Bautista realized that the first round was too slow that he had to catch up with the aggressive Mexican challenger Eden "Anestesista" Marquez.
Starting slow, Bautista threw only two punches in the first round.
So he made up in the second round and must have overdone it that he sent Marquez on the canvas by a technical knockout .
The dizzy Mexican stood up at the eighth count only to suffer another knockdown at Bautista's release of a hard right hook to the head.
This forced referee Bruce McTavish to stop the bout just over a minute remaining in the second round.
Before Marquez, Bautista had already defeated two Mexican warriors as he defended his regional belt, wining against Antonio Meza via unanimous decision in December 8 last year and knocked out Genaro Camargo in the second round of their battle last April 6.
