Jason Sosa knows he is fighting in the biggest fight of his young career.

You wouldn't know by the relaxed demeanor he has been in the lead up to the fight.

"I'm taking this as another fight."

Sosa must be very cool, calm, and collected, considering he is fighting one of the more-explosive punchers in boxing today.

Sosa will fight Saturday night against former featherweight world title-holder Nicholas Walters at the Turning Stone Resort and Casino in Verona, N.Y. The 10 round bout will open the HBO 'Boxing After Dark' telecast, beginning at 10:15 pm ET/ 7:15 pm PT.

Based on the opposition Sosa has faced in his career, Walters is not just another opponent. The Jamaica-born fighter won the WBA title as a featherweight and defended the title three times.

Walters lost the title on the scales in his last fight on June 13, weighing in one pound over the featherweight limit.

Sosa (18-1-3, 14 KOs) may be the underdog against the more-experienced Walters, but still likes his chances to come out victorious on Saturday.

"He's an undefeated guy with a nice record," Sosa told Boxingscene.com in a recent phone interview. "He's a good fighter with good power, but that was at 126 (pounds). 130 pounds is a whole different weight division."

"I've seen a couple flaws. He's pretty good overall, but I'm ready to do my thing."

Doing his thing in recent years has culminated in impressive streaks for Sosa. The 27-year-old is unbeaten in his last 17 bouts and has knocked out his 13 opponents in a row.

Some in boxing believe Sosa is a live dog against Walters, considering he has fought at or around 130 pounds throughout his career. Rumor has it that the winner of the Walters-Sosa fight could face Takashi Uchiyama, should the Japanese fighter win on December 31.

"It would be a great win for me (over Walters)," said Sosa, who is co-promoted by Top Rank and Russell Peltz. "A win on Saturday would put me with the top 130-pound fighters."

A win on Saturday would also put his hometown of Camden, N.J. on the map. The city on the other side of the Delaware River from Philadelphia has received negative press due to the high homicide rate and rampant crime that exists in the city.

While Sosa trains in Philadelphia, he is proud of his hometown. He believes a strong performance could bring about positive press to a city that sorely needs it.

"I was born and raised in Camden. I'm proud of my hometown. I want to show these kids from there that you could succeed if you put your mind to it. I receive a lot of support from people in Camden and I still get a lot of love from those in Philadelphia."

Sosa may seem like he has little to lose and everything to gain on Saturday night. The ultra-relaxed attitude on the part of Sosa may be that he believes Walters is under a lot of more pressure to perform or secure a win.

He may not be known to a lot of fight fans now, but a win could thrust Sosa into bigger fights on bigger platforms.

"I don't feel any pressure whatsoever. The only thing different is that I'm fighting on a bigger stage on HBO."

"Training camp went great and I can't wait to do my thing."
