Karim Mayfield: I was robbed against Eyubov

Karim Mayfield - Having had a week to consider his controversial decision loss to Kazakhstan's Bakhtiyar Eyubov (11-0, 10 KOs), San Francisco welterweight Karim Mayfield says he's not happy.

Having had a week to consider his controversial decision loss to Kazakhstan’s Bakhtiyar Eyubov (11-0, 10 KOs), San Francisco welterweight Karim Mayfield says he’s not happy.

Fighting in the opening fight on ShoBox: The New Generation® last Friday, August 19, at Rhinos Stadium in Rochester, New York, Mayfield (19-4-1, 11 KOs) appeared to outpunch and outwork his unbeaten foe, especially in the last four rounds. Despite having the statistical advantage – and winning in the eyes of the Showtime commentators, most of the ringside media, the fans in attendance and a worldwide outcry – Mayfield found himself on the wrong side of a 10-round split decision (95-94 twice for Eyubov and 95-94 for Mayfield) at the end of their exciting battle.
