Mets hurler R.A. Dickey says he and a “Jedi council of knuckleball pitchers” will meet at the Tribeca Film Festival’s Drive-In section tonight. The righty and former players Tim Wakefield, Charlie Hough and Jim Bouton will hold a pitching clinic at a Battery Park premiere of the documentary “Knuckleball!” — about the slow pitch — by Ricki Stern and Anne Sundberg (who’ve tackled such other confounding topics as Darfur and Joan Rivers). “We’re definitely different,” Dickey told us. “The pitch is viewed by a lot of people as freakish, capricious and tough-to-master. It’s the ugly stepchild of pitches. But it’s something we’ve embraced instead of being ashamed of.
