Filipino boxing star and three-division world champion John Riel “Quadro Alas” Casimero dominated Mexico’s Cesar “Perico” Ramirez en route to a tenth-round knockout win to retain the WBO Interim Bantamweight World Championship, Saturday evening.

The Casimero-Ramirez tussle was the marquee attraction of the Manny Pacquiao Championship Boxing offering at the San Andres Sports Complex in Malate, Manila.

Casimero was simply too much for the Mexican challenger as he outclassed Ramirez and put the former WBC FECOMBOX Champion down on multiple occasions leading up to the tenth-round finish.

The smaller Casimero uncorked a solid left uppercut and followed up with a vicious right hook that landed flush on the jaw, sending Ramirez’s mouthpiece flying before the Mexican dropped to the canvas.

With the win, Casimero extended his winning streak to four straight and now sets up a WBO Bantamweight World Championship unification bout against reigning titleholder Zolani Tete of South Africa.


Filipino Interim WBO Bantamweight world champion John Riel Casimero (24-4, 18 KO’s) and taller Mexican challenger Cesar “Perico” Ramirez (18-3, 11 KO’s) successfully made weight ahead of their title battle this Saturday, August 24, at the San Andres Sports Complex in Malate, Manila.

The battle will air live on ABS CBN S+A channel 23 starting at 7:00 PM.

The challenger from Colonia Los Fresnos in Tepic, Nayarit, easily made 117.6 pounds in his first try.

Casimero, 30, had to go to extra two hours of sweating to make the limit of the bantamweight division, 118 pounds.

According to WBO fight supervisor Leon Panoncillo, the winner of the clash is mandated to battle WBO regular bantamweight world champion Zolani Tete (28-3, 21 KO’s).

“I am going to win. I have dreamed about being a world champion this for too long. This is my golden door and I am walking in,” said the 31 year-old Ramirez, in his second war in a foreign land.

Three years ago Ramirez battled then Ryan Burnett (20-1, 10 KO’s) in Leeds, England, losing by points. This time he is gunning for the gold.


Mexican Cesar Ramirez landed in Manila and immediately dropped by Plaza Mexico, a public square that commemorates the historic Galleon Trade involving Manila and Acapulco that spanned centuries.

Boxing legend and Senator Manny Pacquiao returns to the Philippines on August 24 as he takes a timeout from breaking records inside the ring to promote a world title bout.

‘Pacman’ who delivered a stunning performance against the previously undefeated Keith Thurman in July, is staging the fight under MP Promotions alongside Sean Gibbons.

The welterweight titleholder will host a mouth-watering showdown between two-division king John Riel Casimero and Mexico’s Cesar Ramirez in Manila.

The Filipino won the WBO Interim Bantamweight strap in his most recent fight after inflicting a KO defeat to Ricardo Espinoza. Casimero, a fellow compatriot of Pacquiao, knows a victory will see him become mandatory challenger to WBO titlist Zolani Teti. ‘Quadro Alas’ has won three successive contests since returning to the ring in 2018. He has won IBF world titles at light-flyweight and flyweight, respectively.

The 29-year-old started preparation with eight-weight ruler Pacquiao in LA. He is currently training at the MP Stable in Davao City under Nonoy Neri. Casimero aims to continue his charge on the bantamweight division. He faces a stern test in Ramirez, though, who is ranked inside the top 10 of the WBO rankings. Since tasting defeat to former unified world champion Ryan Burnett, the Mexican is on a six-fight winning streak, with five inside the distance.

The Manny Pacquiao Championship Boxing event will see another intriguing duel at 118lbs as Vincent Astrolabio takes on Kevin Aseniero. The bout is an all-Filipino battle for the WBO Oriental belt in the co-feature of the evening. This is a show not to miss and it all goes down on August 24 at the San Andres Sports Complex in Manila on August 24.


Earlier this week British TV channel Boxnation announced that they would be broadcasting the upcoming WBO “interim” Bantamweight title fight between champion John Riel Casimero (27-4, 18) and Mexican challenger Cesar Ramirez (18-3, 11), live from the Philippines.

The bout is one of the very few Asian shows the channel has picked up, which is disappointing from the “Home of Champions”, but it’s better late than never.

The bout will be Casimero’s first defense of the title he won earlier this year, when he stopped Ricardo Espinoza Franco in the final round of a very close bout, and will see him seeking a 4th straight T/KO win, as he’s rebuilt wonderful from his disappointing 2017 loss to Jonas Sultan. On the other hand this will be Ramirez’s first “world” title bout, and see him hunting a 7th straight win.

​Interestingly both fighters have previously fought in the UK, where Boxnation are based. Ramirez fought against Ryan Burnett in 2016, being dropped in the 8th round before losing a very wide decision to the Northern Irishman. Casimero’s UK bout was also in 2016, when he stopped Charlie Edwards in 10 rounds to retain the IBF Flyweight title. It’s also worth noting that the winner will have a fight with Zolani Tete lined up, someone who is promoted by the UK’s Frank Warren, and that bout could well end up in Britain as well.
