Vaughn (6-5, 200) is ranked the No. 13 player in the Class of 2014 by Scout. He had drawn a scholarship offer from the Wildcats earlier his year, but had seemingly dropped off UK's radar after the summer evaluation period.
On Tuesday, UK assistant coach Orlando Antigua was in Las Vegas to see Vaughn, a Minnesota native, play at Findlay Prep, as first reported by Scout national basketball analyst Evan Daniels. The Cats also got a look at one of their top 2015 targets, center Stephen Zimmerman, while in Nevada.
Vaughn, who plans to sign in the spring period, has expressed strong interest in North Carolina, Iowa State and UNLV as well as Baylor, Minnesota, Kansas and Arizona.
Scout national analyst Rob Harrington broke down Vaughn's game: "Scorer. You can't always perfectly describe those guys, but you know them when you see them. Vaughn simply knows how to put up big numbers.
"He's not the most efficient player, but has that extra explosive quality that enables him to transcend pace and context and dominate for stretches. Vaughn also has been an effective offensive rebounder who picks up some easy ones on putbacks. He's also a potentially tough wing defender."
