With a seed time of 8.07s, Young impressed in her preliminary heat, qualifying at 7.95s, good for second place.
She improved once again in the final, closing at 7.89s, besting the previous best mark in the history of the ODAC Indoor Championships, which was 7.90s.
Also topping that mark was Lynchburg senior Aleshia Washington, who won the event at 7.85s, forcing Young to settle for the silver medal, eight points and the best finish in Randolph program history in the meet.
Young continued to earn points for the WildCats later that afternoon, finishing fifth in the 200m in a time of 26.66s, besting her seed time of 26.91s.
First-year Marisa Quarti added more points for the WildCats in the 60m hurdles, finishing the event at 9.79s, good for fifth.
Mewhinney led the way in shot put, finishing three spots ahead of Jackson in 10th.
Hill and Reed made up the longer legs of the distance medley, joined by Sánchez and first-year Sophia Dill. The group finished eighth.
First-year Jasmine Cooper participated in the long jump.
Randolph's 12 points placed the team eighth on the day after not earning any points in either indoor or outdoor in the team's inaugural campaign last year.
"I couldn't be happier," head coach Bill Cooper said. "We came to the conference meet and improved based on how we did all year. I am excited going forward based on how we did today."
