The Cuban settled the lawsuit against Flores in Los Angeles with a devastating blow.
Cuban heavyweights Luis Ortiz Y Frank Sanchez two wins were scored this Saturday by knockouts on a card developed at the Microsoft Theater in Los Angeles, California.
King Kong Ortiz (32-2, 27 KOs) impressed on his return to the ring by knocking out Alexander The Great Flores (18-3-1, 16 KOs) in the first round of a 10-round bout.
Returning to the ring after a loss to the then heavyweight champion Deontay Wilder Last November, Ortiz showed that despite his 41 years he is still among the best heavyweights today.
The Cuban left-hander landed a series of punches and ended the lawsuit with a left foot, forcing Flores to retire early.
Flores doubled over after a blow to the ribs, giving Ortiz the victory to the 45 seconds of the first round.
On the other hand, his compatriot on the rise in the heavy category, The Cuban Flash Sánchez (16-0, 12 KOs), remained undefeated with a fourth-round knockout over Brian Howard (15-4, 12 KOs), knocking him down three times on his way to victory.
Sánchez was stalking his opponent and forcing the action effectively from the start. At the end of the third round, Sanchez broke through with a forehand that surprised Howard, before a left hook and a straight right sent him to the mat.
In other heavyweight fights, the undefeated Michael Coffie (11-0, 8 KOs) scored a TKO win over veteran Joey Abell (35-11, 33 KOs) in the second round.
Coffie landed with a left hook to the body that ended the fight early in the second round.
In the opening fight, the Puerto Rican Olympian Carlos Negron (22-3, 18 KOs) beat the Mexican Rafael Rios (11-3, 8 KOs) at 2:33 in the second round.
