Sources: Canelo vs. Zurdo world title unification possible in 2019

Cinco De Mayo weekend could be an all Mexican showdown in Las Vegas.

Earlier this month, Canelo Alvarez, the unified middleweight champion and boxing's top attraction, moved up one weight class and annihilated Rocky Fielding to the body to win a secondary super middleweight world title by third-round knockout. The bout was Alvarez's first in New York, a venue he had always wanted to headline. Moreover, it also marked the first fight of his record-breaking five-year, 11-fight, $365 million deal with new sports streaming giant DAZN.

Sources have informed FightNights.com that Canelo could stick around the division and face unbeaten WBO titlist Gilberto "Zurdo" Ramirez, a southpaw, in a world title unification on May 4 T-Mobile Arena.

Ramirez (39-0, 25 KO's), of Sinaloa, who said he would move to 175 pounds after outpointing Jesse Hart in a rematch on Dec. 14, is likely to put that plan on hold if he can land the Canelo fight, one that he has expressed interest in for the past several months.

"Canelo, here is my title, come and get it," Ramirez, 27, said in October.

The 28-year-old Alvarez, of Jalisco, despite being just one year older than Ramirez, has the better resume. Canelo won the most significant bout of his career in September, when he edged Gennady Golovkin to win the unified middleweight world title in a rematch of last year's highly controversial split draw. Moreover, Alvarez has also fought Floyd Mayweather, Miguel Cotto, Erislandy Lara, and Austin Trout.

Since winning the title by shutout decision against former champion Arthur Abraham in April 2016, Ramirez has faced Max Bursak, Jesse Hart (X2), Roamer Angulo, and Habib Ahmed -- none of whom have a skill set remotely close to Canelo's.

If Alvarez unifies at 168-pounds, it will be interesting to see if a possible trilogy match with Golovkin ever takes place.
