There has been a lot of sickness going through the Jonesport-Beals boys basketball team, but you wouldn’t have known it based on Monday night’s performance in its Class D North quarterfinal against No. 9 Greater Houlton Christian Academy at the Cross Insurance Center in Bangor.

Senior forward Ryan Alley poured in a game-high 21 points and the Royals’ smothering and relentless full-court press forced 26 turnovers as top seed Jonesport Beals remained undefeated with a 58-39 victory.

“Their press is really tough to play against. And they’re very athletic,” GCHA senior center Parker Brewer said.

“Every night, we get after it defensively. That’s the key to our success so far,” said Royals senior Ryan Alley.

“The kids work hard and they like to press,” said his father, Jonesport-Beals coach Skipper Alley, whose team outrebounded GCHA 37-22.
