Looked to me like Gazdic connected on his last punch for a knockdown, but up to that point Peluso was landing some good shots, and Gazdic was kind of out of range.
I'll call it a draw.
But, that's the kind of fight, if you're in Gazdics position and keep punching when it's easy for the other guy to counter, that can end up with a KO/TKO.
