The Baltimore Sun is reporting that Under Armour and Ripken Baseball Inc. are forming a business alliance that will be unveiled at a news conference Wednesday at the Sports Legends Museum at Camden Yards. 

Ripken Baseball is a marketing and sales company run by Cal Ripken Jr., the former Baltimore Orioles third baseman.

Details of impending announcement were not disclosed, but the Sun said sources familiar with the deal indicated that Under Armour will have “a substantial presence at Ripken's baseball properties, which include three minor league franchises, in Aberdeen, Augusta, Ga., and Port Charlotte, Fla., and perhaps more importantly, at two youth training facilities in Aberdeen and Myrtle Beach, S.C.”
