SALSIBURY, Md. -- Freshman pitcher Gabrielle Castelli allowed just one hit as No. 24 William Paterson (31-9) earned a 2-0 victory against Manhattanville (27-9) in the first game of the double-elimination championship.

Junior center fielder Kelsey Principe got the Pioneers' offense started during the bottom of the fourth, leading off the inning with a double to right-center field. After advancing to third on a sacrifice bunt from senior shortstop Katelyn Miele, she scored on a Kelsey Wimmershoff sacrifice fly to give WP a 1-0 lead.

The Pioneers made it 2-0 in the fifth. Freshman third baseman Rachel Wasilak reached on an error and advanced to second when freshman catcher Kim Fryer was hit by a pitch. After Castelli laid down a sacrifice bunt with two strikes to advance the runners, Wasilak scored on a strikeout and a wild pitch.

Manhattanville brought the tying run to the plate with two outs in the top of the seventh, but Castelli was able to get a strikeout looking to end the game.
