Training footage reveals the lightning quick speed the Mexican-American has at his disposal - arguably a department in which he trumps AJ
ANDY RUIZ JR will look to use his blistering hand speed that he hopes will stun Anthony Joshua in New York.
Ruiz challenges for the world heavyweight title for the second time on Saturday as he takes on unified heavyweight king Joshua, 29, at Madison Square Garden.
The Mexican-American was afforded the life-changing opportunity after Brooklyn mouthpiece Jarrell Miller failed a trio of drug tests.
Ruiz has been beaten once in 33 fights, a close decision loss in 2016 for the WBO belt against Joseph Parker - a man AJ would go on to defeat two years later.
The fight has been met with scepticism due to Ruiz’s podgy frame - though the 29-year-old’s hand speed cannot be denied.
Footage of his training sessions reveal the lightning quick speed that has helped Ruiz claim 21 KO’s.
Ahead of Joshua's US debut, substitute replacement Ruiz told he will put in a better showing than past Joshua opponents and vowed: “I'm not scared”.
Ruiz said: "Carlos Takam, Dillian Whyte? I thought: 'I can do a lot better than those guys'.
"I'm an exciting fighter. People look at me and say: 'he's slow, he will get tired'. But I'm a combination fighter.
"I move, I throw punches, I go in to knock out my opponents.
"Everybody that fights Joshua has fought scared - they move around and try not to get hit. But I'm not scared of getting hit. I'm here to get hit, and hit back.
"People like watching me fight because I'm not scared and I bring a fight."
