The first fight between the two champions was scored a draw and now the two look to settle the score once and for all following what some thought was controversial judging on the scorecards. 

When previewing the fight on JABS, DAZN Boxing analyst Sergio Mora believes Charlo will produce a dominant display against the WBO 154lb champion. 

"Jermell Charlo that’s who I’m picking," Mora predicted. 

"The second time around a champion knows what they’re expecting.

"Castano as good as he is should have got the nod the first time around, I just think this time around is going to be different, the fight’s in LA and hopefully we get some better judging.

"It’s going to be a close fight, but the judges aren’t going to be needed, I think we see a knockout by Jermell Charlo."

Chris Mannix saw why Mora is backing the WBA, WBC and IBF champion to get the win, but he believes Castano's boxing ability will be the difference in this rematch. 

"I don’t disagree that Jermell Charlo is a big-time threat to score a knockout," Mannix said. 

"He’s the bigger puncher, and yes he’s going to be more prepared for that kind of aggressive style from Brian Castano the second time around.

"But Sergio I’ve seen a lot of Castano over the last few years. You and I were ringside in Southern California a couple of years ago when Castano went to war with Patrick Teixeira to win his title at 154.

"Before that he gave Erislandy Lara hell in a fight in New York, a fight he probably should have won by decision as well, he knows how to fight against these taller fighters.

"In that first fight he got inside Jermell Charlo a lot, he was landing big combinations on Jermell Charlo and to your point if that fight doesn’t take place in Texas, the home state of Jermell Charlo, I think Castano would have got the decision and maybe we wouldn’t be here having this discussion.

"The second fight moved to California, presumably Castano will get a fair shake by the judges and I think if he can avoid that one big shot which I think he can, he is going to outbox Jermell Charlo and win by very close decision."
