Over the past decade, Pam Shriver's Charity Tennis Classic has become Baltimore's premier charitable sporting event and a cornerstone on area planning calendars. With community-wide support, the PNC Tennis Classic presented by The Baltimore Sun funds diversified activities all targeted towards children‘s related causes. Since 1986, over $4 million has been donated to area children's charities.
The Tennis Classic has been played at the Baltimore Arena since 1990 and has attracted enthusiastic "standing room only" crowds. The event has also been televised regionally on a tape delayed basis since 1992.
The Tennis Classic's list of alumni reads like a "Who's Who" in Tennis. Past participants include Andre Agassi, Pete Sampras, Venus and Serena Williams, Anna Kournikova, Lindsay Davenport, Jana Novotna, John McEnroe, Jimmy Connors, Jim Courier, Todd Martin, Chris Evert, Martina Navratilova, Monica Seles, Andy Roddick, Mary Pierce, Gabriela Sabatini, Arantxa Sanchez Vicario, the Jensen Brothers and, of course, Pam Shriver. Renowned celebrities like "Dr. J" (Julius Erving), Kenny Rogers, Cal Ripken, Jr., Sugar Ray Leonard, Roberto Alomar, Brady Anderson, Tony Siragusa, B.J. Surhoff, Mike Bordick, Trent Dilfer and Shannon Sharpe have played in the Tennis Challenge's celebrity doubles match.
Founded in 1986 to benefit the Cystic Fibrosis Foundation, Pam Shriver's leadership and guidance has enabled the Mercantile Tennis Classic to expand its charitable commitment to the community. In 1993, the Tennis Classic Fund was established at the Baltimore Community Foundation. A publicly supported endowment for the Greater Baltimore region, the Community Foundation awards charitable grants to non-profit organizations throughout Central Maryland. The Tennis Classic fund targets non-profits that work to enhance and improve the lives of the region's youth through education, physical fitness and health/mental health. Under the guidance of the Community Foundation and the Tennis Classic's Executive Committee, grants have been awarded to the following non-profits among others, since the Tennis Classic Fund was established.
