‘Showtime’ had Lo Greco on the canvas in a dominant victory as the 25 year-old completed a shut-out with cards coming back from the judges reading 100-88 (twice) and 99-89 after ten rounds.
Ohio’s Porter took his record to 21-0-1 in the process of the one-sided win and could potentially be in line for a welterweight world title eliminator next up after improving his ranking in superb style.
Also on the Peterson v Matthysse undercard, British duo Anthony Ogogo and Haroon Khan had no trouble in taking their respective records to 2-0 in what was their American debuts on the Showtime broadcast.
Olympic bronze medallist Ogogo won every round of six against Edgar Perez, whilst Khan blasted out a hapless Vincente Medellin in just under one minute with some accurate shots to head and body.
