Undefeated fighters Floyd Mayweather and Saul “Canelo” Alvarez stopped here in Washington Tuesday to promote their September 14th super welterweight world title bout, one of boxing’s most anticipated match-ups in recent years.

The fistic hoopla took place at the Howard Theatre in Washington, the second stop on an 11-city media tour.

The promotional bandwagon will also go to Mexico, where the 22-year-old Alvarez is a national hero.

“In the sport of boxing, it’s everybody’s time, and this is my time,” Alvarez said through a translator as fans chanted “Mex-i-co!” “I’m going to win.”

The red-haired Alvarez has won 42 times, with one draw, and has power with 30 knockouts.

The 36-year-old Mayweather has won all 44 of his prizefights, with 26 knockouts.

This will be the second in his six-bout, 30-month contract with Showtime Sports cable television that could pay him more than $200 million.

Mayweather is already one of the world’s richest athletes, and the fight with Alvarez could be the biggest payday yet for the boxer nicknamed “Money.”

“In every sport, there are certain rare occasions when you have the best fighting the best,” says Stephen Espinoza, executive vice president and general manager of Showtime Sports. “The Super Bowl, Final Four, the college football national championship. Sept. 14th will be one of those occasions — the two biggest stars in the sport, the two biggest fan bases.”
