Barry Bonds
United States
American Barry Bonds hit his 762nd career home run on August 7, 2007, against the Washington Nationals, surpassing Hank Aaron's record of 755. However, the record remains one of the most contentious in MLB history due to steroid-use allegations. Bonds also holds the single-season record of 73 home runs set in 2001, and his career numbers -- a .298 batting average and 1.051 OPS -- were dominant even setting the doping controversy aside.
