My Pick

The 32-year-old Williams won his junior middleweight the titles in May, 2019 with a unanimous decision over Jarrett Hurd and then lost them in his very next fight when he was stopped in the fifth round by Jeison Rosario. He’s now lost two fights in a row as he was beaten in his last outing by Vladimir Hernandez. Williams enters this contest with a record of 27-3-1 with 16 Ko’s.

His first pro loss came at the hands of Jermall Charlo in December, 2016 when he was stopped in the fifth round in a shot at the IBF Jr. Middleweight Belt. Williams’ lone draw was a six-round affair with Francisco Santana in 2011. He also fought a no-contest with Hugo Centeno Jr. in 2013 when the bout was halted in the fourth round due to an accidental head butt. Williams turned pro in 2010 and has 186 rounds of experience under his belt since then.

Williams stands 5-feet-10-inches tall with a reach of 72.5 inches. He has decent power with a current knockout ratio of 50 per cent and along with beating Jarrett Hurd he’s also beaten some other pretty good boxers over the years such as Nathaniel Gallimore, Ishe Smith, Joey Hernandez, Eliezer Gonzalez, Freddy Hernandez and Joachim Alcine.

As for Mansilla, he’s 36 years old and also enters the fight with two straight losses on his record, which now stands at 18-11-1 with 8 Ko’s. He’s boxed 150 rounds since making his pro debut in 2013 and has been stopped in five of his 11 losses. Mansilla has fought just once before in America and that was his last outing in September. Most of his opponents up to now have been local opposition but he did lose to Roamer Alexis Angulo in 2017 when he was stopped in the second round.

Mansilla stands 5-feet-9-inches tall with a 69.5-inch reach which means he an inch shorter than Williams and gives up three inches in reach. He’s also fought most of his career as a super middleweight. Mansilla doesn’t possess much in the way of power as his current knockout ratio stands at 26.7 per cent.


This seems to be a confidence-builder for Williams after two straight defeats as Mansilla has a shaky chin and doesn’t have much power either. He’s also 36 years old and physically smaller. Williams may have some ring rust to battle through but this is a must-win situation for him. I’m expecting him to add another W to his record come Saturday night.

Mansilla is a hand-picked opponents to get Williams’ career back on track.
