While his image has been tarnished by steroid use, there is no denying that Barry Bonds was an absolutely dominant hitter in Major League Baseball. In 2004, Bonds hit a still-record 73 home runs in a single season. 2 years after that, teams were so scared of him that they walked him 232 total times, with a whopping 120 of those walks being intentional. That remains the record for most intentional walks in a season. In 2004, Bonds reached 1st base 376 times and only had 373 official at-bats.
