While Martinez might be finished -- although he has one fight remaining on his HBO contract -- Cotto looked reborn. He lost back-to-back junior middleweight title fights to Floyd Mayweather Jr. and Austin Trout in 2012, hooked up with Roach, and bounced back with a third-round knockout of Delvin Rodriguez in October. But Martinez, a stalwart top-five pound-for-pound fighter for years, is no Rodriguez.
"I thought he was absolutely sensational," Top Rank's Bob Arum, Cotto's promoter, said. "I was saying to myself, 'What a waste that he didn't get to Freddie earlier.' And the way he did it, he fought like a perfect fight. He just blew him out.
"I think Sergio probably was better a number of years ago. You can't take a layoff like that and fight a guy with the skill and the stamina that Cotto has. No way you can do that."
Arum said Cotto's return is being planned for either Dec. 6 or 13 at Madison Square Garden, depending on the arena's schedule.
Arum said he would soon talk to one-time rival promoter -- and now reconciled pal -- Oscar De La Hoya of Golden Boy about a showdown with former junior middleweight titlist Canelo Alvarez, which would be a megafight between the most popular active Puerto Rican and Mexican fighters, and that is one of boxing's classic national rivalries.
"Canelo is a possibility if he gets past [Erislandy] Lara [in July]," Arum said. "Next? I don't know. But after that, next year, is certainly a possibility."
Arum also said even middleweight titlist Gennady Golovkin -- who defends his belt July 26 at MSG against former titlist Daniel Geale -- might be an option.
After Cotto's historic and unexpected domination of a great champion doesn't it seem like anything is possible?
