Due time constraints, again, we've been limited in what we can o for November 23rd's "On this Day" with only 2 bouts getting a mention.
In 1997 the under-rated Filipino star Gerry Penalosa made the second defense of his WBC Super Flyweight world title as he over-came the previously unbeaten South Korean Young-Joo Cho with a 10 round KO. This bout was Penalosa's first in Korea ans followed recent bouts in Japan, where he won the title, the Philippines, where he defended the belt, and the US where he won a non-title bout. For Cho this would be final bout and his sole world title contest. Subsequent to this contest Penalosa would lose the belt to In-Joo Cho before later claiming a Bantamweight title and carving out a career as one of the most technically proficient fighters on the planet.
More recently, in 2000, Kozo Ishii came up short against Yober Ortega in a bout for the WBA Super Bantamweight title. This bout came just over a year after Ishii's contest with Nestor Garza for the full WBA title though ended in the same fashion with Ishii being stopped in the championship rounds.
