According to a source, Shayok, a 6-foot-7 forward out of Blairstown (N.Y.) Blair Academy, made a pledge to Tony Bennett and his staff Tuesday evening.
Shayok originally signed with Marquette, but received his release from the Golden Eagles on April 11th. Shayok took a visit to Virginia the first time he went through the recruiting process.
Shayok's high coach Joe Mantegna also confirmed the news to Scout.com.
"UVa was Marial's first visit on Labor Day weekend," Mantegna told Scout.com. "Marial's family trusted Tony implicit and his staff was relentless."
Virginia assistant Ron Sanchez was the point man on Shayok's recruitment. This is the second player he's reeled in from Blair Academy. Current UVa player Mike Tobey played at Blair Academy as well.
"He did a great job recruiting Tobey and Marial," he said. "We all trust Ron and of course coach Bennett."
Shayok is regarded as a three-star prospect.
