Bantamweight Ivan Morales sent out a message on his Twitter account this past Friday afternoon that exuded confidence (translated to “This is for my friend who bet it all on 5 red (5th round KO)”). Or maybe it was overconfidence.

Whatever it was, he may now regret doing so.

Little-known Edgar Jimenez scored an upset majority decision win over Morales late Friday night in Playa Del Carmen (near Cancun), Mexico.

With the win, Jimenez improves to 20-11-2, 14 knockouts, while Morales falls to 28-1, 16 KOs.

Jimenez may not have the best won-loss record, which may have prompted Morales to tweet out on his account that he did not see the fight lasting past the fifth round. He could not have been further from his prediction as Jimenez, who made his pro debut at the age of 15, not only came to fight but came to win.

Both fighters had their moments in the first half of the fight. Jimenez pressed the action, attempting to walk Morales down and mixing in his attack from the body to the head. Morales, the younger brother of Erik Morales, was at his best when he initiated exchanges.

The fight was more compelling in the second half of the fight. Morales seemed to stun Jimenez with a right uppercut but also slowed down considerably in the final two rounds. Jimenez seemed to get a second wind, pressing the attack and scoring at will to Morales’ head, getting the fan support in the process.

One ringside judge scored the bout 95-95, while the other two judges scored the bout 97-93 for Jimenez.

Medina quits, Perez wins by TKO

In the main event of the Golden Boy Promotions/Cancun Boxing card, light flyweight Ricardo Perez survived a second round knockdown to force Noe Medina to quit in the ninth.

With the win, Perez goes to 9-2, 8 KOs, while Medina drops to 5-4, 1 KO.

After a competitive opening round, Medina dropped Perez with a clubbing counter right to the head with less than a minute remaining in the second round. Perez was able to get up and make it out of the round.

Perez began to swing momentum his way over the next round or so, walking the taller Medina down, backing him up against the ropes and into a corner. Perez was at his best getting on the inside of Medina’s guard, repeatedly tagging him with lefts and rights.

As the bout progressed, Medina’s punch output dropped, allowing Perez to increase his aggression. Medina complained he hurt his left hand in the seventh round, further complicating matters. He convinced his corner to allow him to fight on but he was getting hit repeatedly in the ninth round, prompting his corner to throw in the towel at 1:01.

The scheduled 10 round bout between lightweight contender Sharif Bogere and Daniel Ruiz abruptly ended after the second round.

Bogere remains at 27-1, 19 KOs, while Ruiz stays at 33-8-2, 23 KOs.

Bogere looked as though he landed a punch that opened a cut on Ruiz’s face, although Ruiz complained that an elbow opened the cut. Ruiz left the ring at the conclusion of the second round, prompting referee Celestino Castro to declare the bout a no-contest since the bout did not complete four rounds and it was inconclusive whether the cut was opened by a punch or an elbow.
