Tubert won the event, firing a final-round 70 for a 211 (69-72-70) to lead Arkansas to a 291. It was the lowest team round by 10 strokes.
The Razorbacks trailed host Oklahoma by five strokes heading into the final round, but rallied Sunday for the win.
Tubert began the day on the 10th hole and played even through 13 where she birdied with par five. She finished the back side one under. Tubert dropped another stroke after making the turn and counting a three on the par four first hole.
Tubert gave a stroke back on the fourth hole with a five, but again fell to two-under with a birdied on the final hole of her round.
"I couldn't be more proud of what we did this weekend," Arkansas Coach Shauna Estes-Taylor said on the Razorbacks' website. "Four of the five players birdied their last hole.
"Emily is not afraid to win, in fact she thrives under that kind of pressure. She is a special player and she's going to be fun to watch."
Arkansas won the event with an 871 (290-290-291).
Tubert was a two-time Pacific League champion at Burroughs. She also won the CIF Southern Section title in 2009.
