Semi-pro boxers make for great storylines at Saturday’s fight night.

The Macy’s make-up girl, the New York bartender, the reformed street thug and the collections agent have something in common. They will all attempt to beat the crap out of someone this Saturday at the “Collision at the Conference Center.”

Welcome to the world of small-time professional boxing.

Hector Saez will set aside his day job in the call center of a collections agency long enough to hop a flight to Monterey and square off against local hero Jesus “Chuy” Rodriguez.

Rodriguez is the only full-time pro boxer of the bunch. Thanks to a cult-like local following and top-notch management, Chuy has overcome a troubled history that has included gangs and jail time to establish himself as an up-and-comer in the Jr. Welterweight division.

His opponent, while coming from a similar background, hasn’t enjoyed the same success. Saez describes himself as a streetfighter, trained in the orange glow of Manhattan streetlights.

“I grew up [fighting] on the streets, until somebody said, ‘You can get paid to put padded gloves on and fight.’” Now Saez is a customer service agent by day, pro boxer by night.

He isn’t the only one throwing the unconventional combo. Unable to get off work, Kaleisha West conducted her pre-fight interview from the break room of Macy’s. “I explained it to my boss,” she said. “He let me take my 10-minute break.”

Asked how she would react upon seeing a shoplifter, West, 18, replied, “I’d run up and knock him out.”

Her opponent, Stella Nijhoff, is almost twice her age. Nijhoff works as a bartender in New York City.

With the exception of Chuy, none of the fighters appearing Saturday earn enough boxing to make a living. Yet they train relentlessly for months before a fight.

This is their leisure and recreation, a unique and violent hobby. “It’s definitely not for the payday,” Saez said.

THE COLLISION AT THE CONFERENCE CENTER happens Saturday, Nov. 18, at the Monterey Conference Center, 1 Portola Plaza in Monterey, at 7:30pm. $40-$85. 688-1604.
