They say you only get one chance to make a first impression, and David Martinez's was just what the doctor ordered at UFC on ESPN 64.
Martinez (12-1 MMA, 1-0 UFC) turned out the lights on Saimon Oliveira (18-6 MMA, 0-3 UFC) in the first round of his UFC debut in front of his home Mexico fans – and in front of his sister in his corner, fellow UFC fighter Melissa Martinez. Martinez and his sister both are doctors, as well.
Martinez drilled Oliveira with a combination late in the first round of their bantamweight bout, then put the pressure on as he stumbled backward. A vicious knee up the middle sent the fight to the canvas, and there Martinez honed in with hammer fists until a couple were on the button.
Martinez was a massive 7-1 favorite in the fight – the most lopsided odds on the card at Arena CDMX in Mexico City.
