Anthony Joshua has said he put on a masterclass, after regaining his world titles against Ruiz Jr.
Ruiz shocked the boxing world, when he stopped Joshua in seven rounds on June 1 in New York.
But the Mexican-American handed back the IBF, WBA and WBO heavyweight world titles in a unanimous decision, when they met for a second time in the Diriyah Arena, Saudi Arabia.
Joshua told Sky Sports: “I respect Andy and his trainer so much. I wanted to show the sweet science of this lovely sport.
“Stay hungry, stay humble. I’m humble in defeat and will stay humble in victory.
“Careers are all about experience, I took my loss and bounced back, anyone can do it. You want me to retire and give up?”
