The Dutchwomen (8-5-4, 3-2-2 Liberty League), who will be making their first conference tournament appearance since 2012, take on No. 1 William Smith in the Liberty League semifinals on Tuesday in Geneva, N.Y.  The Brewers (9-7-1, 6-2 Liberty League) will be the second seed in the tournament and will host Rensselaer.

Vassar pulled out to a 1-0 lead 13:08 into the first half on Audrey Pillsbury's seventh goal of the season.

Monahan provided the response for the Dutchwomen 25:05 into the stanza with her team-leading eighth tally of the season and her thid in the last two games on an assist from Keane.

Rebecca Andrews restored the Brewers advantage early in the second stanza, converting on a penalty kick at 56:05, but Staples netted the equalizer just 1:53 later on a pass from Keane.
