Hartman's final game at Oklahoma was the 143rd of her career, an Oklahoma school record.
OU's previous games-played record was held by guard Danielle Robinson, who appeared in 141 games from 2007-10.
Hartman played 36 minutes Sunday, working mostly in place of starting point guard Morgan Hook, who left with concussion-like symptoms early in the loss.
Hartman finished the game with two points and eight rebounds.
