Perez finished the game 3-for-4 with three RBIs and Robinson went 2-for-4 with an RBI.

Freshman Devin Wright continued to throw well in the javelin as he took home his second-straight silver prize with a mark of 56.93 meters (186-09).
"Today was one of those days where we are looking for improvement and really, at this time of year that is what we are looking for," said Utah State veteran head coach Gregg Gensel. "What we saw today was everyone being consistent or improving and that is what we want."
Other top-five finishers for the USU women included seniors Sonia Grabowska who vaulted 3.86 meters (12-08.00) in the pole vault to place third.

Freshmen McKenzie Johnson and Shaleen Richardson joined Whitworth and Haymore to cross the finish line in the 4x100-meter relay with a time of 48.69, which was good enough for fourth-place.
Other top-five finishers for the Utah State men included seniors Daniel Howell and Aaron Clements who finished fourth and fifth in the 1,500 meters with times of 3:54.51 and 3:54.87, respectively.
