Floyd Mayweather Jr. proved long ago to have the blueprint to beat Saul ‘Canelo’ Alvarez.

Nearly nine years later, the Hall of Fame former pound-for-pound king had a hunch that the sport’s current ruler was due for a fall.

Mayweather literally cashed in on Alvarez’s points loss to WBA light heavyweight titlist Dmitry Bivol (20-0, 10KOs), clearing a $42,500 profit from a $10,000 bet placed on Saturday’s DAZN Pay-Per-View main event from T-Mobile Arena in Las Vegas. The former five-division champion rolled with Bivol, who was a +425 betting underdog according to Silverton Sportsbook when Mayweather placed the bet at 2:08 p.m. local time—less than seven hours prior to the opening bell.

“Easy pick up,” Mayweather commented on his verified Instagram account, literally minutes after Bivol’s upset win over Alvarez to defend his WBA title.

Mayweather took home $52,500 in total after placing the $10,000 for Bivol to win, regardless of means of victory.

The loss was the first for Alvarez since dropping a strangely scored majority decision to Mayweather in their September 2013 WBA/WBC junior middleweight championship fight at MGM Grand Garden Arena in Las Vegas. Mayweather won on the scorecards of judges Dave Moretti (116-112) and Craig Metcalfe (117-111), while C.J. Ross (114-114) was rightly criticized for scoring a draw.

Moretti was one of three judges for Saturday’s main event, joined by Tim Cheatham and Steve Weisfeld in all scoring the contest 115-113 in favor of Bivol, who trailed 40-36 on all three scorecards before winning seven of the final eight rounds to preserve the win and avoid a massive scoring controversy.

Alvarez ended a sixteen-fight unbeaten streak (15-0-1, 9KOs) with the defeat, having won titles at middleweight, super middleweight and light heavyweight along with a second junior middleweight title reign in between his losses to Mayweather and Bivol.

Mayweather (50-0, 27KOs) was already a five-division champion by the time he faced a then 23-year-old Alvarez. The unbeaten all-time great would go on to win five more official bouts to close out his career at a perfect 50-0 upon retiring for good following a tenth-round knockout of UFC superstar and boxing debutant Conor McGregor. Their August 2017 superfight came nearly two years after Mayweather’s twelve-round win over Andre Berto in September 2015, at which point he claimed to be done with the sport.

Mayweather has since fought in two exhibitions and is preparing for a third as he faces ‘Dangerous’ Don Moore on May 14 in Dubai. He also continues to oversee his Mayweather Promotions company along with several other business ventures—including a nationwide chain of Mayweather Boxing + Fitness workout facilities—while remaining an avid gambler on various sports.
