CINCINNATI (AP) — The Cincinnati Reds are fashionably celebrating the 150th anniversary of the professional baseball-pioneering Red Stockings team.

Joey Votto and crew will play games in 15 sets of throwback uniforms, including a navy blue and a red-pants “Palm Beach” version, during a season-long celebration of the city’s baseball heritage highlighted by the undefeated 1869 Cincinnati team that barnstormed coast-to-coast in post-Civil War America. Baseball’s first openly all-salaried club, the Red Stockings popularized eye-catching uniforms with knicker-style pants and bright red socks while elevating the sports with a variety of innovations.

“From a historical point of view and in the evolution of baseball as the national pastime, the 1869 Red Stockings were the cornerstone,” said Greg Rhodes, the Reds team historian and co-author of “The First Boys of Summer.” ”It’s hard to imagine the modern game of baseball without the Red Stockings.”
