Another Friday night of highs and lows in local high school basketball.

The biggest high: The Nashua South girls won on the road vs. Portsmouth, ending a tough slump. “Huge win,” South coach John Bourgeois said. “The girls played out of their minds.”

The toughest low: The Bishop Guertin boys had an obscure call at the end of their game lead to an OT loss. But head coach Will Horne always stays positive. “The kids battled,” he said. “Great game.”

There were some others on this night — a career scoring night for a Saber, a steady win for the North girls. Read on:
