The more I look at Zach Duke's stats, the more I'm convinced this season is a statistical anomaly. Ever since his terrible 2007 year, he has been steadily improving his statistics. I'll post some of his translated statistics, going chronologically from left to right.
ERA.: 5.80, 4.81, 3.90
H/9: 13.6, 10.9, 9.8
K/9: 3.1, 3.4, 3.8
BB/9: 1.5, 1.7, 1.8
The biggest jump in statistics is his H/9 and ERA, going from a terrible 5.80 and 13.6 to 3.90, 9.8. This might seem like Zach is bettering himself, but we all know the crazy deal about hits; who knows if they are due to a bad defense or bad pitching?
We can also see that Zach's delta numbers for this year are all in the negative. He is letting up less hits and less runs than his statistics say he should. However, I feel it is worth pointing out that he rarely has a positive DR. That's right, even in a year with an ERA of 5.80, he still should have given up more runs.
From the looks of it, Zach is consistently lucky, and luck is nothing one should ever take to the bank. If Zach somehow repeats this year next year, would it be wise to trade him? This is a big question I've had for a while. Luck has always been on Zach's side even when terrible, but if he still progresses next year despite what luck has to say about it, could it just be said that Zach transcends the boundaries of modern statistics?
