The "Next Knuckler" experiment is officially over.

The Diamondbacks on Wednesday released pitcher Josh Booty, the former Marlins infield prospect, LSU quarterback and winner of the MLB Network reality show "The Next Knuckler."

"We thoroughly enjoyed being a part of 'The Next Knuckler' and having Josh in camp," D-backs president and CEO Derrick Hall said. "We gave him an opportunity to make the team, but it unfortunately did not work out for him. He's a terrific guy and was a display of class his entire stay."

Booty, 37, won an invitation to D-backs camp by beating fellow ex-quarterbacks Doug Flutie, Ryan Perrilloux, David Greene and his brother John David Booty on the MLB Network show, which featured former big league knuckleballers Tim Wakefield and Charlie Hough teaching the contestants to throw a knuckleball.
