The Scot put his WBA and IBF super lightweight titles on the line against WBC and WBO champion Jose Ramirez, and defeated the Mexican-American on points in Las Vegas.
The victory over the previously unbeaten Ramirez (26-0, 17KOs) means Taylor become Scotland’s first undisputed world champion since Ken Buchanan.
Here’s how the Prestonpans fighter progressed from Commonwealth Games champion who learned his craft in Edinburgh’s Lochend Gym to boxing greatness.
