PITTSBURGH — Charlie Muse, a longtime Pittsburgh Pirates executive who created baseball’s modern batting helmet, has died.Muse died May 5 in Sun City Center, Fla., at age 87, the Pirates said. He had lived there since retiring in 1989 after 52 years with the team — many as the team’s traveling secretary.Until former Pirates general manager Branch Rickey pushed in the early 1950s for the creation of a protective helmet, batters traditionally wore only their cloth caps to the plate. At the time, Rickey owned American Baseball Cap Inc., and he chose Muse to run the company and design a suitable helmet.
