Last year the K's went way down but so did the walks and the result was an even better whip and era.
Checking the numbers, this is just not true. He struck out 152 in 2002, 162 last year. He walked 62 in 2002, 61 last year.
That's just me being anal.
I like Hudson, despite the fewer K's. He's on pace now for around 115 strikeouts, 40 walks. The fewer walks has definitely helped him. He's also on pace to allow fewer home runs than any full season he's pitched so far. It's possible he's making a conscious decision to be more economical with his pitches, so he can stay in games longer, maybe because the A's bullpen isn't as good as it's been the last few years. He's averaging more innings pitched per start than in any other year, but with about the same number of pitches per start.
