This past Saturday night, Errol Spence (22-0, 19 KOs) became the IBF welterweight champion when he unseated  Kell Brook (36-2, 25 KOs) with an eleven round stoppage before 27,000 hostile fans at Bramall Lane in Sheffield.

The fight lived up to hype, but Spence began to take over the later rounds, by dropping Brook in the tenth round and nearly putting him away. Brook rallied and survived, but took a voluntary knee in the eleventh for the full count.

Afterwards, Brook told reporters that he received medical confirmation of a fractured left orbital bone. Brook fractured his right orbital bone last September when he was stopped in five rounds by middleweight champion Gennady Golovkin.

Spence believes the victory has now catapulted him to the very top of the welterweight division.

"Kell and myself are the most skilled fighters at 147-pounds, also the biggest and strongest so yes, I do think beating him makes me number 1," Spence, 27, told Sporting Life.

"I think we gave the fans what they wanted to see and I take my hat off to him. Kell is strong, fast and crafty - he lived up to all my expectations. He can also punch and I had to show true grit to see it out. I told you I was coming over here to take the title back to America and I did that. It's only up from here now - I want to fight [WBA/WBC champion] Keith Thurman and [WBO champion] Manny Pacquiao - my ultimate goal is to unify the titles."

Before Spence can get his hands on the other two champions, he will likely make a voluntary defense or two. Thurman just underwent elbow surgery and won't be able to fight until the end of the year, while Pacquiao is scheduled to make a defense of his title on July 1 against Jeff Horn in Australia.
