Kell Brook given Las Vegas welterweight world title shot against IBF champion Devon Alexander Brook, 26, who is 29-0, with 19 knockouts, has worked his way into being mandatory challenger to the 25-year-old American, from St Louis. Alexander defeated Randall Bailey in October to win the belt, having previously held the IBF and World Boxing Council light-welterweight titles. The southpaw has lost once in 25 fights. I've dreamt of this since I was 9 years old. Nothing's going to stop me," said Brook yesterday. Fighting for the belt in America is going to make it a lot more special. I could have had it my own way, in Sheffield for example, but to be honest I don't think he would have come over here. I've agreed to fight him in his own country and whether it was Vegas or New York, it's all going to be nice fun and games for me when I get in there anddo what I'm going to do - take him out.
