Home Run Derby
The Home Run Derby is an annual home run hitting contest in Major League Baseball (MLB) customarily held the day before the MLB All-Star Game, which places the contest on a Monday in July. Since the inaugural derby in 1985, the event has seen several rule changes, evolving from a short outs-based competition, to multiple rounds, and eventually a bracket-style timed event. It is currently sponsored by T-Mobile, a wireless cellphone company.
