On June 14, the Tigers and Pirates wore throwback uniforms to commemorate the 100th anniversary of both Forbes Field and the 1909 World Series between the two teams. That game also featured a throwback atmosphere: no music or flashy graphics, no mascots (meaning no Jolly Roger or Pirate Parrot), and a hand-operated scoreboard. One modern item occurred in the pre-game: The Stanley Cup champion Pittsburgh Penguins made a surprise visit and brought the trophy with them. The Pirates and the Kansas City Royals also honored the Negro leagues on June 26 and 27 with the Pirates wearing the Homestead Grays uniforms and the Royals donning Kansas City Monarchs replicas. The Pirates and the Cincinnati Reds recreated their 1979 National League Championship Series uniforms on August 21 as part of the Buccos' 30th anniversary celebration of their World Series championship. The Bucs wore their gold pillbox hat with a gold jersey and black pants, a faux pas from the uniforms that season as a black cap was worn that year with the gold jersey.
