Right he beat Kostya for top spot at lightwelter but lets not forget Kostya was 35 had only fought once in 23 month leading upto the fight but it was a great result for Hatton.Then he fought Maussa a man who was lucky to have a world title Hatton won but since fighting Hatton Maussa has lost twice in as many fights his last by Ko in round 1.Then came Collazo for the WBA welterweight championship to make Hatton a 2 weight champ Hatton won but struggled down the stretch many thought Collazo won the fight.Then came Urango a tough but unproven fighter for Hattons old IBF lightwelter title Hatton won but started running out of gas and ideas down the stretch again.Castillo was next up but in my opinion and many other peoples Castillo was on the downward slope infact very near the bottom Hatton produced a great win on paper KO4.Right the question is Hatton did'nt fight for a genuine title or a top flight fighter till fight 39 when he beat Kostya in his last 4 fights he has fought 3 world champs but not top flight then Castillo is Hatton really ready for Mayweather and can he really win??
