Pitch Counts and Strike Percentage

I started tracking pitches thrown in 2003, though I have charts well into the 90's. Here are some numbers:

..............Strike Pct......Pitches/Inning
2003... 60.6...................15.7 (18-5)
2004... 62.8...................15.5 (28-9)
2005... 63.6...................15.4 (17-10)
2006... 62.2...................16.9 (12-12)
2007... 60.2...................15.8 (13-4)

I might see if I can find some numbers on some of our standout performers of the past 15 years.
