Tatiana Mathelier scored two goals in the first 11 minutes of the second half as the New Jersey Lady Stallions overcame the Long Island Lady Riders, 4-2, as the W-League playoffs opened Wednesday night at DePaul Catholic High School in Wayne, N.J.

Mathelier, a junior at Binghamton University, scored in the 47th and 56th minutes and the Lady Stallions (12-3-0) advanced to the Eastern Conference final this weekend against defending champion Boston Renegades (13-0-1) or the Ottawa Fury (11-2-1). Boston and Ottawa meet Thursday night in Framingham, Mass.

Princeton junior Esmeralda Negron scored in the 16th minute and assisted Mathelier's first goal. William Patterson University hall-of-famer Kathleen Sinram, a Lady Stallions assistant coach, also tallied for the New Jersey.

Long Island (9-6-0) outshot the Lady Stallions, 18-9, but former Green Mountain College goalkeeper Sarah Allen made 13 saves for New Jersey.

Columbia University career goalscoring record-holder Tosh Forde and Duquesne University senior Lauren Bracco scored first-half goals for the Lady Riders.

Charlotte plays host to Northern Virginia and Northern Kentucky visits Chicago in Central Conference divisional finals on Thursday.
