On May 8, 1901, In their long-delayed American League home opener, Boston defeats Philadelphiaâs Bill Bernhard, 12 â 4, behind Cy Young, who has jumped from the St. Louis Cardinals. Boston is led by Buck Freeman, who has a single, triple and homer. Young complains that he does not like the rule against pitchers warming up, but he will still lead the AL with his 1.62 ERA. His 33 wins are 41.8 percent of his teamâs 79 victories; a post-1900 record, it will stand until Steve Carlton wins 45.8 percent of the Philsâ 59 wins in 1972. Young also complains about catchers: âI do not like the league rule compelling the catcher to stand behind the bat all the time. It handicaps a pitcher. I cannot extend myself as I would like.â
