Known as "Derby", Pineda turned
pro in 1986 and in 1989 took on former
Olympian Mark Breland for the
WBA welterweight title, but was
TKO'd in the fifth round. In 1991 he won the vacant
IBF Light Welterweight title by beating
Roger Mayweather with a ninth-round knockout. He successfully defended the title once before losing it by decision to welterweight legend
Pernell Whitaker in 1992. Pineda retired after the loss, but came back in 1996. == Comeback ==
