The four-star, dual-threat quarterback from Clovis West High in Fresno, California is currently verbally committed to Tennessee, but said he thoroughly enjoyed his official visit to Nebraska this weekend.
"It went great," he told the Journal Star on Sunday. "I wasn’t really sure what to expect coming in but it was an awesome visit."
Martinez said his visit host was another young quarterback from California, freshman Tristan Gebbia.
"I spent the most time with (freshman wide receiver) Tyjon Lindsey and (Gebbia) and other freshman players," he said. "(Quarterbacks coach Mario Verduzco) and Frost spent a lot of time with my dad and I as well.
