Baseball

• May 5: Boston Americans ace Cy Young pitched the second of his three no-hitters, a 3-0 perfect game against the Philadelphia Athletics and pitcher Rube Waddell (the final batter he faced). Young will eventually complete 24 straight hitless innings, still the record, and 45 shutout innings in a row, a mark until broken by Jack Coombs' 53 scoreless frames in 1910. This is the first perfect game of the modern era.
