Personally I stay away from pitchers until later due to increasd injury risk. Recently read an article backing this up.
Here's the exerpt from the article:
"At least 80 percent of your budget goes to hitting
You've probably already heard the old adages that go something like: "Pitching is riskier, so spend more on hitting." How about some numbers instead: Studies have shown that as much as 30 percent or more of the eventual pitching value in a league, is not available on draft day (meaning on Opening Day rosters). Hitting tends to run around 10%. You have a much better chance of finding quality pitching than hitting in the free-agent pool. Thus, spend a lot on hitting on draft day."
