"We had to go smaller and quicker," said Holmes. "We had to put (defensive) pressure on, and it paid off for us with some layups and foul shots."
"They pressured us pretty good, which surprised us. We hadn't seen that all year long," said Osinski. "And it seemed like every time we turned the ball over, they made us pay."
Holmes re-inserted Sullivan, and he came through with a short turnaround jump shot in the lane. A short time later, Lanier converted a steal into a layup that pulled Shaker within four points at 54-50 with 1:12 left in the fourth quarter.
Unfortunately for the Blue Bison, there was nothing they could do to stop Marfurt at the free throw line. The Suburban Council's Player of the Year made five of his six foul shots down the stretch to prevent Shaker from getting much closer.
"With the game on the line, I definitely want the ball in my hands," said Marfurt, who finished with a game-high 24 points. "I'm a senior, and I want to have a say at the end."
Kost added a clutch layup and two free throws in the final minute to finish with 18 points for Guilderland, which advances to Thursday's semifinal against Christian Brothers Academy at the Times Union Center.
Sullivan had 20 points, Lanier contributed 12 points and Bonomo added 11 points for Shaker.
"It's been a good year for us," said Holmes. "It started out slowly for us, but we finished with a .500 record in the league and we had a road playoff win (a first round victory at Schenectady), which has never happened since I've been coaching here.""
