Charlo vs. Castano — The Main Event Preview


 All times listed are Eastern.

Main card: 9 p.m.

Charlo vs. Castano: approx. 11 p.m.


Fight Card (subject to change)

• Jermell Charlo vs. Brian Castano

• Rolando Romero vs. Anthony Yigit

• Amilcar Vidal vs. Immanuwel Aleem

Jermell “Iron Man” Charlo (34-1) is the unified WBA, WBC, IBF and The Ring Super Welterweight champion, and widely considered the best active boxer in his weight class. Charlo has championship boxing in his genes, as his identical twin brother Jermall is currently the WBC Middleweight champion. Jermell Charlo is riding a three fight win streak, and won titles in each of his last two fights against Jeison Rosario and Tony Harrison. That Harrison fight was extra special for Charlo, because it was revenge after Harrison gave Jermell his first career loss and took his title back in December of 2018.

Jermell Charlo has talked a lot about how that one loss shaped him, and has helped make him a more focused and determined fighter. Now he’s turned his focus to becoming the undisputed champion at 154 pounds, which would be the first time that has happened in the modern “four-belt” era. Even though Jermell is considered by nearly everyone to be the best in his class, he’s determined to take a risk to do something truly great to prove it.

Brian “Ray Sugar” Castano (17-0-1) is the WBO Welterweight champion, and even though he has held a series of other belts this is his first World Title defense. Castano won his first interim (temporary?) belt in 2016. Then he was upgraded to a regular title, which is kind of like calling a Silver Medalist a champion when there is a Super Champion or Gold Medalist out there with a higher position. But in February of this year, Castano beat Patrick Teixeira to win the WBO Super Welterweight world championship. 

Castano is Argentine, and he won his first eight professional fights in his home country. He is also undefeated, although he did settle for a draw against Erislandy Lara in 2019. An undisputed championship fight is clearly going to be the biggest fight of his life, but this is far from the only time he’s fought a big name in a spotlight matchup. Although he has twelve knockouts in his career, three of his last five fights ended in decisions. If his power can’t translate up to the elite in this division, it could be a long night for Castano. Or it could be a very short and very bad night for him too.
