I could only give Delgado a share of the third round throughout the bout, although the Mexican did attempt to be competitive in every round to no avail. In the end, Diaz was awarded a 100-90 (twice) and 99-91 win on the scorecards and on that form is certain to be in title contention in the not too distant future.
Former world welterweight champion Joshua Clottey eased to a ten-round decision win over Jorge Silva. The US-based Ghanaian looked to have done enough to take every round and saw out a 100-90 (twice) and 99-91 decision.
At super lightweight, Keandre Gibson put in a controlling performance against Jorge Romero to take a 80-71 decision across the board, whilst 7ft heavyweight Taishan Dong moved to 4-0 with a majority decision win over Jamal Woods. Two judges gave it to the giant puncher 40-36 and 39-37 whilst a third scored it even at 38 apiece.
Rodrigo Guerrero recorded his 23rd career win by halting Arturo Badillo, whilst Armando Pina, light heavyweight Alfonso Lopez and Crescencio Ramos all stopped their respective opponents. Joseph Rodriguez made it to 9-0 by out-pointing Luis Guevara over six rounds 60-54 and 59-55, even though the third judge saw it 57-57 level.
Lightweight Curtis Meeks got the nod on two scorecards in a tight battle with Ramsey Luna to make a successful return from seven years out of action. The 31 year-old was given the eight-rounder 78-74 and 77-75 to belatedly improve to 10-1-2, whilst the third had it 76-76 even.
Also on the bill, Ryan Martin stopped Ivan Zavala in one round, although Eugene Hill’s bout was called off as his opponent pulled out.
