The Belles scheduled double-header against Manchester at home Thursday was postponed due to poor field conditions.
This was the second time the game has been postponed. It was originally to be played on March 11, but was moved to Thursday. So far, no make-up date has been set.
The Belles (8-2) will now begin their home season with a double-header against Rockford on Saturday.
Junior Calli Davison will start the first game Saturday for the Belles. Davison (5-2) has given up three earned runs in five starts this season - all wins.
"[Calli's] confidence shows on the mound," head coach Erin Sullivan said. "Our team has stepped up their defense behind her."
Senior McKenna Corrigan (3-0) will start the second game of the double-header.
Sophomores Ashley Peterson and Maureen Healy, junior Ashley Fusaro, Davison and Corrigan will lead the offense, which has overpowered nearly every team the Belles played in Florida during spring break.
Rockford also played at Ft. Myers, Fla., over spring break. However, Saint Mary's and Rockford did not meet.
