Argentine champion Fernando Martinez believes he has all the bases covered in preparation for the first defense of his International Boxing Federation super-flyweight crown against Jerwin Ancajas on Saturday night in Carson, California.

"I have a Plan A and a Plan B. We'll be ready for absolutely anything. It's going to be another great show for fans all over the world. Everyone is going to be happy that they tuned into this fight," Martinez said during a presser held yesterday.

Martinez had beaten Ancajas last February on points, banking heavily on his non-stop punching to mess up the Filipino southpaw's gameplan.

But that's all in the past now Ancajas said, stressing that the buildup for the rematch enabled him to make the right adjustments.

"I was not in as good of shape in our last fight. I fought toe-to-toe because my legs were cramping in the fight. Now we've prepared for what he does in the ring and we'll be ready to reclaim our belt," he said.

Ancajas spent the first half of training camp in Magallanes, Cavite, before relocating to Las Vegas four weeks ago with lead trainer Joven Jimenez.

Oddsmakers have installed Martinez as -230 favorite ($230 wins $100) while Ancajas as +175 ($100 wins $175).

Before giving up the IBF 115-lb belt, Anacjas made nine defenses, fighting in Macau, Belfast in Northern Ireland, Brisbane in Australia, Corpus Christi (Texas), Stockton, Fresno and Oakland (California), Uncasville (Connecticut) and Puebla in Mexico.
