GROTON -- Groton-Dunstable senior ace right-hander Alyssa Ash (2-for-3, RBI, home run) no-hit rival North Middlesex, 8-0, Friday afternoon in Groton. Ash walloped a two-run home run over the wall in right center field to spark a five-run first inning for the hosts.

The Groton-Dunstable starter hurled a perfect game through five, but a throwing error and a catcher's interference call put an end to that.

Ash compiled eight strikeouts and issued no walks, all while battling through flu-like symptoms.

"She had no walks -- that's the most important thing to me because when she gets herself into trouble is when she walks batters," Groton-Dunstable head coach Derek Asadoorian said. "I don't think she has ever done that in her career. She tends to give up a lot of walks, but for her to be in this type of form in the last few games that she has pitched, she is really starting to come into her own in her senior year.

I hope that she can continue to keep it going because when she is on, we can compete with anybody."

Groton-Dunstable started the season on a five-game skid, but it has since rebounded with a four-game winning streak. North Middlesex is still trying to hit its stride at the plate, but it's defense has been dependable early in the season.

"Our offense could not get going today," North Middlesex head coach Becky Jackson said. "Against a pitcher like that, you have to jump on her early. She pitched a great game.


Emily Raposa recorded six put-outs for us in left field today -- she had a tremendous game. Coming out of that first-inning down five was really tough. If it wasn't for that, it would have probably been a 3-0 ballgame."

North Middlesex starter Hannah Lawrence surrendered a slap-single to Bucknell-bound senior catcher Celina Antonellis (2-for-2, run scored) to start the game. Antonellis swiped second before coming around to score on a RBI single to left by senior right fielder Erin Olson. Ash stepped into the box and pummeled a towering shot off the pine trees beyond the right center field fence to make it 3-0.

A pair of runs scored late in the inning on errors to put the Crusaders out in front, 5-0.

Groton-Dunstable tacked on two insurance runs in the third on a sacrifice-fly to deep left by Arianna Cho, which plated sophomore Emily Figueroa from third.

Bridget O'Malley came across on a throwing error to make it 7-0 after three. Groton-Dunstable added its final run in the fifth on a wild pitch.

North Middlesex's first base-runner of the game came in the sixth on a dribbler back to the circle by senior Marissa Amichetti that Ash airmailed over the head of Caroline Thompson at first.
