In his continued effort to make it back to the big show, UFC alum Joe Giannetti added another highlight finish to his reel. Giannetti (15-5-1), who was the lightweight runner-up on “The Ultimate Fighter 27,” took a short-notice fight Saturday at Cage Titans 62 in Plymouth, Mass. Up a weight class at welterweight, the risk paid off as Giannetti flattened opponent Pat Casey (10-8) with a jumping karate-style switch kick to the face. A couple hammerfists later, the fight was over at 2:12 of Round 2.
