Mark your calendars! The 21st annual City of Hope Celebrity Softball Challenge has been set for June 11 at Nashville's Greer Stadium. The tradition is one of many events held during the CMA Music Festival, which will take place June 9-12.

In what has become a longstanding rivalry, the Grand Ole Opry will go head-to-head with After MidNite With Blair Garner in the friendly competition that supports the City of Hope. Stars including Carrie Underwood, Vince Gill and Josh Turner have flexed their athletic prowess in the past to support research, education and treatment for cancer and chronic illness patients.

Tickets are now available in $15, $20 and $50 increments. The $50 Super Fan package includes a limited edition Hatch Show Print and the chance to join the on-field game shenanigans. In addition, an online auction of exclusive autographed memorabilia will be posted after the game at www.auctionsforhope.org
