Carlos Molina is hard on himself.

The Mexican fighter who trains out of Chicago gave himself a barely passing grade despite an impressive unanimous decision over Damian Frias in the main event of Friday night's boxing card at the Buffalo Run Casino.

“I know I can always do better,” said Molina, who is the IBF's sixth-ranked junior middleweight. “I am always hard on myself, I would give myself a D. We had a good gameplan. I wanted the knockout. I wasn't happy with that, but its all right. As long as I didn't get a loss or a disqualification, right?”

Molina (20-5-2, 6 KOs) was coming off a bitter loss by disqualification in the 10th round of his March WBC Continental Americas light middleweight title fight with James Kirkland in Houston.

He left no doubt here Friday night.

After a slow start, he began to dominate, using good combinations to impress the judges.

Molina was impressed with the resilience of Frias (19-5-1, 10 KOs).

“I knew he was going to come here to fight,” Molina said. “I was expecting a tough fight from him.”

Judges David Sutherland, Henry Ellick and Chris Ritter all scored the fight 100-90 in favor of Molina.

The fight, the main event for ESPN2's “Friday Night Fights” season finale, had been moved up from the co-feature after the Don George-Adonis Stevenson bout was scrapped due to an injury to Stevenson.

Molina said this wasn't the first time he has been the main event on “FNF.”

“ESPN has been real good for me,” Molina said. “Without them, I don't know if we could survive. A lot of people get their first opportunities on ESPN.”

He's not sure what is next, but “I want to get back out there as quick as possible. I came out healthy and not hurt, so as soon as possible.”

In the co-feature, Don George (23-2-1, 20 Kos) won by technical knockout over Dionisio Miranda at the end of the sixth round of their super middleweight bout.

The career of Viliar Quiñones got a boost when he posted a unanimous decision over Eddie Tigs in a four-round super middleweight fight that got air time on ESPN.

The win was the fifth straight without a loss for Quiñones, who was born in Cuba but now trains in Miami, Fla.

Junior lightweight Tyler Asseltine of Ottawa, Ontario, improved to 10-0 with a unanimous decision over Robert Bonilla of Ciudad Sandino, Nicaragua.

In the other fights:

Shi-wone Gortman of Del City went to 3-0 as a pro with a unanimous decision over Octavio Gray of Oklahoma City in lightweight action. Gray now is winless in three fights.

Willie Gilbert of Oklahoma City and Tulsan Chris Barnes battled to a draw in a middleweight battle. It was Gilbert's pro debut and just the second for Barnes.
