The classic all-action pressure fighter, ''Bam Bam'' scored three big victories this year to improve to 29-0-1. With knockouts in 10 of his past 11 fights, Rios' reputation for crowd-pleasing brawls is only growing as the stakes increase. Though he lost his lightweight title on the scale when he couldn't make weight for a Dec. 3 defense against Great Britain's John Murray (TKO 11), the 25-year-old Rios can look forward to bigger fights (and paydays) at 140 pounds.
