LAS VEGAS (TheBlaze/AP) -- If there's a secret to earning the most money when punching the clock the fewest times (figuratively speaking, of course), boxer Floyd Mayweather Jr. has uncovered it in a big, big way.

On Saturday night he'll make at least $41 million to fight undefeated Mexican star Canelo Alvarez, bringing Mayweather's take for the year in two fights to a whopping $73 million.

Those two days at the office make Mayweather the highest-paid athlete in the country, far outshining Miami Heat star LeBron James, who made $56.5 million this year in salary and endorsements.
Of course the undefeated 36-year-old welterweight does a bit more than simply step into a ring two times a year to garner his success, but you can't help but notice all that he's tangibly reaped as a result.

He spends big money, sometimes as much as $200,000, for handbags for his female friends. Then he buys them something called a "Baginizer" to make sure everything inside is organized.
He's not invincible financially...he does lose at the sports book. Mayweather loves to post pictures on Twitter with six-figure wins on his bets, but acknowledged this week he lost a big bet Monday night on the Houston Texans.
He's in business with a Chinese company that manufactures his The Money Team apparel. His business partner is named China Mike "because everybody's got to have a nickname."
He can name every car on duPont Registry, his favorite online shopping site. He owns many of them, almost all in white and in fleets at homes in Las Vegas, Miami and Los Angeles.

Mayweather has a nickname, too, though it's different than the one he had when he first started boxing professionally 17 years ago. He was Pretty Boy Floyd then, before America discovered him as the villain they would pay to watch and before he had the cars and the mansion on a golf course.

What's his nickname these days?
Money May, of course.
But his bling-infused moniker seems well deserved, as Mayweather has delivered wins in all 44 of his fights. People who don't like him will pay to see if he'll lose, and his fans will reach into their pockets to cheer him on for another win.
This Saturday's pay-per-view will cost a record $75, leading promoters to boast that this could be the richest fight ever, surpassing the 2007 bout between Mayweather and Oscar De La Hoya.
That may or may not happen, but the idea that Alvarez might be the one fighter with the stuff to finally beat Mayweather has made this one of the most anticipated fights in years.
Mayweather's whopping $41 million guarantee is made possible by pay-per-view sales, and ringside seats that sell for $2,000. Still, promoters say they hope to get near the 2 million mark from pay TV,, helped largely by the Hispanic market backing Alvarez.
Oddsmakers make Mayweather a 2½-1 favorite against Alvarez, the 23-year-old redhead who is Mexico's biggest sporting hero and undefeated in 42 fights. But the level of his competition is nowhere near that of Mayweather, and he will be fighting at a catch weight of 152 pounds, 2 pounds below the 154-pound mark where he holds his title belts.
"I've studied a lot of his fights," Alvarez said. "I'm not just ready, I'm ready to win."
Mayweather was a less-than-fashionable 37 minutes late to the final prefight press conference Wednesday at the MGM Grand hotel casino, not that it mattered. It was such a low-key affair that even those on the dais seemed to want to be somewhere else.
"I've been here before. I know what it takes," Mayweather said. "I was born to be here, born to be at this level."

And despite the challenge his newest opponent presents, Mayweather is the star of this fight, just as he has been for almost every bout of his career.
"I feel like I'm the last of my breed," Mayweather said. "I earned it the hard way."
