Junior bantamweight David Cuellar remained unbeaten Sunday night, dropping Ricardo Blandon twice en route to a knockout win in round 6 at the Centro de Convenciones in Cancun, Mexico.

Cuellar, who resides in Queretaro, Mexico, improves to 21-0, 14 knockouts. 

The victory over Blandon took place less than four months after Cuellar knocked out former world WBC strawweight titleholder Moises Fuentes. 

Sunday marked a stay-busy for Cuellar, but Blandon came to fight and was game early on. Both exchanged combinations in the center of the ring, but Cuellar landed the more-effective punches. 

Less than a minute into round 5, a right hand dropped Blandon to the canvas. Blandon beat the count and was able to make it out of the round, but looked worse for wear from the number of punches he took during the round. Cuellar ended matters in round 6, dropping Blandon with a left hook to the body. Blandon winced in pain as he was counted out.

Blandon (15-5, 9 KOs), who resides in Managua, Nicaragua, has now lost three of his last four bouts. 

In the co-feature, junior featherweight Christopher Lopez of Guadalajara, Mexico defeated Dixon Flores by unanimous decision. 

Scores were 99-91, 99-91, and 100-90 for Lopez, who improves to 15-0-1, 10 KOs.

Flores came to fight and was game in each round, willing to stand in the pocket and receive punches to land his. The tactic worked at times, but Lopez landed at will to the head and body against Flores.  

The 27-year-old Flores, who resides in Juigalpa, Nicaragua, drops to 17-9-3, 6 KOs. 

In an all-out brawl between two junior lightweights from Mexico, Rosario Sanchez (17-0, 10 KOs) of Los Mochis defeated Francisco Lucero by majority decision. 

One judge scored the 76-76, while the other two judges scored the bout 77-75 and 78-74 for Sanchez. 

Both fighters threw a high-volume of punches at one another, bringing about solid exchanges between the two fighters. Lucero did well in spots, but Sanchez was able to stay one step ahead, connecting with several combinations to Lucero’s head and body.

Lucero, who resides in Hermosillo, drops to 10-4-4, 7 KOs.

Junior middleweight Brandon Perez improved to 7-1-1, 2 KOs by defeating Oziel Santoyo by unanimous decision. Scores were 76-74, 76-74, and 78-72 for Perez. Santoyo drops to 13-2-1, 8 KOs.
