A
southpaw with good power, Guerrero turned pro at
seventeen in 2005. He went 9-1-1 over the next
three years, before winning his first title, the
WBC Continental Americas Bantamweight, in 2008
with a twelve-round decision over 28-3 Juan
Alberto Rosas, who later went on to also become
IBF world champion.
In 2010
Gueerero challenged for the WBA and WBC world
Super Flyweight titles, losing on points to
Armenian Vic Darchinyan in California, but just
four months later he was back in the picture for
another shot when he beat Filipino Federico
Catubay in an IBF eliminator.
In
November of 2010 he lost a split decision in
another eliminator to Raul Martinez, but was
found deserving of a rematch which ended up
being for the vacant IBF world championship.

This time,
in October 2011, he beat Martinez by technical
decision after six rounds, and was the new IBF
world champion.
He lost the
world title in his first defense, to Juan Carlos
Sanchez Jr., but earned another crack in 2013
which he lost on points to Daiki Kameda in Japan.
Continuing
to fight at the world class level, Guerrero moved
up the weights and won several regional titles
against good opposition. When he received the
opportunity to fight Noel Echevarria (18-7) for
the vacant UBO world Lightweight title in the
summer of 2021, he jumped at the chance.
It was a
good, competitive fight at the World Congress
Center in Atlanta, Georgia, and, as always,
Guerrero gave everything he had. Unfortunately for
him, Echevarria was just a bit sharper and
fresher, winning by close (114-112, 114-112,
116-111), but deserved decision.
At 34,
Guerrero is still plugging along and fighting
whoever is willing to take him on. More of a
gate-keeper than a contender these days, his
current record stands at 26-15-2 (16).
