Her's how optimistic Matty is about Haniger: A couple of threads back he opined a .275-.340-.490 line for Haniger.
In the long and not-so-storied history of the Seattle Mariners, only fifteen times have fulltime OF's (125 games in the OF--550 PA/162) had a line that was equal to or better than the Matty Line. Well, actually my baseline search was .270-.340-.475. I made 20 HR's part of the search, as well. But if you drop the homers to 18 and the OBP to .320, the results are the same.
Only 15 times: 8 of them were by a Kid named Griffey, three by Ibanez, two by Buhner, one by Bradley and one by Winn. Oh, if I drop all the way down to 535 PA/162 I can add another, Leon Roberts in '78.
All but five of those season were in the HomerDome.
If Haniger hits Matty's mark, it will be one of the great seasons by a fulltime M's OF in the team's history. Factor out Griffey and then you really see how rare it is.
