Jermell Charlo (34-1-1, 18 KOs) vs Brian Castaño (17-0-2 12 KOs)

Undisputed Super Welterweight Championship, 12 Rounds

The rematch for the undisputed title at 154lbs was our main event tonight on Showtime. The first fight was a fascinating clash of styles, and the second fight was a continuation of that. It was the battle of the activity and combination punching of Castaño, pinned against the powerful counterpunching of Charlo. Jermell Charlo made sure to be more active in the early rounds to not let Castaño build up an early lead as he did in the first matchup. Castaño started to have more success in the middle rounds, as his right hand began to land more often over Charlo’s jab. Charlo landed a huge counter left hook in the 7th round which slowed Castaño down and forced him to lower his output. A left hook on the inside dropped Castaño to the canvas in round ten; and, after a ferocious attack and a left hook to the body, Castaño was dropped for the second time in the round. The fight was then waived off, and Jermell Charlo became the first undisputed champion of the four belt era in the 154lb division. It will be interesting to see what Charlo does now that he holds all of the belts at 154lbs. Fights with WBO top ranked contender Tim Tszyu and interim WBC champion Sebastian Fundora would be great fights that can be made under the PBC banner. With stablemate Errol Spence Jr. potentially moving up to 154lbs in the near future, a potential jump to the middleweight division is also a possibility for the newly minted undisputed champion. Charlo improves to 35-1-1 (19 KOs), while Castaño falls to 17-1-2.

Jaron Ennis (28-0 26 KOs) vs Custio Clayton (19-0-1 12 KOs)

IBF Welterweight Title Eliminator, 12 Rounds

Jaron Ennis showed once again tonight why he is considered by many to be the future of the welterweight division. He met the undefeated Custio Clayton tonight in an IBF title eliminator in Showtime’s co-main event of the evening. He got right to work against the former Canadian Olympian as his jab backed up Clayton in round one. Clayton never was able to get his hands going, and a huge right hand from Ennis put him down and out in the second round. With the win in an IBF title eliminator, Ennis makes it known that he is looking towards a potential title shot against Unified Welterweight Champion Errol Spence Jr. If Spence is able to get a fight made with WBO Champion Terence Crawford for undisputed at 147lbs for later this year, then a Keith Thurman fight would be the perfect opportunity for Ennis to continue to build up his name as he gets closer to a world title. Ennis improves to 29-0 (27 KOs), passing yet another test with flying colors, while Clayton falls to 19-1-1 with the defeat .

Kevin Gonzalez (24-0-1 13 KOs) vs Emanuel Rivera (19-2 12 KOs)

Kevin Gonzalez wins via Unanimous Decision (98-92, 97-93, 96-94)

Opening up the telecast tonight on Showtime was a 10-round super bantamweight contest between Kevin Gonzalez of Mexico and Emanuel Rivera of Puerto Rico. The two fighters traded blows in an entertaining start to the bout. Both men had success on the inside, landing punches to the head and to the body of their opponent. The sixth round was great action as it saw both men land serious power punches. Rivera was always in the fight, but the speed and combination work of Gonzalez over the last few rounds was the difference. Gonzalez will need to tighten up his defense as he moves up the ranks, but being only 24 he still has plenty of time to do so. Gonzalez improves to 25-0-1 with the victory in his US debut , while Rivera drops to 19-3.
