12. Tom Gamboa – 2002
One of the most outrageous fan assaults ever, this was disgraceful attack. Gamboa was the first base coach for the Kansas City Royals when a pair of fans assaulted him. The team traveled to Chicago for a game against the White Sox. The Royals were leading 2-1 when a father and son duo hopped the fence and targeted Gamboa.

William Ligue and his son, William III, violently attacked him for no reason. The veteran coach suffered permanent hearing loss in one ear. Meanwhile, the pair of cretins went to jail. Over the years they’ve been in and out of prison for drug offenses, DUIs, and petty crime. But Gamboa unfortunately lives with the consequences of their actions.
