Rosario by KO. I like Chico, but he was there to be hit. At 135, Cassamayor and Castillo had him down (and sometimes out) on multiple occasions. Rosario is better, and hits way harder than both those men.
Sorry to say. Edwin was a better fighter and this would look like when Edwin fought that guy in Sacremento whose name escapes me. He was the 140 pound titlist and Edwin knocked him out in 3 rounds. Edwin would stop Corrales rather easily. This is a good style for him. A guy who cannot take a great punch who Edwin would walk through.
Diego like to trade. And absorb numerous power punchers with his memorable fights with Castillo. This would be a mistake with heavy hands of Rosario. Rosario by stoppage in 4 rds.
Yes Garza. Get a little older and you forget names for some reason.. Similar fight. Edwin would beat Corrales rather easily.
I'd be pretty confident in Rosario KO inside 6. While Corrales could punch, Rosario could really punch. Corrales is just too willing to slug.
Rosario cracked the "coconut head" Bramble with ease, and Bramble had a beard & a defense of sorts...much more so than Corrales. Edwin Rosario ko's...as in knocks out...Diego Corrales within 3 rounds.
