A freshman from Exton, Pennsylvania, O'Sullivan carded a 36-hole 143 to finish second in her collegiate debut at the Montevallo Full Moon Invite at the par-71, 5,895-yard Timberline Golf Club.
O'Sullivan opened the event with an even-par 71 before posting a one-over 72 in Tuesday's final round which tied for the low round of the day.
The Valkyries finished second as a team with a 602 (299-303), one spot better than fellow Conference Carolinas program Belmont Abbey.
