Highly rated super middleweight contender Gilberto "Zurdo" Ramirez (32-0) kept his perfect record intact with an unanimous victory over former prospect Derek Edwards (27-5-1) in the main event of the latest installment of Metro PCS Friday Night Knockout on truTV. The final tallies were 100-90 on all three scorecards.

The 6'3" Ramirez put on a dominating performance after receiving criticism following his January workman like decision victory over Maxim Vlasovib Denver, Colorado.

Zurdo, who is ranked in the top three of all four major sanctioning bodies, started out fast, using his reach advantage to attack from the outside.

The 24-year-old was very effective using his reach advantage throughout the fight. He staggered Edwards on multiple occasions at the end of the third round bringing the crowd to it's feet.

Ramirez's dominance was just starting as he landed several hard shots to end the fourth round. Both fighters traded wicked shots at the of the round but Edwards clearly got the worst of it as Ramirez landed big punch after big punch as he tried to end the fight before the bell rang.

Edwards recovered between rounds and was able to get out of the fifth despite Ramirez's assault. Edward's trainer Jeff Mayweather pleaded with him to close the distance but the 35-year-old was never able to do it consistently.

The referee nearly stopped the fight in the eighth as Edwards appeared out on his feet but the resilient Edwards made it out of the end of the round.

Ramirez tried to close the show in the    tenth and final round but had to settle for a shut out decision victory. With the victory the Mazatlan, Sinaloa, Mexico native inched closer to a title shot. 

Top Rank CEO Bob Arum recently stated that Ramirez would likely return on a Top Rank pay-per-view card being planned for September 26th in Mexico.  

In the latest edition of truTv's Friday Night KO series, Diego Magdaleno (28-1) moved closer to a title shot by defeating Jose "Chelo" Gonzalez (24-2) via 7th round TKO in a bizarre fight that was light on action.

The action started out slow as both fighters felt each other out in the first round. The action was so slow that referee Luis Pabón motioned to both fighters to get busy early in the second.

Magdaleno tried to pick it up in the third as he was the aggressor and Gonzalez was content to counterpunch. A straight right hand by the Puerto Rican wobbled Magdaleno in the fifth to temporarily slow his momentum. 

The Las Vegan Magdaleno picked up the pace in the sixth, landing several big left hands. He did however suffer a cut that bled into his eye. The cut was ruled to be caused by a punch.

Magdaleno landed a big shot early in the seventh that got Gonzalez's attention. Gonzalez would go down seconds later but it would be correctly ruled a slip. He went down a second time from what was ruled a very questionable low blow and Gonzalez said that he couldn't continue after his allotted five minutes to recover.

Chelo, who also quit in his title fight against Ricky Burns that he was winning, suffered his second career loss.

Magdaleno is now the mandatory challenger to the winner of the Terry Flanagan-Jose Zepeda bout for the vacant WBO lightweight title that Terence Crawford vacated when he moved up to the super lightweight division.
