First year Natalie Holm and Kristina Stoermer had 10 points each for St. Olaf (0-4, 0-1 MIAC) in the loss.
The game was marred by turnovers. Hamline had 26 and St. Olaf 23.
The Oles led by as many as five in the first half, but the Pipers had a 36-33 advantage at the break after Megan Haugen hit a 30-footer at the buzzer.
Hamline raced to a nine-point lead in the opening minutes of the second half. The Oles cut the lead to 54-52 on a jumper from Holm with 6:47 to play, but made just one field goal the rest of the way.
