Mark David McGwire (born October 1, 1963), nicknamed Big Mac, is an American former professional baseball player and currently the bench coach for the San Diego Padres. As a first baseman, his MLB career spanned from 1986 to 2001 while playing for the Oakland Athletics and the St. Louis Cardinals. He quickly grabbed media attention in 1987 as a rookie with the Athletics by hitting 33 home runs before the All-Star break, and would lead the major leagues in home runs that year with 49, setting the single-season rookie record. He appeared in six straight All-Star Games from 1987 to 1992 despite a brief career decline related to injuries. Another string of six consecutive All-Star appearances followed from 1995 to 2001. Each season from 1996 to 1999, he again led the major leagues in home runs.
