Andy Roddick once got paid exclusively from his work on the tennis court, but occasionally some loud, brash opinions came as a byproduct.

Now, he derives most of his income from his opinionated mouth, with some tennis occasionally on the side. Such has been and remains Roddick’s charmed life.

Roddick, 31, who retired from professional tennis in 2012 and now co-hosts a flagship show on Fox Sports 1, will play tennis again Wednesday night at the Pepsi Center.

The itch to play at least some competitive tennis again led Roddick to join this year’s PowerShares Series, a.k.a. the senior tour of the sport. Roddick will play Mark Philippoussis in one semifinal match, Jim Courier against James Blake in another and the winners playing for the night’s title.

Why did Roddick want to pick up a racket again so soon, despite what has been a successful reinvention as a sports media person and an active charity foundation in his name?

“There’s no way to replace playing in front of a crowd and kind of the feeling that gives you,” Roddick said. “And I have a lot of other interests right now, which are very fulfilling, but nothing will ever replace being able to play live sports. Yeah, I didn’t expect it to. But this is a chance for me to do it, I guess, more in a little bit of a part-time scale. I’m looking forward to it. It’s always fun to play with guys that have been so accomplished in the sport.”

Roddick was the No. 1 player in the world after winning the U.S. Open in 2003. He played in Wimbledon finals in 2004, 2005 and 2009, losing all three to Roger Federer. Roddick was known for his crushing serve, which sometimes exceeded 150 mph. In 2009, he married Sports Illustrated swimsuit cover model Brooklyn Decker. Elton John sang at the wedding.
