McGwire led the major leagues in home runs in five different seasons, and set the major-league record for home runs hit in a four-season period from 1996 to 1999 with 245. He demonstrated exemplary patience as a batter, producing a career .394 on-base percentage (OBP) and twice leading the major leagues in bases on balls. McGwire also led the league in runs batted in once, on-base percentage twice, and slugging percentage four times. Injuries cut short even greater potential, as he reached 140 games played in just eight of his 16 MLB seasons. Injuries particularly cut into his playing time in 2000 and 2001 and factored into his decision to retire. A right-handed batter and thrower, McGwire stood tall and weighed during his playing career.
