Entering Saturday's doubleheader against ACC rival Virginia, the Tar Heels had lost nine of the 13 contests this season that were decided by two runs or less, many of those losses at the hands of top competition.
Against the Cavaliers at Finley Field, UNC alleviated the problem in the first game, prevailing 2-1 in nine innings in its ACC opener.
However, the Tar Heels failed to fully correct the problem in game two, playing to a scoreless tie through six complete innings when a downpour halted the action.
The contest was to be resumed at 8 a.m. Sunday, but the overnight rains forced it to be postponed.
The Tar Heels (22-13-1) showed grit in their ACC opener against the Cavaliers (30-9), showing what they learned from tough play at the KIA Classic in Fullerton, Calif. during spring break.
"Mentally, I think we were stronger," UNC coach Donna Papa said. "Our trip out West helped us with the level of competition. Even though we lost, we were even with some top teams for most of the games, and that has helped us prepare for our ACC games."
Ironically, a prime scoring chance for UNC was dampened even before Mother Nature arrived to spoil the party.
After Tar Heel Rosie Gustavson reached on an error, bunt singles by shortstop Michelle Semmes and Natalie Anter loaded the bases with no outs.
Virginia coach Cheryl Sprangel removed pitcher Erin Allinder and replaced her with Kristen Dennis, who struck out seven Tar Heels in game one.
