I have Wells, Wakefield, and Marquis all under 2.00 ERA, they have on ave. 1.7 to 1 GB/FB ratios. Thus we can't just say groundball pitchers are getting screwed.

I would expect all pitchers to have a slightly higher ERA due to less DP's.

I'd expect early season lefty/righty platoon effects having the greatest effect right now. That plus luck with so few innings.
