Undefeated knockout artist Roderek Bautista puts his immaculate record on the line against Arvin John Sampaga when Manny Pacquiao Presents: Blow-By-Blow returns with another fistic fireworks Sunday at the Ramon Magsaysay Covered Court in Quezon City.

Set for 10 rounds and with the Philippine Boxing Federation light-flyweight throne on the line, Bautista will have his hands full in the slugfest that is being presented by Ginebra San Miguel and shown every Sunday at 8:30 p.m. on One Sports channel.

Fighting out of Moreno Boxing Tam of Digos, Davao del Sur, Bautista parades a 6-0 slate with five knockouts. Sampaga, representing Sampaga Boxing Stable of Masbate, packs an 8-1-1 ledger with three stoppages.

Pacquiao, Blow-By-Blow’s premier product, revived the show two years ago as a promise to Philippine boxing of his commitment to lend a hand.

“As the country’s only regular boxing program on television, Blow-By-Blow remains committed to its mission of lending a hand to Philippine boxing,” said Pacquiao, who credits Blow-By-Blow as a prime mover in his rise to superstardom.

The last two years, Blow-By-Blow has staged cards not just in Metro Manila but in the provinces as well.

It has made stops in Ilocos Sur, Cavite, General Santos City, Surigao del Sur and Iloilo.
