In other league action, Princeton (15-6, 5-4) is struggling to stay in the Ivy title race.
The Tigers split their weekend games, beating Brown 64-50, but losing to Yale 53-52 on Yale freshman Katy Grubb's jumper with 10.8 seconds remaining.
A loss to Harvard this weekend would all but eliminate Princeton.
Hapless Penn (0-21, 0-9) continued its lonely sojourn in the Ivy League cellar, in spite of the stellar play of senior Natasha Rezek, who recorded her 13th double-double of the season against Brown.
Penn once again came close, but the opposition emerged with the cigar. The Quakers lost to Yale 53-49 and Brown 46-40.
With several league games remaining, however, there may still be significant shuffling in the standings.
