Mega bout packing big punch

Record-shattering revenue totals for Manny Pacquiao's May 2 showdown with unbeaten Floyd Mayweather could surpass $400 million, promoter Bob Arum told ESPN in a report on the sports network's website.

The welterweight title unification fight in Las Vegas will generate $74 million from just more than 15,000 tickets at MGM Grand Garden Arena, Pacquiao promoter Arum told ESPN on Monday, flattening the old mark of just more than $20 million for Mayweather's 2013 fight with Canelo Alvarez.

Promoters first aimed for $40 million, then boosted the ticket prices from $1,000 to $1,500 at the low end and $5,000 to $7,500 for the best seats due to huge demand, Arum said.
