Mosley vs. Alvarez Results: Devastating Loss Proves Shane Mosley Must Retire

On a night where Floyd Mayweather Jr. and Miguel Cotto stole the spotlight, it was the Shane Mosley and Saul Alvarez fight that deserved the attention.

In a fight that went the distance, Alvarez was declared the winner by unanimous decision, as this may have well been and should be the last bout that Mosley takes part in. It is time for Mosley to remove the gloves and retire from the sport of boxing, as the loss was a telling one.

For his career, Mosley has proven himself to be one of the greater boxing talents of our generation. He has taken down the best of the best and taken on each and every impressive talent in the sport.

He may have lost four of his last seven, yet three of those matches came against arguably the best fighters in the sport. There was of course the most recent loss to Alvarez, who is yet to lose a fight, a loss to Cotto before he lost a bout, and Pacquiao after lasting all 12 rounds.

Talk about a strong list of talents to deal with.

For having gone up against these skilled fighters, Mosley puts himself in a completely different light. In today's game, there is now an issue with the greats not facing each other, as is the case with Pacquiao and Mayweather. Both, selfishly, have too much pride to put their records and careers on the line for the fans.

Yet, it is fighters like Mosley and Cotto for example, that have taken on both Mayweather and Pacquiao and were not afraid of putting their careers on the line.

Mosley, a top-notch fighter and now 40 years old, is getting to the age where there is no doubt he needs to leave the sport. He continues to impress fans and analysts of the game, but his body can only take so much at his age.

The age factor is ultimately the biggest indicator that Mosley has to call it quits. It has been impressive enough that he has lasted as long as he has and is still performing at a top level.

He was a true boxing talent, a pleasure to watch, and a boxer who now knows as well as others do that it is time for him to leave the sport behind.
