"I've got to give a lot of credit to the lefty. He was very impressive," said Helm.
Jimmy Sabbag led Guilderland's 16-hit attack with a triple and a double. Sabbag also drove in three runs, while Jake Colavito knocked two runs in with a pair of doubles. Ben Henderson added two singles and two RBI.
Nick Nardacci had a double and a single for Bethlehem, which advanced to the quarterfinals with a 15-6 nine-inning victory over Amsterdam last Thursday.
"I can't really complain," said Helm. "We got our seven (league) wins, we made the playoffs and we won a playoff game. We had a good season.""
