They faced the nation's top-ranked team, the NCAA defending champion and the "home" team.
Four of their six dual matches came down to the last encounter.
And they trailed 3-1 in the final.
The Stanford women overcame all of it to win their 18th NCAA team title.
Taylor Davidson won the deciding match for the third time in this year's NCAA Championships, giving the Cardinal a 4-3 victory over 12th-seeded Oklahoma State today in Tulsa, Okla.
"My dreams just became reality," the 46th-ranked Davidson, a junior from Statesville, N.C., tweeted after vanquishing No. 44 Vladica Babic 3-6, 7-5, 7-5 on Court 2. "We are the 2016 NATIONAL CHAMPIONS!!!! Nothing compares to this feeling. Nothing. Number 15? No. Number 1."
About 700 fans made the one-hour drive from Stillwater, Okla., where Oklahoma State is located, to cheer on the Cowgirls (29-5).
With Oklahoma State leading 3-1, Stanford freshmen Caroline Lampl and Melissa Lord won on Court 5 and 6, respectively, after losing the first set.
