The source is the same as below, the Dave Meltzer article at Yahoo. I didn't have time to elaborate on this part of it before, but I want to now.
Adding intrigue to the Mayweather fight, which may be held at the MGM Grand Garden Arena in Las Vegas, is that Floyd Mayweather Sr. has agreed to train De La Hoya for all three fights this year.
De La Hoya said the third fight would "absolutely" be the final one of his career. "I can't turn back the clock," he said.
Figuring out Oscar's retirement opponent is just as intriguing, if not moreso, than figuring out his tune-up opponent in May. My idea?
Tito Trinidad, no matter what happens tonight against Roy Jones, Jr.
The Trinidad loss is still the one that most sticks in Oscar's craw, as he felt he won the fight. But it's also the fight that left him with the least public respect and admiration in his entire career. He's lost other fights -- Mayweather, Hopkins, Mosley on two occasions. All to great fighters. But in those fights, he fought. Only Hopkins was able to knock him out, with the crushing body punch. It was the fight that proved Oscar de la Hoya is no middleweight.
He pushed Mayweather and Mosley, two of the three most purely talented fighters of the era (along with Jones, in my opinion) to the limit in all three fights.
You'll recall Oscar-Tito for being a de la Hoya clinic early on, most likely. Almost all of us felt that way. But he ran away from Trinidad down the stretch. Literally would not fight him. I think you can argue that Oscar won the fight, a contrast to his debated decision wins over Ike Quartey and Felix Sturm, two bouts that many felt de la Hoya lost. His only loss that I think is truly debatable is that against Trinidad.
Oscar-Tito II would be a perfect capper in the careers of both men. For as much else as both did, their fight is still talked about, despite that it was somewhat disappointing in terms of action, particularly on Oscar's side after he started coasting. What was then the biggest non-heavyweight fight of all-time would still be a big fight now, and that would be true if Roy Jones knocks Trinidad out in the first round.
Who else is there? A third bout between de la Hoya and business partner Mosley isn't going to happen, because they work together too closely.
I think the path works very well: A tune-up fight, a rematch with the best pound-for-pound fighter in the world, and then a goodbye with an old rival, where there is unfinished business, no matter how old the business is.
If the three fights in 2008 are definitely the end of Oscar de la Hoya's in-ring career, boxing as a whole owes him a huge debt of gratitude. When the heavyweight division ate itself, it was Oscar who did the most to keep the sport alive and kicking. You may not be his biggest fan, but he's truly been Golden for the sweet science. Without him, who knows where boxing would be?
