's final at 6 p.m. at Corning.

SV defeated seventh-seeded Whitney Point, 3-0 and Lansing earned a 3-0 victory over No. 6 Waverly.

The Blue Devils (9-7) scored the first three points of the final game, all coming on blocks -- two by Maggie Warpus and one by Savannah Stinson. Forks received five kills from Jessica Stone in the final game, all coming from the left side.

Three of finishes gave Forks leads of 7-3, 9-6 and 12-10.

A dink by Oneonta's Hayden LeFever concluded a long point and pulled the Yellowjackets to 12-11. When Aubry Microni served an ace, Oneonta had a 13-12 lead, but another kill by Stone evened things at 13.

LeFever's block on Stone gave OHS a 14-13 lead, but Stone answered with a kill on the next point.

The Yellowjackets won the next two points to earn the victory.

"That's been our whole season," OHS coach Lee Ferrara said. "We've experienced deficits quite a bit, so they just know to play through it."

With Forks ahead, 2-1 in games, Oneonta bolted to a 19-14 lead in the fourth game. The Blue Devils closed to 24-22 on an ace by Warpus, but Izzy Giacomelli closed it out for Oneonta on a kill from the left side that clipped the net and fell over.

LeFever finished with 10 kills and Microni had 21 aces for the Yellowjackets, who received five aces from Lily Bridger and seven digs from Giacomelli.

"I think it's going to be really good volleyball," Ferrara said of Thursday's pool-play tournament. "Windsor is playing great ball, Sus Valley has been playing great ball and it's going to be competitive. That's what's fun about it. Really, any two teams could advance.

"I love (pool play). I've been in that battle so many times. Sometimes, it works for us, sometimes it doesn't. Volleyball is a tournament-style sport. You saw the ups and downs today. There will be ups and downs the whole night and the best teams are going come out on top."

Susquehanna Valley received nine kills from Aida MacNamee in its victory over Whitney Point. Olivia Kumpon contributed seven kills and two blocks, and Kale Lillie finished with six kills and seven digs. Also for SV, Emma Aton had 20 digs, and Miley Urso had 25 assists and five aces.
