Floyd Mayweather's anemic Mayweather Promotions just took another hit by losing it's most prized prospect Jessie Vargas (19-0, 9 KO) to Top Rank Promotions.

Vargas made a career-high payday of a guaranteed $150,000 against journeyman Steve Forbes (35-11, 11 KO) on the Mayweather-Cotto undercard this past Cinco de Mayo (May 5).

Now Vargas is with Bob Arum's Top Rank, who also promotes boxing superstar and former welterweight champion Manny Pacquiao (54-4-2, 38 KO).

Top Rank also promotes current WBO welterweight champ Timothy Bradley (29-0, 12 KO).

Perhaps Vargas, being a welterweight himself, saw a better opportunity with a promoter with a wider stable of fighters.

Junior middleweight Deandre Latimore (23-4, 17 KO) is the only fighter beside Mayweather still left on Mayweather Promotions according to the promoter's official website.

Latimore lost by knockout in Round 6 to Puerto Rican veteran Carlos Quintana (29-3, 23 KO) on the Mayweather-Cotto undercard.

Mayweather has consistently referred to his promotional outfit as "the past, present and future of entertainment," but it's quickly becoming a snapshot in Boxing's past.
