Alvarez had come into this one on the back of a shock win of his own, when he stopped the once touted Jonathan "Bomba" Gonzalez in Puerto Rico. That win had followed a solid performance against Juan Francisco Estrada, albeit in a decision loss to "Gallo" Estrada. Those performances had seen some suggest that Alvarez was likely to become a staple on the fringes of world class and had helped him earn top 10 world rankings with 2 of the 4 major title bodies.
Last night however the the youngster was dropped within a minute and finished off soon afterwards with the referee needing to save the 26 year old Filipino.
Coming into the bout Cartagen had been stopped in 2 of his previous 5 and was 2-3, including stoppages to Emmanuel Rodriguez and Timur Shailezov. His career was floundering however this win could potentially see him lifted into the fringes of the world rankings at Flyweight, whilst hammering yet another blow into Filipino boxing which appears to be going through a minor slump at the moment.
