Terence Crawford prototypes are few and far between, which means Canelo Alvarez can only try to find fellow fighters who can mimic the prolific switch-hitting style that he will present when they meet Sept. 13 at Allegiant Stadium in Las Vegas on Netflix.

Topping the list of the undisputed super middleweight champion’s sparring partners for this camp has been former unified welterweight champion Jaron “Boots” Ennis and undefeated Cuban middleweight knockout artist Yoenli Hernandez.

“Sparring is very important to get ready for a fight. Obviously, they need to be as good as my opponent,” Alvarez said on Netflix's two-part countdown program documenting the buildup to the fight.

"I enjoy sparring the most. I can spar every day, but [coach Eddy Reynoso] doesn't like it. … [Crawford is] a really good fighter, and this is a challenge for me. It's different. We need to spar with both southpaws and right-handers.

"Everybody has issues with that kind of style. But I'm working for that. And I have the experience to face every style now. I'm different. I have everything to lose because he is coming up two weight classes. But I always like to challenge myself.”

Alvarez (63-2-2, 39 KOs) is undefeated against the seven southpaws he's faced over his last 56 professional fights. But he’s fought just two of them in the last 10 years.

The last time Alvarez faced a lefty was when he dropped, bloodied and bruised John Ryder en route to a unanimous decision during a homecoming fight in Mexico in 2023. Alvarez’s other wins against southpaws during that stretch have come against Billy Joe Saunders (RTD 8), James Kirkland (KO 3), Erislandy Lara (SD 12), Austin Trout (UD 12), Ryan Rhodes (TKO 12) and Ricardo Cano (UD 12).

Crawford (41-0, 31 KOs), who called himself the “best switch hitter ever” during the buildup of the bout, can certainly make things uncomfortable for Alvarez despite being undersized.

“Terence Crawford is one of the best fighters. But me, too. That's why I took this fight. You can see the magnitude of the fight,” Alvarez said. “He doesn't have the confidence, he doesn't have that 100% that he can do it. I'm going to do it. I am a winner. I'm going to win. I can feel it. …

"My style doesn't change. I can do everything. I can box, I can go forward, I can counterpunch, I can do whatever I want. I think this fight is going to be one of the best fights in boxing history. Everything is involved — our legacies. It's a big moment for boxing.”
