Ladies first, Amanda Serrano joins Manny Pacquiao and Oscar De La Hoya as 6-division champions with her UD victory against Yamila Reynoso.

Featherweight prospect Chris Colbert wins another decision against Fatiou Fassinou after taking Dulay's 0 back in April. They call Colbert "Lil B-hop." The kid is a joy to watch for any fans hitting and not getting hit.

Both of those fights were on the untelevised part of the undercard of the Shawn Porter vs Danny Garcia fight (you can watch it here: https://www.youtube.com/watch?v=S3_gN06-kOc ), which Porter won due to outworking the more accurate Garcia.
It was announced some weeks ago that Spence would be fighting the winner of that fight, but Porter doesn't really appear to want to get in the ring very soon imo. I don't really blame him, but he gotta give up that belt.

Adam Kownacki beats Charles Martin in a very spirited heavyweight battle on the televised part of the Porter/Garcia undercard. Also on that card, Yordenis Ugas dominates Cesar Barrionuevo for a UD.

Amir Khan beats Samuel Vargas but proves his chin still ain't shit by getting floored in the 2nd. He did knock Vargas down twice tho. Not sure why he's had the nerve to call out Spence or Crawford if this level of comp is giving him problems.
