LAS VEGAS – Welcome inside the MGM Grand Garden Arena, where SI.com is ringside for Floyd Mayweather’s (alleged) final fight, against former welterweight titleholder Andre Berto. Some notes before we begin...
• Mayweather (48-0) has continued to maintain that this will be his last fight. While most, including Mayweather’s father, Floyd Mayweather Sr., believe he will fight again, Mayweather insists this is it. Strangely, that narrative has gotten little traction this week. Instead, Mayweather has attempted to convince reporters that Berto (30-3) is a dangerous opponent. Few agree, including Las Vegas, which has established Mayweather as a 30-1 favorite.
• I have covered every Mayweather fight since 2007; this is easily the most subdued fight week. The MGM Grand has lacked its usual bustle and earlier this week thousands of tickets were still available. Promoters insist the gate will still be eight-figures, but make no mistake: Mayweather’s popularity following an uninspired win over Manny Pacquiao has taken a hit.
• The story of the week was an SBNation piece written by noted author Thomas Hauser that, among other things, accused Mayweather of having a questionable relationship with the United States Anti-Doping Agency (USADA), which has administered his enhanced drug testing for all of his fights since 2009. I’ll have more to say on this next week, but it’s safe to say the accusations are troubling, less about Mayweather–though the IV he took the day before the Pacquiao fight demands a more detailed explanation–than the USADA. The drug testing agency cannot afford to be seen as offering preferential treatment to an athlete; any credibility that agency has would evaporate.

8:33 PT: Here comes Floyd Mayweather. Mixture of cheers and boos from the crowd. Not much of a roar either way.
8:31 PT: Here comes Andre Berto. Once, Berto was considered a strong candidate to face Mayweather. From 2008-2010, Berto was one of the biggest stars in the welterweight division. But he was exposed against better competition and has since drifted to the fringes of the 147-pound ranks. Deserved or not, he gets the biggest shot of his career now.
8:29 PT: Crowd has filled in, though there are still plenty of empty seats in the building. Mayweather closed at around a 20-1 favorite, and few Vegas gambling experts expect this to be anything more than a Mayweather whitewash.
8:17 PT: A few highlights from the undercard:
Jonathan Oquendo pulled off a mild upset, outpointing Jhonny Gonzalez in a decent super featherweight scrap.
Super middleweight champion Badou Jack won a narrow split decision over former title challenger George Groves in another solid fight. This was a surprise, too; George entered the fight with a far more impressive resume–most notably two tough fights with former 168-pound star Carl Froch–while Jack was considered more of a journeyman who plucked a title from Anthony Dirrell earlier this year.
Jack was solid, dropping Groves with a right hand to the side of the head in the first round and wearing him down with a strong body attack. Of the 127 power punches Jack landed, 52 were to the body; though he was out-punched by Groves (721-506) Jack landed at a far more accurate clip (42% to 21%), according to CompuBox. One of the questions about Groves, 27, coming in was if the two wars with Froch took too much out of him. It was pretty clear they did.
After the fight, Jack called out Julio Cesar Chavez Jr. (who has shown no ability to make 168-pounds) and Lucian Bute (who is shell of his former self). There was no mention of Andre Ward, the undisputed kingpin of the super middleweight division and, frankly, the only fighter a world champion should be interested in fighting.
In the co-main event, Orlando Salido and Roman Martinez battled to a draw in a rematch of a competitive fight last April. The first fight between the super featherweights was an entertaining slugfest, and the rematch was no different, with Salido and Martinez fighting in a phone booth for 12 rounds. Martinez fought well but it was Salido, with slashing body shots and relentless pressure controlling the pace of the fight. SI.com scored the fight 115-113 for Salido, who I thought won a tough but comfortable decision. Both fighters expressed interest in a third fight, and it seems likely Showtime or PBC will put up the money to make it.
