Consider Rodrigio Lidio a knockout machine. Lidio, making his LFA debut, won his fourth consecutive fight by knockout Friday at LFA 111, finishing Pitbull Brothers’ Arthur Lima in their lightweight bout at Upper Arena in Rio de Janeiro. The knockout came just 23 seconds into the second round, and it was a spectacular one as Lidio (12-2) connected with a left hook – and that was all he needed as Lima (9-2) fell to the canvas and was done after that one punch.
