Principality Stadium, Cardiff, Wales - Hot welterweight prospect Josh Kelly (6-0, 4 KOs) took a big step up in class and passed the test with flying colors as he won a solid ten round unanimous decision over former IBF junior middleweight world champion Carlos Molina (28-9-2, 8 KOs) to win the vacant World Boxing Association International welterweight title.

The judges scored the contest 98-92, 99-92, 98-92 in favor of Kelly.

The contest was part of the undercard to the heavyweight unification between Anthony Joshua and Joseph Parker.

Molina, at only 34-years-old, has seen much better days. Coming into this fight, Molinahad lost two in a row - to undefeated prospect Carlos Adames and French contender Ahmed El Mousaoui.

His career began a downward spiral not long after winning the world title from Ishe Smith in September 2013. He lost the title in his first defense the following year to K9 Bundradge, and then won six in a row against overmatched competition before going on a losing streak.

Kelly, an Olympian who made his pro debut in April 2017, was dictating the pace from the start of the contest. He was very much in charge, landing a hard jab that was pushing back the head of Molina.

Molina would land punches here and there, but none of them had any effect on the younger man. Kelly seemed to rattle Molina a bit in the eight round after landing an uppercut to the chin and a series of body shots. He was unable to really follow-up as Molina was defensive and staying away from further counters.

Kelly closed out the tenth and final round by working his jab, landing solid punches and coasting the rest of the way as he was obviously way up on the cards. Molina never showed any urgency to change the tide. He was a few steps behind and had a lot of trouble catching up to the younger man all night.
