It is entirely possible that Zach Greinke is a better pitcher at home, and entirely possible he just has lucky results there this season.You're right. The problem is, people cling to his home/road splits like they are the word of God, handed down to Moses on two stone tablets. There might be something there, there might not be, but rather than saying that nobody has found a real reason why his splits are what they are over less than 30 games, people just conclude that Greinke MUST start at home because zomglookatthesplits.
