Fant. baseball infield and outfield?

first year playing fantasy baseball wondering how my picks turned out. i'll give you the player and what round i selected them. thanks for any input. RD 1 grady sizemore(OF) RD 2 chase utley(2B) RD 3 adrian gonzalez(1B) RD 4 armis ramirez(3B) RD 5 joe mauer(C) RD 6 jacoby ellsbury(OF) RD 7 michael young(SS) RD 8 hunter pence(OF) rounds 9-15 i drafted my pitchers. they are avg. with 2 good closers, need to study my pitchers more. RD 16 lastings milledge(OF) RD 17 kazuo matsui(2B) RD 18 willie taveras(OF) RD 19 kelley johnson(2B) RD 20 ryan theriot(SS) RD 21 a.j. pierzynski(C) was wondering what to look for after my core players, i tried to address specific categories but it always seemed like i was pressed for time. also did i take a catcher to early? harder to pick for baseball than football or basketball. thanks for any help.
