2021 Pod vs Steamer — ERA Upside
This week, I finish up the Pod vs Steamer series that pits my Pod Projections against the Steamer projections. Today, we move on to pitchers, where I’ll compare the ERA forecasts from each of the systems and identify those pitchers I am projecting for significantly better ERA marks. Though Steamer is the best pitching projection system out there, it struggles on pitchers that have shown consistent BABIP and HR/FB rate suppression skills and deficiencies, as what usually works for the majority of pitchers — projecting a heavy dose of regression to the MLB mean — means it misses on those uncommon exceptions. I use Statcast’s xBABIP now for my projections, so I’m not afraid to forecast a mark that strays from the league average. However, I certainly still include some regression as we don’t always have enough batted balls in a pitcher’s history for that mark to stabilize.
