Mohonasen had a chance to tie the game midway through the second half. Crounse broke into the penalty box on the left side and had an open shot on Schalmont goaltender Mike Falcone, but Crounse's shot hit the outside of the goal.
Flores sealed Schalmont's win seven minutes later. He headed the ball into the goal after a scramble in front to put the Sabres ahead 3-1.
Falcone stopped seven shots to help Schalmont stay unbeaten. Mohonasen goaltender Matt DiBiase had 10 saves.
Though Schalmont won this round of the Rotterdam rivalry, Bailey said Gregg's Mohonasen team will be tougher when they meet again next year.
"We're going to graduate a lot of seniors," Bailey said. "They only have five seniors, so they're going to have a lot of players back."
Both teams now shift their focus to their respective leagues. Schalmont currently sits atop the Colonial Council with six points, one point ahead of defending league champion Voorheesville, while Mohonasen is still looking for its first league win after drop-ping its first two Suburban Council games.
"We're better in many aspects, but we still need a lot of work in areas such as ball skills and first touches," said Gregg. "We're not physically there yet, but they're giving me everything they've got, and that's all I can ask for as a coach."
Mohonasen hosted Ballston Spa Tuesday night, while Schalmont visited Cobleskill-Richmondville.""
