Josh Taylor made history as he defeated Jose Ramirez to become the undisputed junior welterweight champion.

Taylor defeated Ramirez by unanimous decision, to walk away with the WBC, WBA, IBF and WBO titles following an action-packed battle at the Virgin Hotels Las Vegas on Saturday.

The Tartan Tornado was way up after the first seven rounds. He scored two big knockdowns in round six and round seven, with Ramirez shaken up as he got back to his feet from the big uppercut in the seventh.

Ramirez was forced to dig deep and he rallied in the championship rounds, putting his punches together and trying to turn the tide.

He was able to make the contest closer with the judges, but not enough to walk away with the win.

After the smoke had cleared, the three official judges scored it 114-112, 114-112, 114-112, meaning in just his 18th professional fight Taylor becomes one of the few men in history to become four-belt undisputed champion.

“I’m ecstatic. I’ve trained my whole life for this and dreamt of it so many times over. I’m so happy and over the moon," Taylor said.

“Nothing but love for Ramirez. I meant no disrespect this week. It was just mind games to get him more eager to jump in. We said all week we will use his aggression against him and we got in his head. There is nothing but respect there though, he’s a great champion and an ambassador for the sport.

“The scorecards should have been a bit wider. I wasn’t too happy with the selection of judges but we were still confident of winning the fight. There is a new warrior king on the map and he’s from Scotland!”
