Pitchers always seem to be drafted in bunches in the MLB draft, so I went and looked up past drafts and here is what I came up with.
2004 - 53% were pitchers (I know you said 56%, I counted twice)
2003 - 46%
2002 - 51%
2001 - 53%
2000 - 57%
1995 - 50%
1990 - 45%
1985 - 47%
1980 - 46%
For most of the last 10 years, pitchers have been going at around 52%, so 2004 was a little high but I think its a bit early to signify the start of a big change. If the trend continues upward then we could look back and say that this was the begining.
From my data it looks like a change was made in the early 90's toward more pitchers being drafted.
I believe there ought to be a constitutional amendment outlawing Astroturf and the designated hitter. -Crash Davis
