(Washington D.C.) -- MASN, the local leader in live sports entertainment, will conduct open auditions for future spots in the network's Defining Moments advertising campaign. The innovative campaign, which launched at the beginning of the 2009 season, features real, everyday fans describing their favorite memorable baseball moments - in their own words. Fans of both the Washington Nationals and the Baltimore Orioles can audition at Nationals Park on May 23rd and at Oriole Park at Camden Yards on May 30 to star in a MASN commercial later this summer. Fans may also submit their Defining Moments videos and blogs at MyMASN.com for consideration.

Auditions will start 90 minutes prior to the first pitch and continue throughout the game at MASN's booth in each ballpark. At Nationals Park, MASN's booth is located on the concourse level near first base. At Camden Yards, fans can find MASN on Eutaw Street by Gate A. Participants should bring a Defining Moment or story about their favorite game or player. MASN will ask each fan to improvise their Defining Moment and to read some prepared lines.

Selected participants will be called back for a second round of auditions in early June, with final shooting to take place during the second week of June. Approximately 20 new fans will be chosen to "star" in the next round of Defining Moments commercials for MASN, which are scheduled to hit air in early July, around the time of baseball's All Star Game.

The first series of Defining Moments spots can be viewed on MASN and at mymasn.com. Over 200 fans submitted their defining moment online, while several dozen were selected during open auditions at Nationals Fan Fest. Fans came from Charlottesville and Richmond, New York and Connecticut, Pennsylvania and the Baltimore-Washington area to participate in the campaign.

"Baseball fans are passionate about their favorite teams, and their love for the game is on display throughout this innovative, season-long campaign," said network spokesman Todd Webster. "MASN saw a unique opportunity to let real fans star in these spots because their baseball experience is authentic and their passion is infectious. We invite all Nats and O's fans to submit their favorite moments and to audition to be in their own television ad."
