LOWELL -- Sophomore Alyssa Zinkiewicz's sacrifice fly in the fourth was all UMass Lowell ace Marielle Handley needed, shutting out Dartmouth in a 1-0 softball victory at River View Field on Tuesday.

A 20-game winner a year ago, Handley picked up her fifth win of the season and etched her name in the record books as the first River Hawk to win a shutout as a Division I program.

Handley gave up four hits while striking out three in a complete game performance that ended the River Hawks six-game slide.

"I hit my spots, definitely used the changeup which was effective, challenged them, limited my walks and went right at the batters," said Handley.

UMass Lowell improves to 9-29 overall and remains 1-10 in the America East, while the Big Green drop their second straight and fall to 26-15 overall and 15-1 in the Ivy League.

The River Hawks' winning run came in the fourth inning when Ally Greene (Tewksbury) reached on an error to lead off the inning. Greene stole second and advanced to third on a single by Emily O'Brien before coming in on Zinkiewicz's sacrifice fly.
