WBO super middleweight champion Gilberto Ramirez (38-0, 25 KOs) was involved in a snoozefest on route to a decision win over Alexis Angulo 23-1, 20 KOs) on Saturday night at the Chesapeake Energy Arena in Oklahoma City, Oklahoma.

In a candidate for fight of the year, those who crammed into the Chesapeake Energy Arena was gifted with a toe to toe war as undefeated WBO #1, WBA #2 super lightweight Alex “El Cholo” Saucedo (28-0, 18 KOs) eventually did enough to see off the challenge of WBO #7 Lenny Zappavigna (37-4, 27 KOs), stopping him in the seventh.

In a bloody affair, both were cut, Saucedo was able to score a knockdown in the third but Zappavigna fought back valiantly, battering Saucedo in the fourth but never able to find the fights finisher. Saucedo got back behind the jab in the sixth and as the eye of Zappavigna closed in the seventh his corner decided enough was enough and called a halt to an absorbing contest. Saucedo is now mandatory challenger for WBO 140lb champion Maurice Hooker.

Ireland’s Super Featherweight Michael Conlan (8-0, 5 KOs) outpointed former world title challenger Adeilson Dos Santos (19-5, 15 KOs) on route to an uneventful eight round decision. Score was 79-73.

Super Lightweight Jack Catterall (21-0, 12 KOs) continued unbeaten, handing Tyrone McKenna (16-0-1, 6 KOs) the first loss of his career by unanimous decision. Catterall was deducted a point for hitting McKenna whilst he was down in the second but regained it with a knockdown later in the same round. Catterall’s power was on show for all as he scored another knockdown in the fifth before winning by scores of 95-91, 94-93, 94-93.

Unbeaten super featherweight Jono Carroll (16-0, 3 KOs) stopped Declan Geraghty (17-3, 4 KOs) on the ninth after a barrage of punches. Time was 2:12.
