Mayweather vs. Berto Weigh-In: Results and Twitter Reaction for Pre-Fight Event

For possibly the final time in his storied career, Floyd Mayweather Jr. took the stage in Las Vegas on Friday to weigh in for his anticipated matchup with Andre Berto.

The weigh-in for Saturday's welterweight bout saw Mayweather come in at 146 pounds, while Berto tipped the scales at 145 pounds.

After the two men stepped off the scale, the customary staredown took place, albeit without incident, per Showtime Sports:

Here's the full tale of the tape on the eve of the epic confrontation:

Mayweather	Stat	Berto
38	Age	32
5'8"	Height	5'6"
72"	Reach	68.5"
146 lbs	Weight	145 lbs
48-0 (26 KO)	Record	30-3 (23 KO)

One of the big stories leading up to the fight focuses on Mayweather's choice of Berto as an opponent. While no other boxer could come close to drumming up the sort of interest from May's bout with Manny Pacquiao, Berto has not fared well recently, with a 3-3 record over his last six fights. 

ESPN.com's Darren Rovell reported on Tuesday that over 2,100 seats were still available through Ticketmaster and that resale sites like StubHub were seeing less activity than normal. 

The weigh-in was another reminder that the enthusiasm for this bout isn't there, as Joe Castagnino tweeted out a picture of many empty seats:

Even so, Mayweather didn't seem to be losing any sleep over the vacant chairs based on his grin while walking into the arena, per Showtime Sports:

Mayweather has maintained since defeating Pacquiao in May that Saturday will be his final fight. He emphasized that point again in an interview with David Mayo of MLive.com:

"

There's really nothing else to accomplish. ... No one is in my shoes. My health is more important. Anything can happen. I'm not really worried about losing but I want to have a sharp mind. You can make a lot of money but you still want to be able to talk, walk and have a sharp mind.

"

The key point in that statement comes at the beginning, as Mayweather said he has nothing left to accomplish. It's true, certainly, that the bout with Pacquiao was the defining moment for him and the sport. Nothing will top that in terms of buzz and fan anticipation.

Mayweather echoed that sentiment to Jim Gray after weighing in, noting Berto moved into a spot to fight him because he's already taken down everyone else:

Boxing doesn't always see its fighters retire while they are still at the top of their games. Mayweather may be telling the truth about this being his final match, which would make this one of the defining events of 2015. 

All the answers will come Saturday night as Mayweather looks to improve his record to 49-0. It would be one of the biggest upsets in boxing history if he loses, but there was a major upset in tennis Friday when Serena Williams lost in the U.S. Open semifinals.

That should provide a lesson to anyone who thinks that sports follow any semblance of logic. Berto will be in the best shape of his life because this is his moment to prove all of the doubters wrong. Mayweather doesn't take any fight lightly, so expect fireworks to fly in about 24 hours.
