"I was a little nervous, but after a few minutes I got over it," said Mayen. "I was just happy to make my debut. I've worked really hard this last year and to be with the first team is a dream come true."
The young midfielder, who turned 20 a couple of months ago, continued: "I grew up playing in L.A. on dirt fields. One year, I played in the state cup and some Olympic Development coaches took a look at me. That's where I got my chance to start playing somewhere else.
"At the end of last season, the coaches told me to get stronger and I'd improve," said Mayen. "So I got a personal trainer and stayed in shape in the offseason. This year, I see the results from the hard work I did."
