Why is a fourth starter even needed? When your starters don't even average 5 innings just make everyone a relief pitcher.
Firstly, the game that you claim has become a joke because of a lack of starter depth has produced a world series of:
Cole vs Scherzer
Verlander vs Strasbourg
Greinke vs Corbin
I'm no baseball historian, but when was the last time you had a world series with match ups that good?
Secondly, why is throwing 7 innings not a joke, but throwing 1 inning at 97 - 98 with the ball moving a foot not a joke?
Just because something is different to what you grew up with doesn't make it a joke.
Now excuse me while I get off your lawn.
