O’Sullivan: This was a fight I just had to win

The Leesider beat Berlin Abreu at the StubHub Centre in LA on Friday, 24 hours before Gennady Golovkin knocked out Vanes Martirosyan at the same venue to equal Bernard Hopkins’ record of 20th successive title defences.
The Kazakh is now likely to go for a record 21st title defence against Mexico’s Saul “Canelo” Alvarez after retaining his WBA/WBC/IBO/IBF belts.
