The past 3 years Suppan has thrown 3.8, 3.6, 3.7 pitches per PA. Vargas has thrown 3.8 the past 2 years. Sheets has thrown 3.8, 3.6, 3.7 Doug Davis has thrown 3.9, 3.9, 3.9 Randy Johnson 3.8, 3.7, 3.8 Zito - 4.0, 4.0, 3.9 The point is, I don't think the K's drive it up nearly as much as walks do. They seem to be the limiting factor on how deep into the count things go. The other factor is how many total batters are faced and with that high WHIP suppan faces a lot of batters.
