Hilary Knight scored a hat trick for the Badgers

PITTSBURGH - Junior Hilary Knight (Sun Valley, Idaho) posted her second hat trick of the season as No. 1 Wisconsin (11-1-0, 7-1-0 WCHA) earned the series sweep of Robert Morris (2-11-0, 1-2-0 CHA) with a 7-1 victory at the RMU Island Sports Center Saturday afternoon.

The Badgers netted two short-handed goals for the second-straight night, and five players had a multi-point game led by Knight's three-goal effort.

Juniors Brittany Haverstock (Hammonds Plains, Nova Scotia) and Brooke Ammerman (River Vale, N.J.) had career-best games as Haverstock tied her career game-high with three points on one goal and two assists and Ammerman tied her career game-high for assists with three.

Senior Meghan Duggan (Danvers, Mass.) added two goals, and junior Carolyne Prevost (Sarnia, Ontario) had one goal and one assist for UW.

Freshman goaltender Alex Rigsby (Delafield, Wis.) made 13 saves to improve to 7-0-0 on the season as the Badgers outshot the Colonials, 34-14. RMU goaltenders Daneca Butterfield and Kristen DiCiocco combined for 27 saves. Butterfield fell to 0-7-0 and made 21 saves in the first 35:42 of the game before DiCiocco entered the game in relief, making six saves and allowing the last two goals.

Haverstock netted her first goal of the season to give the Badgers a 1-0 lead at the 12:19 mark of the first period. Ammerman fired a pass from the right side of the slot to Haverstock streaking up the left side, and she buried it to put UW on the board.

The Badgers took a 5-1 lead after two periods, fueled by a four-goal second period. Duggan and Prevost scored back-to-back short-handed goals at 1:47 and 3:09, respectively, marking the second-straight game Wisconsin scored two goals while killing a penalty.

RMU's Kathryn Stack scored her first goal of the season at the 3:41 mark off an assist from Jennifer Kindret to cut the Badgers' lead to two, but Knight responded with two goals to finish off the second frame. She netted an unassisted goal at 8:29 before scoring off a feed from freshman Kelly Jaminski (Wisconsin Rapids, Wis.) with 4:18 to play in the period.

Wisconsin capitalized on two power-play goals in the third period as Duggan and Knight each scored with the man-advantage. The Badgers went 2-for-11 on the power play in the game, while Robert Morris was 0-for-1.

The Badgers return to WCHA action when they host Minnesota Duluth in a Friday/Sunday series next weekend. Puck drop is set for 2 p.m. at the Kohl Center both days.
