Ruff, who’ll play Division I St. Bonaventure next season, scored a game-high 16 points for the Yellowjackets. Ruff also had her varsity high of 18 rebounds to go along with seven assists.
Maria DiMartin contributed 14 points, and Brittney Herrick had 10 points and 10 rebounds for OHS.
DiMartin scored eight points as OHS outscored the Blue Raiders, 15-3, in the third quarter to take a 36-29 lead into the fourth quarter.
“She played her best game in an OHS uniform,” Miller said of DiMartin. “They were doubling on Mariah, so we were trying to run our offense to Maria’s side and Mariah did a good job finding her.”
Horseheads (14-3) will play Owego in the STAC final at 6 p.m. Friday at Binghamton University’s Events Center.
“I feel good (about the way we’re playing heading into sectionals), but this loss hurts a lot because of the position we were in,” Miller said. “Horseheads is a very good team.
“We can take a ton of positives out of this game,” he continued. “The kids have to put this loss in perspective and not let it set us back mentally.”
Miller said the Yellowjackets (15-2) will have the No. 1 seed for the Section Four Class B tournament. OHS is in search of its seventh straight sectional title.
Depending on how many teams qualify for sectionals, Miller said OHS could open the tournament Tuesday or Wednesday, and possibly play a doubleheader with Oneonta’s boys team.
Harpursville 52, Delhi 37
Mike Staples and Alex Specht scored eight points apiece for host Delhi, which lost in the championship game of the Midstate Athletic Conference 5-8 tournament.
The Hornets outscored Delhi, 24-11, in the fourth quarter to pull away from a two-point game.
Jon Andrews scored eight of his 13 points and Devon Dean had seven of his game-high 18 points in the fourth quarter for Harpursville.
