About Greg Valentine
Greg Valentine, also known as Jonathan Anthony Wisniski, is an American retired professional wrestler, better known as Greg "the Hammer" Valentine. He is the son of wrestler Johnny Valentine. Valentine then formed a tag team with Ric Flair, with whom he twice won the NWA World Tag Team Championship and held the NWA Mid-Atlantic Tag Team Championship (between June 30 and August 22, 1977). Wahoo had cost Valentine and Flair their first tag team championships (Wahoo, the then-nemesis of Flair, had been the special referee in the steel cage match), so Valentine was eager for revenge. In January 1982, Valentine met Backlund yet again, this time in a steel cage, for the WWF Heavyweight Championship at the Philadelphia Spectrum, which Backlund won. He held the title until November 24, when he was beaten by Flair; Flair became one of Valentine's main opponents in the Mid-Atlantic territory.
