Hamline's softball doubleheader with St. Olaf has been postponed until Friday, April 20. Overnight rains plus the forecast of showers in the afternoon are the culprit. The teams will play at Meredith Field at 3:30 p.m. on April 20. It will be the start of a busy 26 hours for the Pipers. They will be back at Meredith Field on April 21 to host Augsburg in a 1:00 p.m. twinbill.
