Mayol stretched his unbeaten streak to 21-0, including 16 wins via stoppage, after winning by decision over Japanese Takayugi Kurugi in his third defense last April 4 at the Central Gym in Osaka, Japan.
Trejo, on the other hand, compiled a 22-12 win-loss record in his 10-year pro career.
After losing to Ivan Calderon by decision in their WBO minimumweight title bout on September 5, 2003 in Puerto Rico, Trejo racked up six straight wins, including an eighth round stoppage of Oscar Murillo to wrest the NABF diadem on November 22 last year in Mexico.
This as the WBC has approved the forthcoming return bout between Manny Pacquiao and Erik Morales on January 21, 2006 as a final elimination bout, with the winner earning a mandatory shot at the WBC super featherweight title currently held by Marco Antonio Barrera.
Morales lost twice in three fights against Barrera, the last cost the former his WBC jr lightweight throne. Pacquiao, on the other hand, gained phenomenal fame worldwide following his brutal 11th round destruction of Barrera in 2003 in their first and only match so far.
Bautista jumped into international stardom when the Candijay, Bohol hard-puncher pulled off a spectacular third round knockout over Colombian Felix Flores Murillo.
Bautista's triumph sparked a stirring 3-0 sweep by the Filipino fighters over their Latino rivals in last month's "Double Trouble" card at the Staples Center, with Viloria knocking out Ortiz in round one and Manny Pacquiao decking Mexican Hector Velasquez in round six.
Aside from a Colombian, the 19-year-old Bautista had also demolished boxers of different nationalities such as Mexican, South African, Korean, Japanese, Thai, and Indonesian in just his two-year pro career.
