Jeff Bagwell, American baseball player and coach
Jeffrey Robert Bagwell (born May 27, 1968) is an American former professional baseball first baseman and coach who spent his entire 15-year Major League Baseball (MLB) playing career with the Houston Astros.

Originally a Boston Red Sox fourth-round selection from the University of Hartford in the 1989 amateur draft, Bagwell was traded to the Astros in 1990. Bagwell was named the National League (NL) Rookie of the Year in 1991 and won the NL Most Valuable Player Award (MVP) in 1994. Bagwell and longtime Astros second baseman Craig Biggio were known as the "Killer B's", and the team experienced consistent success during their careers; Houston finished in first or second place in the NL Central division in eleven of twelve seasons from 1994 to 2005. During that period, the Astros qualified for the playoffs six times, culminating in Bagwell's lone World Series appearance in 2005.

Bagwell hit 449 home runs for the Astros, the most in club history, and set numerous other franchise career and single-season records. He is a four-time MLB All-Star, a three-time Silver Slugger winner and a Gold Glove recipient. The only player in MLB history to have six consecutive seasons (1996–2001) with thirty home runs, 100 RBIs, 100 runs scored, and 100 walks, Bagwell is one of twelve players in history to hit 400 home runs and record an on-base percentage (OBP) of .400. He is the only first baseman with at least 400 home runs and 200 stolen bases. Overall, Bagwell batted over .300 six times, had a career OBP of .408 (39th all time), and had a slugging percentage of .540 (32nd all time). He was elected to the Texas Sports Hall of Fame in 2005, and to the National Baseball Hall of Fame in 2017.
