Shane Mosley and Pablo Cesar Cano promise wins for May 18 fight in Cancun

On May 18 in Cancun, 41-year-old Shane Mosley will try to score his first win in over four years, when he meets 23-year-old Pablo Cesar Cano in a 10-round welterweight bout at the Grand Oasis Resort.

Mosley (46-8-1, 39 KO) last won a fight in January 2009, when he demolished Antonio Margarito. Since then, he has looked almost helpless in losses to Floyd Mayweather, Manny Pacquiao, and Canelo Alvarez, and had a miserable 12-round draw against Sergio Mora, too.

Now reunited with his father Jack as his lead trainer, Mosley says this is the "start" of a long-term comeback, after his "retirement" amounted to nothing following last year's shutout-type loss to Alvarez:

"This is a long-term return, I'm coming for a title. I want to be champion again. I want to make history. After Cano I want one more fight and then look for a world championship. I see this fight as a new beginning for me. I have my father back [as trainer]. I guarantee you will be the same Sugar Shane Mosley [of old]. Pablo Cano is very strong, he likes to fight and that's the most important thing. I think the fight will be very good because of the styles and we also have very good chins."

Cano (26-2-1, 20 KO) has lost fights against his most notable opponents, Erik Morales and Paulie Malignaggi, but he gave a good accounting of himself in both bouts, and many felt he deserved the nod last October against Malignaggi.

He wants to be the first fighter to stop Mosley, and send Sugar Shane into an overdue retirement, for real:

"It's a great opportunity to beat a legend like Shane Mosley. It is a challenge for me. No one has ever knocked him out, and I would like to be the first. I know it will be difficult. But I'm not focused on a knockout, I'm focused on winning. When I fought Erik Morales I was young and had very little experience. Later on with Paul Malignaggi I was stronger, better prepared and I think I won the fight even though the judges gave it to him. So the third time's the charm, and this is my chance."

It's youth versus, well, Father Time. I'd say experience, but it's not like Mosley is some cerebral fighter or anything. The good news is that if Mosley can pull the trigger, the styles could indeed make for a fun fight. The bad news is pulling the trigger has been a problem for Shane since round two of the Mayweather fight in 2010. Since then, he's looked like a glass-eyed, shell-shocked, shot fighter, with the wheels turning upstairs but the body not responding like it once did.

I'd say if he can't beat Cano, it's time to hang them up, but that time has come and gone already.
