Amherst took the lead for good on a 3-pointer by Shannon Finucane in the early going, but neither team led by more than four points until midway through the opening half. Williams applied full-court pressure and didn’t let the Jeffs shoot from long range early on, but the visitors found their rhythm and hit five of their first eight attempts from beyond the arc.

Stedman knocked down a pair of triples and scored eight points during a 10-2 run that gave Amherst some breathing room at 27-17 with eight minutes to play in the half. Kim Fiorentino and Stedman hit threes on back-to-back possessions to cap off a 16-4 run, making it a 33-19 game with 5:47 on the clock.

Williams senior Jill Greenberg stopped the bleeding with a jumper, but Amherst accounted for the final 12 points of the half. Marcia Voigt and Bridget Crowley came off the bench to help the Jeffs pull away, with Voigt closing out the scoring on a jumper that beat the buzzer and brought the score to 45-21.

Amherst was incredibly efficient in all facets of the game in the opening 20 minutes, shooting 5-for-10 from behind the arc and 10-for-10 at the line. The Jeffs turned the ball over only three times and got 14 points off 11 Eph turnovers.

Robertson gave Amherst the first bucket of the second half, but the Ephs would score the next 10 points of the game. Lisa Jarlis had five of those 10, making it a 47-31 game in favor of the visitors. The Jeffs would quickly push their lead back to 20, however, as Stedman stole the ball and coasted in for an easy two points with 15:26 to play.

Lem Atanga McCormick scored six consecutive points to give Amherst a 60-34 advantage, and the Jeffs’ lead would fluctuate between 21 and 27 points for the final 13:27.

Stedman finished with five rebounds, three blocks and two steals to go along with her 22 points, while Robertson added 10 rebounds -- seven offensive -- for her third double-double of the season.

Voigt chipped in with 10 points, five rebounds, three assists and two steals in an efficient performance off the bench. Fiorentino finished with 11 points and seven rebounds, as the Jeffs held a 47-32 advantage on the glass.

Ellen Cook had 12 points and Grace Rehnquist added 10 for the Ephs, who shot 35 percent from the field and were 17-for-29 at the line.
