After the first three fights between Manny Pacquiao and Juan Manuel Marquez went the distance, these competitors are poised for a knockout.
This rivalry has been one of the best in boxing over the past couple of decades. Pacquiao has won two of the three bouts, with the other being a draw. However, each finish was controversial, as the scoring was so close that it was tough to decide who won.
Both fighters enter the fourth installment of this matchup with the intention to add to their legacies. A knockout win would go a long way towards solidifying the perception from fans around the world.
While it would be a tough maneuver for either fighter, here is a breakdown of the knockout potential for the two sides.
Juan Manuel Marquez
Of the two boxers, Marquez will be the one that is more desperate for a knockout. He has not had any help from the scorers in these bouts, so it will be in his best interest to end it himself.
In addition, he is now 39 years old and does not have the stamina that he once had. Ending this match would only make things easier on his tired body.
The veteran needs to utilize his counter-punching skill to get to Pacquiao when he unguarded. This will help overcome his opponent's speed.
He also must get better at landing his power punches. In the most recent fight against the Pac-man, he only landed 39 percent of this shots, compared to the 43 percent by his opponent (via Boxingscene.com).
Marquez still has a knack for the knockout after a long career, finishing four of his last eight matches early. If he can land some good punches in the upcoming fight, he has a chance to add to that list and pull the upset.
Chance of knockout: 15 percent
Although he has 38 knockouts in his storied career, Pacquiao has not finished a match this way in over three years.
He defeated Miguel Cotto by technical knockout in the 12th round in 2009, but since then has needed the scorers to declare the winner.
Pacquiao still has incredible speed in the ring and can throw more punches than almost anyone else he faces. However, he does not get as much power behind those hits as he once did, and they are not causing as much damage.
To make matters worse, his opponent has not been knocked out in his 20-year career. While he has gone to the mat a few times, it is almost impossible to keep him down.
The southpaw still has great skills and has the ability to come away with a win, but a knockout in this bout seems unlikely.
Chance of knockout: five percent
These fighters know each other very well and they know exactly how to defend every move.
The bout will come down to landing punches and who can do the most damage with those hits.
This should be a very close battle, and there is very little chance that either fighter is able to end the match early. This means that the judges better be paying close attention because it will be up to them to decide a winner.
