Diego Corrales vs John Brown

In his first IBF junior lightweight title defence, Diego Corrales (30-0, 0 KOs) maintained his unbeaten record with a unanimous decision over John Brown (20-7, 0 KOs) at Oregon's Chinook Winds Casino on December 4, 1999. Judge Glen Hamada's 116-112 scorecard reflected the champion's control throughout the twelve rounds.

The victory marked another setback in Brown's pursuit of world honours following his eighth-round TKO loss to Shane Mosley for the IBF lightweight title earlier that year. Brown would continue chasing championship glory, facing Steve Forbes twice for the IBF super featherweight belt in 2000, losing both encounters.

For Corrales, the win solidified his position in a competitive 130-pound division, demonstrating his ability to handle experienced opposition. The HBO-televised Main Events promotion showcased both fighters comfortably, making the weight—Corrales at 130 pounds and Brown at 129 pounds.

Referee Mark Nelson oversaw this technical chess match, ultimately proving another stepping stone in Corrales' developing championship career.
