He may be the No. 1 overall pick in the 2018 NBA Draft -- the first such pick in Suns history -- but after Wednesday's win, rookie center Deandre Ayton was still -- well -- treated like a rookie.

While talking to the media after the Suns' 121-100 win over the Mavericks on Wednesday night, Ayton was forced to interrupt his post-game interview session when veteran Trevor Ariza chimed in.

"Where the towels at, rook?" the 33-year-old Ariza yelled at the 20-year-old Ayton, who promptly got up and grabbed a bunch of towels for his older teammates.

"What were you saying about our vets again?" Ayton deadpanned after sitting back down.

The Phoenix Hillcrest Prep and Arizona Wildcats alum had a stellar debut, pouring in 18 points and 10 rebounds in his NBA debut. More importantly, the Suns are 1-0, as they won their season opener for the first time in four years.
