Pacquiao vs Marquez Results: Timothy Bradley Shows He Is Best Light Welterweight

Timothy Bradley knocked out Joel Casamayor in the eighth round of their fight for the WBO Light Welterweight Championship on the Manny Pacquiao vs. Juan Manuel Marquez undercard.

Bradley illustrated that he's the division's best boxer with a convincing victory. Casamayor tried to keep it close with a defensive, slow-paced approach that didn't endear him to the fans, but it wasn't enough to stop Bradley, who moved to 28-0.

Only Amir Khan could stake a claim that Bradley doesn't belong atop the division. Khan is the unified WBA Super and IBF Light Welterweight Champion while Bradley holds the WBO Light Welterweight title.

It would be interesting if the two could agree on terms for a fight to settle the score once and for all, but it's still unclear whether both sides would be willing to do that considering the loser would be left out in the cold.

However, it would equate to a very strong undercard bout and may even be able to work its way onto Floyd Mayweather's card in early May. The placement alone could help increase the purse size enough to convince both men to agree.

Either way, Bradley has a pretty good case to be considered the best light welterweight.

The only thing he lacks is legitimate knockout power, with just 12 in 28 wins as opposed to Khan's 18 in 26 wins. That said, it isn't necessary to win by KO if you can wear down your opponent to dominate the late-round scorecards.

Bradley has shown great endurance throughout his career, which started in 2004, and Saturday's fight was on the biggest stage yet. Even that couldn't force him to change his game plan, as he slowly but surely destroyed Casamayor.

He'll continue to be favored in every fight unless he goes up against Khan. And in reality, he should be willing to take on that task because it's hard to imagine him ever finding better form than he's in right now. Erik Morales is always another option.

Whoever he fights next, Bradley will have a good chance as long as he fights within his means and doesn't try to do too much early in the bout.
