How the Fight Unfolded
Early Rounds
The opening round contained an early moment of confusion when Vargas appeared to drop Walsh with a right-hand shot to the chest. Referee Harvey Dock ruled the sequence a slip rather than a knockdown.
Walsh quickly resumed his pressure.
In the second and third rounds, Walsh increasingly targeted the body and looked to work his left hand through Vargas’ guard. Vargas responded with measured combinations and one-two punches.
Through the first five rounds, CompuBox had Walsh landing 74 of 339 punches, compared with 64 of 180 for Vargas.
Middle Rounds
Rounds four through seven contained some of Vargas’ strongest moments.
The American boxer was able to land clean combinations and use his accuracy to make Walsh work for his opportunities. Vargas’ power punching was particularly effective during portions of this stretch.
Walsh, however, continued to throw more frequently.
Rather than allowing the fight to become a low-volume counterpunching contest, Walsh kept creating exchanges and maintained a steady pace.
Championship Rounds
The eighth and ninth rounds became particularly important.
Walsh increased his activity and threw more than 100 punches in each of those rounds. Vargas’ output began to decline as the fight moved beyond the seventh round.
In the 10th round, Walsh finished strongly and landed a left hook after Vargas moved forward.
The final CompuBox total showed Walsh ahead 182-159 in punches landed.

The fight was interesting because both men are southpaws, but their approaches were different.
Callum Walsh

- High punch volume

- Sustained activity late in the fight
His biggest statistical advantage was volume. He threw 876 total punches compared with 451 from Vargas.

Fernando Vargas Jr.
Vargas showed a more selective approach.
His overall punch volume was much lower, but his accuracy numbers were better. He landed 159 of 451 total punches and connected on 46.3% of his power punches.
His best stretches came when he was able to sit down on combinations and counter Walsh’s pressure.
The problem for Vargas was maintaining that effectiveness for the full 10 rounds while dealing with Walsh’s activity.
