In honor of Asthma Awareness Month, the Phillies are holding a special evening at Citizens Bank Park devoted to keeping Philadelphians healthy and informed on the subject.

In conjunction with the Know Your Count campaign, an initiative whose goal is to promote knowledge of how many doses are available in an individual asthma sufferer's inhaler, Emmy and Tony award-winner Kristin Chenoweth will sing the National Anthem around 6:40 p.m. at Tuesday, May 6's Phillies game against the Toronto Blue Jays. Diagnosed with asthma ten years ago, Chenoweth works closely through Know Your Count, helping encourage patients to have an emergency inhaler with a dose counter.

Throughout the course of the game on the first and third base stadium entrances, game attendees will have access to free asthma screenings.
