Washington Nationals third baseman Ryan Zimmerman will once again host “A Night at the Park” on Thursday, June 14 at Nationals Park. The third annual event will feature a special performance by the alternative rock band Guster as well as silent and live auctions. Proceeds from the event will benefit the ziMS Foundation, which is dedicated to the treatment and ultimate cure of Multiple Sclerosis.

Nationals Park will be transformed into an intimate concert hall for 2,000 guests. A custom stage will be
built on the outside concourse of the Presidents' Club with attendees sitting in the Diamond Club
seats. The evening will also include silent and live auctions and for VIP guests, open bar and gourmet
dinner.

The guest list will include celebrities from the sports, entertainment and political societies, and Ryan's
Nationals teammates.

The ziMS Foundation (www.zimsfoundation.org) is dedicated to the treatment and ultimate cure of
Multiple Sclerosis (MS) by funding comprehensive support and educational programs. MS is a disease
close to Ryan's heart. In 1995, his mother Cheryl was diagnosed with MS, a chronic and unpredictable
disease that affects the central nervous system. As President of the ziMS Foundation, which he
founded in 2006, Ryan is excited to give back to his community and find a cure for this debilitating
disease. The first two "A Night At The Park" events raised more than $400,000 for the ziMS
Foundation.
