Being the general manager of a minor league baseball club can be a pain in the rear sometimes.

Just ask Charleston RiverDogs general manager Dave Echols.

Echols has agreed to undergo a prostate exam while singing "Take Me Out to the Ball Game" in the seventh inning of Saturday's game between the RiverDogs and the Hagerstown Suns.

The game is scheduled to start at 6:05 p.m.

Echols has agreed to participate in the "Two-Knuckle Challenge" if fans can push the "Fierce Fallon" Facebook page to 13,000 likes by Saturday's contest.

Fallon Emery is a nine-year-old girl from Carolina Forest who is fighting brain cancer and receiving her treatments at MUSC.

Earlier this month, Myrtle Beach Pelicans general manager Andy Milovich received an in-game prostate exam as he sang "Take Me Out to the Ball Game" during a baseball game.

"Joining the 'Two-Knuckle Challenge' in support of Fallon Emery is a unique way to back this important cause," Echols said. "As a minor league baseball franchise, multi-tasking is nothing new for us, but a prostate exam while singing during the seventh-inning stretch is definitely a distinctive endeavor. I just hope that once we get enough likes for 'Fierce Fallon' that I can pull through this exam with a clean bill of health."

Fans can go to the "Fierce Fallon" page on Facebook (www.facebook.com/fiercefallon) and learn more about her battle against brain cancer.
