Floyd Mayweather Jr. retained his top spot in the Yahoo! Sports boxing rankings for June, though the margin over runner-up Manny Pacquiao tightened.

For the first time in the nearly three-year history of the poll, all members of the panel submitted votes. In May, when Mayweather took over the top spot from Pacquiao after routing Shane Mosley, 33 members of the 38 on the panel submitted ballots.

Two writers were dropped after May's balloting due to a consistent failure to participate. In their place, four voters were added, bringing the total to 40: Nick Giongco of the Manila Bulletin, Chino Trinidad of GMA Television in the Philippines, Gareth A. Davies of the London Telegraph and Tris Dixon, editor of Boxing News in London.

Pacquiao fans cried bias when their man dropped from No. 1 to No. 2 in the poll. That prompted me to this month keep track of where the votes were coming from for each guy.

Mayweather received 22 of the 40 first-place votes cast. He received 18 votes from reporters representing outlets in the U.S. Pacquiao received 12 first-place votes from U.S. outlets.

Each fighter got one first-place vote from Puerto Rico. Pacquiao received both first-place votes from England and Mayweather got the only first-place vote from Scotland.

Pacquiao got the first-place vote in Germany, Mayweather took the first-place vote in both Thailand and Australia. Pacquiao got both first-place votes from the Philippines.

I voted for Mayweather first, though it was a tough call. But defense wins championships in just about every sport and I think Mayweather's nearly impregnable defense is what gets him the slightest of edges.

It's clearly open to debate and I'm the first to concede that there is no obvious choice.

For the record, my votes this month were, in order, Mayweather, Pacquiao, Paul Williams, Timothy Bradley, Andre Ward, Chad Dawson, Sergio Martinez, Chris John, Juan Manuel Lopez and Fernando Montiel.

With that, let's take a look at the updated rankings:
