The Legends Sports Universe Boxing Federation's lightweight title was originally contested through a four-man tournament featuring Jack McAuliffe, Benny Leonard, Jose Luis Castillo and Julio Diaz.

McAuliffe stopped Diaz via sixth round TKO in one semifinal while Leonard got the better of Castillo via split decision on the strength of landing more than half of his punches in the bout.

The presumed bout for the title happens and lives up to billing. But the presumption Leonard would take on McAuliffe from a distance proves incorrect, as Leonard proves the aggressor en route to a unanimous decision victory to become the first LSUBF lightweight champion.

Leonard would cement his claim to the strap with three unanimous decision victories in his first year as champion, taking out Battling Nelson, Castillo and Joe Gans over the first 12 months.

Diaz's camp long complained his stoppage loss in the semifinal was a bad stoppage, and Leonard gave him a shot at the belt, defeating him by unanimous decision as well in February.

After four defenses in 14 months, Leonard didn't fight for eight, and when he did it would be a rematch against Joe Gans.  Leonard showed no sign early of being ring rusty when he dropped Gans in the first, but he'd be cut in the sixth and with the cut getting worse as the fight went on, there was concern for a stoppage. Once Leonard reached the 15th - the champion and again, albeit close on cards - it was assumed he'd hold on. But the ringside physician ordered the bout stopped, handing Gans the TKO win and the lightweight title with 1:15 left in the bout.

Gans would wait eight months to make his first defense, stopping David Diaz by TKO in the 8th. He'd then have to give Leonard his long-awaited rematch.

This time it would end in the 13th...and with the same result. Leonard ahead on all cards is deprived of a victory as the bout is stopped because of damage, swelling and two cuts around his left eye. This stoppage is more legitimate than the first, but still a bitter pill for Leonard to swallow. Gans won't have to fight him again for at least a year, and that's only if Leonard is the #1 contender.

New to the Top 10 are Jimmy Carter, Tony Canzoneri and Lauro Salas.
