Mandaue City, Philippines native Mercito "No Mercy" Gesta is looking to leave no room for error heading into his Dec. 8 challenge of IBF lightweight champion Miguel Vazquez.

Having ventured from his adopted hometown of San Diego, California, Gesta currently finds himself in the mountains of Big Bear, as he has staged his latest camp out of Abel Sanchez’s Summit Gym.

On Monday afternoon, Gesta could be found sparring eleven rounds, going two with his younger brother Anecito “Mockz” Gesta Jr., seven with talented junior lightweight prospect Joel Diaz Jr. (11-0, 10 KO’s), and two with former national amateur champion Aaron Garcia (10-3-2, 2 KO’s).

It was the work with Diaz that stood out the most for the 25-year old Gesta, as the two took turns picking their spots and landing cracking shots on one another. While neither man ever truly buckled, it was easy to spot just how crisp and thudding their blows were.

While Gesta had success with sharp counter shots, Diaz’s all-out aggression at the start of the fourth round resulted in several memorable exchanges.

Gesta-Vazquez takes place inside of the MGM Grand in Las Vegas on the Manny Pacquiao-Juan Manuel Marquez IV televised pay per view undercard and judging by his work today, “No Mercy” will be in prime shape come fight night.
