The Indians Are Missing The Easy Ones
Pitching and defense are inextricably intertwined, and that shouldn’t be a controversial statement. Any pitcher who isn’t striking out 100 percent of the batters he’s facing is relying on his defense for help. Any defense can only do so much to stop an opposing offense when their pitcher is giving up an endless amount of homers and line drives. It all comes together as run prevention, which is a team effort, and it’s why we have things like FIP & xFIP and de-emphasize or totally ignore things like ERA & wins that attempt to give the pitcher all of the credit (or blame).
That being the case, sometimes it’s fun to look at ERA-FIP, which shows you the gap between the two, and is a nice rough way to look at what pitching staffs are being helped (or not) by their defenses. Ideally, the teams with the biggest gaps, in either direction, should correspond to the teams with great or terrible defenses. If you look at starting rotations in 2014, you’ll see a few things stand out. First, you’ll notice that the Diamondbacks have an ERA 2.00 runs higher than their FIP, which is probably less about defense than it is about the fact that they’re a flaming dumpster fire that, if they keep things up like this, will give me a nice juicy “this is among the worst rotations ever” topic in a few days. But among teams functioning on some plane of reality, you’ll see that the Indians are the next-worst team, with an ERA 1.62 runs higher than their FIP, and that the Braves are the best, with an ERA 1.42 runs below their FIP.
