Senior Katie Rigler led the Tigers with a first-half hat trick against Brown, while classmate Molly McBee helped keep Brown from getting close with a pair of second-half goals. It was a well-balanced offensive performance, as Princeton got its 11 goals from eight different scorers.
Another momentum-blocker for Brown was sophomore goaltender Ashleigh Johnson, who made 12 of Princeton's 13 saves before being replaced late for junior Cece Coffey.
In the nightcap, Princeton got a pair of goals in each quarter and shut the Crimson out in both the first and third quarters en route to an 8-4 victory.
Both Murphy and Jessie Holechek scored two goals apiece for Princeton, which is now 25-1 on the season. Hatcher, McBee, Rigler and Temple each added a goal for the Tigers, who will host George Washington Sunday at 1 pm in the home finale.
Johnson had 15 saves for Princeton, while Hatcher added two assists and two steals.
