Interesting matchup. Martinez has never really faced a guy like Roldan. Just a bull strong guy w/heavy hands, who would be in trying to maul down Maravilla from the jump. Martinez is talented enough to steer his way through to a close decision, but I wouldnt be a bit surprised if Roldan was just too strong and relentless for him.
Agreed, not a lot to go on. However I'd have to favor Martinez as well because matchups involving bullies against skilled boxers end up with the boxer winning 90% of the time. Exceptions are usually if there's a big difference in age or size.
