LAS VEGAS (AP) -- Floyd Mayweather Jr. has taken his quest for a fight with Manny Pacquiao to Twitter.
The unbeaten Mayweather called out the Filipino superstar on Tuesday, daring Pacquiao to meet him May 5 in Las Vegas.
Mayweather and Pacquiao are boxing's top two stars, and they have circled each other warily for more than two years. Both have said they're eager to fight, yet neither has agreed to a deal for what's likely to be the most lucrative bout in boxing history.
Mayweather has stepped up his campaign since Pacquiao's narrow win over Juan Manuel Marquez last November.
Mayweather is available for a fight in May at the MGM Grand Garden after a Las Vegas judge agreed last week to postpone his jail sentence in a domestic violence case until June.
