Arizona training camp notes, practice 13: Freshman receivers Gio Richardson, Isaiah Mizell shine

It was Friday, the 13th at Davis Sports Center and Dick Tomey Practice Fields for the Arizona Wildcats' latest training camp practice, even though it was on Aug. 15.

Here are notes and takeaways from Arizona's cloudy and overcast 13th training camp practice on Friday, as the Wildcats hit the two-week mark from their season-opening bout with Hawaii:

* After Arizona's defense recorded five interceptions between 7-on-7 and team periods on Wednesday, the offense had a productive day on Friday, especially its freshman wide receivers in Gio Richardson and Isaiah Mizell. Richardson hauled in a 26-yard over-the-shoulder touchdown from quarterback Braedyn Locke near the front-right pylon.

* Richardson and Mizell also had multiple first-down catches in a 7-on-7 period. On a slant route, Mizell caught a pass from Locke and bursted for a long touchdown. Richardson is trending towards becoming a mainstay in Arizona's receiver rotation. Mizell has Power 4 speed, but his 164-pound frame could benefit from a redshirt season and a full year in Arizona's strength program.

* Washington State transfer receiver Kris Hutson picked up back-to-back first downs in a 7-on-7 period.

* Defensive end Tre Smith tackled running back back Ismail Mahdi in the backfield. Smith went up against Michigan transfer right tackle Tristan Bounds for the TFL.

* Sophomore kicker Michael Salgado-Medina made a 48-yard field goal. Walk-on freshman Tyler Prasuhn missed his 48-yard attempt. Neither Salgado-Medina or Prasuhn have created separation in Arizona's kicking competition.

* Nickel back Treydan Stukes took his first reps in a team period on Friday. Stukes started alongside cornerbacks Michael Dansby and Jay'Vion Cole, free safety Genesis Smith and strong safety Dalton Johnson. Stukes had previously only taken reps in individual and 7-on-7 periods. Stukes kept up with wide receiver Javin "Nunu" Whatley in coverage on a deep pass.
