Hunter Grace contributed 10 points and Ben Standhart had seven points for the Wildcats.
“Give Gilboa all the credit,” O’Connell said. “They came ready to play and they played hard for 32 minutes. We did not shoot well tonight, but credit their defense.”
The Indians (11-7) were lead by junior Greg Mattice’s 12 points.
Matt Anderson contributed 10 points for Stamford.
Gilboa will host 14th seed Edmeston on Saturday in a quarterfinal.
H-T 50, Laurens 38
Dylan Legg scored a team high 17 points and teammate Zach Mudge contributed 16 points as fifth-seeded Hunter Tannersville advanced at home.
“Laurens came to play,” H-T coach Chris Glennon said. “Coach Carr does a nice job with them and they took it to us in the first quarter. Our defensive pressure got to them a little in the second half and Legg and Mudge were able to get some easy looks.”
Mudge’s night also included eight rebounds and five steals.
Laurens (9-9) was lead by Ryan Holmes, who had a game-high 22 points.
“The Holmes kid really had a good game for them,” Glennon said of Holmes, who hit four three-pointers. “We did not have an answer for him in the first quarter.”
The Wildcats (14-4) will travel to fourth-seeded Milford (14-4) on Saturday.
“We saw them in the Tri-Valley Championship game,” Glennon said. “They are a nice team and the Griffiths kid is a nice player, so we will have our hands full on Saturday.”
Milford 66, CV-S 50
Sophomore Peyton Griffiths scored a game-high 26 points, including three three-pointers, to lead fourth-seeded Milford to a home victory over Cherry Valley-Springfield.
Will Ward contributed 20 points and five assists for the Wildcats (14-4).
“This was by far Ward’s best offensive game of the year and it could not come at a better time of the season,” Milford coach Frank Spurchise said.
