Petalcorin's promoter Peter Maniatis is said to be in talks with a trio of possible opponents for the fight.
Of those possible opponents the preferred option is apparently Panama's Walter Tello (20-7, 8). Tello, ranked #14 by the WBA at Minimumweight and is a light puncher. Although there are no major wins on his record he has mixed with decent company and fought against Alberto Rossel last year, Rossel of course was promoted to WBA regular champion a few weeks ago. Perhaps notably for Filipino Tello does hold a win over Jorle Estrada who fought Merlito Sabillo last year.
An alternative opponent would be Mexico's Saul Juarez (20-3, 11) who is the #6 ranked WBA Light Flyweight. Although not the greatest fighter in the division Juarez does have some very good wins including decisions over Oswaldo Novoa, Luis Ceja and Martin Tecuapetla. Juarez would be a very tough opponent for Petalcorin and probably the hardest opponent that Petalcorin would have faced thus far in his career.
The third possible opponent is the hard hitting Gilberto Parra (18-2, 16). Parra, ranked #8 at Light Flyweight by the WBA, is another Mexican foe and one who appears to have serious power. Parra's wins so far have been the least impressive but with 16 T/KO's in 20 fights he is a very heavy handed fighter and boasts an 80% stoppage record. This guy is mystery due to his level of competition but with that sort of fire power he could give Petalcorin some real difficulties.
We are awaiting to see which of these guys does agree to the fight though, from our perspective, Juarez would be the best opponent and would certainly be the one that Petalcorin would likely prefer not to fight.
