Right Field
2008 Travis Buck 172 PAs .226 .291 .432
2008 Ryan Sweeney 292 PAs .286 .350 .383
This is probably the A's best bet for an improvement for a returning player. Buck hit .288/.377/.474 as a rookie in 2007, and whie he may have been playing over his head a little, his minor league numbers do not suggest that his 2007 was a complete fluke. Even if you split the difference between Buck's 2008 and 2008 you get a .265/.347/.459 hitter, which is much better than what A's right fielders produced last year.
