IBF mini-flyweight champion Pedro Taduran on February 27, 2021 at the Bula Gym in
General Santos, Philippines. The bout was initially expected to take place in January, but had to be postponed due to the ongoing

In a fight which saw Cuarto box at range while the defending champion took a more aggressive role, Cuarto defeated Taduran over twelve rounds via UD, capturing his first world title with all three judges scoring the bout 115–113. Cuatro faced Taduran in an immediate rematch in his first IBF mini flyweight title defense. The bout was initially scheduled to take place at the City Gymnasium in
Digos,
Philippines on January 29, 2022, but was eventually postponed for February 6. Cuatro retained the title by a seventh-round technical decision. The bout was stopped due to a cut on Taduran's forehead, which was caused by an accidental clash of heads in the sixth round, after which Cuatro was awarded the majority decision. Two of the judges scored the fight 65–64 and 66–64 in his favor, while the third judge scored it as an even 65–65 draw. Cuatro knocked Tadruan down in both the second and sixth round and was deducted a point in the third round for an intentional headbutt.
