The Hall of Famer died in January at the age of 82.
The event, called “A Celebration of Earl,” is scheduled to include a video tribute and several guest speakers, including former Orioles players Brooks Robinson, Frank Robinson and Rick Dempsey, as well as current Orioles manager Buck Showalter, Baseball Hall of Fame president Jeff Idelson, and Earl's son Mike Weaver.
Gates A and H will open at 1 p.m. for the event, and complimentary parking will be available in Lot B/C. The program is free.
Once the event has concluded, the ballpark will be closed, and it will reopen at 5 p.m. for that night's game against the Los Angeles Dodgers.
