Baseball's 'Shot Clock' Coming to 2015 Home Run Derby

It's quite obvious why the MLB Home Run Derby has attracted large audiences since its establishment in 1985. Who wouldn't want to see the game's best sluggers hack away at baseballs and send them to unthinkable distances?
But the derby has had one consistent problem over the years: its length. Take last year, for example. ESPN's telecast included Chris Berman's signature “back, back, back,” home run call for more than three hours.
