Mark McGwire – Life, Career & Controversy
Explore the life of Mark McGwire: his rise as one of baseball’s greatest sluggers, record-breaking feats, later controversies, coaching, and legacy.
Introduction
Mark David McGwire (born October 1, 1963) is an American former professional baseball player and coach, best known for his prodigious home run power.
Nicknamed “Big Mac,” McGwire’s combination of raw power, selective plate discipline, and physical presence made him a central figure in the “home run era” of the 1990s.
Early Life & Amateur Career
Mark McGwire was born in Pomona, California, to a family in which his father worked as a dentist.
He attended Damien High School in La Verne, California, where he played multiple sports including baseball, basketball, and golf.
He went on to play college baseball at the University of Southern California (USC), where he shifted permanently to first base and established himself as a prolific hitter.
In the 1984 MLB Draft, McGwire was selected 10th overall by the Oakland Athletics.
Major League Career & Records
Oakland Athletics (1986–1997)
McGwire made his major league debut on August 22, 1986 with the Athletics.
In 1987, his rookie season, McGwire hit 49 home runs, setting a new rookie record at the time. American League Rookie of the Year honors.
In 1989, he helped the Athletics win the World Series.
He also won a Gold Glove Award (for defense at first base) in 1990.
Through his time in Oakland, he solidified his reputation as one of the elite sluggers of his era.
St. Louis Cardinals (1997–2001) & Peak Seasons
On July 31, 1997, McGwire was traded to the St. Louis Cardinals.
His signature year came in 1998, when he smashed 70 home runs, breaking Roger Maris’s long-standing single-season record (61).
He continued at a high level in following seasons, hitting 65 home runs in 1999 and leading MLB in home runs in four consecutive seasons (1996–1999).
McGwire formally announced his retirement on November 11, 2001, citing declining performance and injuries (especially knee problems) as factors.
By the end of his playing career, McGwire had amassed 583 home runs, 1,414 RBIs, and a batting average of .263.
He also holds the MLB record for fewest at-bats per home run (10.6 at-bats per home run).
Coaching & Later Roles
After retiring as a player, McGwire stayed involved in baseball as a hitting coach.
-
In 2010, he became the hitting coach for the St. Louis Cardinals, helping drive improvements in the team’s offensive production.
-
In 2013, he accepted the same role with the Los Angeles Dodgers, partially for personal reasons (closer to family).
-
Later, he served as bench coach for the San Diego Padres (2015–2018).
Though not as dominant as in his playing days, McGwire’s coaching work kept him influential in shaping hitters and mentoring younger players.
Controversy: Steroid Era Admission
McGwire’s league and public reputation became controversial due to performance-enhancing drug (PED) allegations.
Throughout the 2000s, he faced accusations of steroid use, including from former teammate José Canseco.
In a widely publicized 2010 interview with Bob Costas, McGwire admitted to using steroids “on and off” over a decade, including during his peak years. He expressed regret:
“I wish I had never touched steroids … It was foolish and it was a mistake.”
His admission stirred debate over how much his home run records were aided by chemistry. Critics say he never fully accounted for how PEDs inflated performance; supporters argue his natural talent and work ethic also mattered.
Because of this, McGwire has thus far not been elected to the National Baseball Hall of Fame, with most voters citing his steroid involvement as disqualifying.
Personality, Public Image & Legacy
McGwire often maintained a reserved public persona. Before admitting steroid use, he avoided media exposure and spent leisure time golfing.
He has been active in family life, marrying Stephanie Slemer in 2002, and the couple has several children (including triplet daughters born in 2010).
McGwire founded the Mark McGwire Foundation for Children, focusing on supporting children who have experienced abuse and hardship.
