On Tuesday at 3 p.m., Nationals reliever Collin Balester will chat with fans online at ESPN.com. Balester will discuss his effort to grow a mustache for Movember, a project that raises funds for prostate cancer research. He'll take questions on the cause, his community involvement, pitching, the Nationals, teammates and whatever else you want to know. Fans can still donate to his Movember page or read more about his efforts to support this cause.
