The impending arrival of the Double-A Baysox at Memorial Stadium may open a whole new vista to collectors. It's a new team with a new logo -- and an array of merchandise collectors can check out before Opening Day. The Baysox's ticket office in the lobby at Memorial Stadium also serves as souvenir headquarters -- with advance sales of T-shirts and other popular items. But don't be surprised if you see the Baysox's logo sold in stores far from the Chesapeake Bay. General manager Keith Lupton says that Major League Baseball Properties licensees are authorized to manufacture items bedecked with minor-league team logos. In turn, minor-league teams receive royalty payments. "If a logo gets hot, you can make some money," says Lupton, who adds that one of his favorites is the Chattanooga Lookouts' capital C with a pair of cartoon eyes. The Baysox's cap logo has a capital B with a sail and baseball. Its primary colors are red, black and teal. "A lot goes into that logo," says Lupton. "Do you want to go into a cute logo . . . or a traditional logo? We chose to go with a traditional logo because it might be around longer." He says another consideration was to make it marketable across the country and that J. C. Penney is considering merchandise with the Baysox logo. Among the items the team will sell are eight T-shirt designs, a half-dozen different caps, coffee mugs, steins, logo balls, tankards, sweatshirts and trolls. It's a far cry from Lupton's early days in minor-league administration. "When I got into minor-league baseball in 1981, [the souvenir stand] was just a little cubicle," he says. Now team merchandise is an important revenue source, along with tickets and food. Collectors who attend Baysox games will be in for a triple treat. Maryland Baseball Limited Partnership owns the Frederick Keys as well as the Baysox, and some Keys merchandise will be sold at Memorial Stadium. The Baysox plan to sell some Orioles items, too. Fans at Camden Yards will be able to buy items from Orioles farm clubs this year. Lupton says three items from each team will be available -- caps, T-shirts and one item of the farm team's choosing. Collectors outside the Baltimore area can write to the Baysox for a souvenir list at Memorial Stadium, 900 E. 33rd St., Baltimore, Md. 21218-3646.
