With the help of a staunch defense, Rensselaer junior goalkeeper Steph Vargas posted two shutouts last week in a pair of Liberty League home games. She had four saves in 180 minutes on the weekend. Vargas stopped two shots, one in each half, of a 2-0 win over seventh-ranked William Smith on Friday and then made two first-half saves in a 3-0 shutout over RIT in a game between the two teams atop the league standings.
