"The guys played really well again," BYU men's golf coach Bruce Brockbank said. "Justin and Joe started great and got going with birdies. We're right in contention. We get to play with the top teams and hopefully we can play through the tough holes tomorrow. We're looking forward to it."
The Cougars finished 6-under-par for the day, 7-under for the tournament, to trail No. 4-ranked California by nine strokes entering Friday's final round. BYU is tied with No. 12 Texas A&M in second place, while No. 21 New Mexico is eight strokes off the Cougars pace in fourth overall at 1-over-par.
