Hours before the official weigh-in, Floyd Mayweather continues to hold a major betting advantage over rival Manny Pacquiao ahead of their “Fight of the Century” Saturday night at the MGM Grand Arena in Las Vegas.

An undefeated five-division champion, Mayweather’s still an overwhelming 10/21 favorite to beat his from-a-distance rival Pacquaio, who’s listed as minor 17/10 underdog in the fighters’ first ever standoff.

Boxing’s most bankable stars held their final press conference Thursday, participating in the traditional stare down for photos, but showing little real animosity ahead of what’s expected to be the highest-grossing fight in the sport’s history by every measure.

“Nothing personal. He’s going to do his best, I’m going to do my best on Saturday to put our name in boxing history,” Pacquiao told reporters. “But the most important thing, I’m hoping that after the fight, we can have a conversation with Floyd about sharing my faith in God. We can inspire more people, especially those children who are looking to us and supporting us.”

Ever the showman and promoter, Mayweather didn’t address Pacquiao’s topic of religious conversion but focused on how he believes the fight will go down in boxing lore.

“It’s time to fight now,” Mayweather said. “You guys came out here to see excitement, you guys came out here to see a great event, and I think that’s what both competitors bring to the table: excitement.

“The biggest fight in boxing history.”

Since the mega-fight was announced back in February, the 38-year-old Mayweather’s held the distinction as the heavy favorite and odds makers largely believe he will control the tempo in route to the 48 th victory of his career.

The over-under on the total rounds continues to stand at 11.5, meaning bettors and book makers think Mayweather and Pacquiao will go the full 12 rounds. The odds the fight goes the distance are currently at 10/31, and the under is set at 12/5.

A decision in Mayweather’s favor, a result he’s attained in his last five fights and 20 times over the course of his 18-year career, is set at 10/13 odds. A knockout, something Mayweather hasn’t achieved since he sent Victor Ortiz to the matt in 2011, is at 11/2.

The powerful Pacquiao, who’s left 38 opponents unconscious in 57 career wins, seems more likely to prove victorious via decision at 15/4. A knockout in the Filipino star’s favor is set at 17/4.
