He beat Julio Diaz decisively last night.</p> Juan uses his exceptional hand speed to throw combination after combination and make his opponents give up.</p> It appears his next fight will be against Manny Pacquiao, who isn't a lightweight and will have a tough time against Diaz.</p> If Juan fights David Diaz, it will be a true unification fight. The winner would hold all four lightweight titles.</p> Joel Casamayor is also out there somewhere, so the lightweight division should stay interesting for a while.</p>
