Shane Mosley: If He Is Done, What are his 5 Greatest Fights?

Shane Mosley's 18-year career in boxing has been a long road of highs and lows, but it has all led to one thing—a spot in the boxing Hall of Fame.

His unanimous decision loss to Filipino superstar Manny Pacquiao (53-3-2, 38 KO) is the last thing he needed if he wanted to reinstate his position in the fans' minds. His record drops to 46-7-1 with 39 knockouts.

Mosley is now 0-2-1 in his last three fights with the other loss coming to Floyd Mayweather Jr. and the draw coming from Sergio Mora; both in 2010.

So should the four-time world champion call it quits, or does he still have something left?

Whether or not he does, these are his five greatest fights, win or lose.

From start to finish, this was one heck of a fight.

Shane Mosley and Puerto-Rican star Miguel Cotto traded powerful blows for 12 high-paced rounds before the winner was declared. Both boxers landed exactly the same amount of punches at 248 for a total of 506 total landed punches.

Cotto walked away with a unanimous decision with the scores 115-113 across the board, but it was a close one that could have gone to either guy.

Still undefeated at the time, Cotto got the biggest win of his career over the four-time welterweight champion, who returned soon after to knock out Ricardo Mayorga.

No. 4 Ricardo Mayorga (Sept. 27, 2008)

When Shane Mosley took on Ricardo Mayorga, nobody knew what to expect. What occurred in the ring that night was surprising, yet brutal.

The scorecards through 11 can tell the story of the fight up to that point. Two judges had it scored for Mosley at 107-102 and 105-104. Despite Mayorga only landing half as many punches as Mosley, the other judge had it going his way by one point.

Basically, it was in line to end with a split-decision win for Mosley or a draw.

Mosley didn't take any chances and finally opened up on Mayorga in the last round to drop him with less than 20 seconds to go. Immediately after the ref let them continue, Mosley landed a perfect left hook right to Mayorga's jaw, knocking him out at 2:59 of the 12th round.

No. 3 Fernando Vargas 2 (July 15, 2006)

LAS VEGAS - JULY 15: Referee Kenny Bayless (C) checks on Fernando Vargas (L) after he was knocked to the canvas by Shane Mosley (R) in the sixth round of their junior middleweight rematch at the MGM Grand Garden Arena July 15, 2006 in Las Vegas, Nevada.

The first meeting between Fernando Vargas and Mosley was an action-packed fight with an indecisive ending as Vargas' face had swollen profusely. After the referee stopped the bout, Vargas was unhappy and wanted to do it again.

Four months later, Mosley got another chance at putting away the Mexican fighter away for good.

He did so emphatically when he knocked Vargas down with a perfect left hook to his head. Wobbled and hurt, Mosley quickly jumped on Vargas, and the referee jumped right back in to wave off the fight.

It was one of the biggest wins of his career and one of the best knockouts.

No. 2 Antonio Margarito (Jan. 29, 2009)

LOS ANGELES - JANUARY 24: Shane Mosley lands a punch on Antonio Margarito en route to his TKO in the ninth round after Margarito's corner threw in the towel during their WBA welterweight title fight on January 24, 2009 at the Staples Center in Los Angel

The first big fight of 2009 featured the most avoided fighter in the sport in Antonio Margarito and the biggest underdog of the sport, "Sugar" Shane Mosley.

Mosley, a 4-1 underdog, stepped up to challenge the "Tijuana Tornado," who was just coming off the biggest win of his career when he stopped Miguel Cotto in the 11th round the previous year.

The fight was one-sided, but not for the guy everyone thought was going to win.

The 37-year-old dominated the bigger man with combination punching and powerful right hands. He finally got to Margarito in the eighth with a brutal combination to drop the Mexican fighter before the end of the round.

Early in the ninth, it was all over for Margarito as Mosley unloaded on him against the ropes and got the TKO victory over an opponent who had never been stopped before.

The first meeting between Oscar De La Hoya and Shane Mosley was Ring Magazine's "Event of the Year" for 2000.

De La Hoya only had one defeat on his record to Felix Trinidad, and Mosley was unbeaten at 34-0.

It was a high-rate boxing contest with two determined boxers trying to get the last shot in.

Fast combinations and technical footwork from both boxers highlighted the welterweight matchup, and it was a great one. The 12th round is one of the most memorable final rounds of any championship fight.

Mosley earned a split-decision victory for his efforts that night, and it was well deserved.
