The much-anticipated bout between Floyd Mayweather Jr. and Manny Pacquiao is all but set for March 13, a source told Yahoo! Sports.

Mayweather has agreed to terms and promoter Bob Arum is making a trip to Manila, Philippines, to finalize a deal with Pacquiao, the source said.

Las Vegas, Dallas and New Orleans are the front-runners to host the bout, which is expected to become the highest-grossing boxing match in the sport’s history.

Pacquiao is the top pound-for-pound fighter in nearly every major ranking, including Yahoo! Sports. Mayweather is No. 2 in most rankings and was No. 1 in nearly all of the polls before he briefly retired in June 2008.

Pacquiao is coming off a 12th-round stoppage of Miguel Cotto on Nov. 14 at the MGM Grand Garden Arena in Las Vegas, a bout in which he won the World Boxing Organization welterweight championship and erased fears that he is not a legitimate welterweight.

Cotto was a legitimate welterweight in his prime and Pacquiao dominated, knocking him down twice and cruising to the one-sided victory.

Mayweather routed Juan Manuel Marquez, who had previously been ranked No. 2 in the Yahoo! Sports poll, in a Sept. 19 fight at the MGM Grand.

The public demand for the fight has been enormous, putting pressure on Arum and Golden Boy Promotions CEO Richard Schaefer, who represents Mayweather, to get a deal done.
