Pitching can be the spot of our lineups where we experience the lowest degree of variance in a sport full of volatility. We’re not going to explore how to minimize variance, but how to make the best plays tailored for our lineups to fit the contests we’re playing using projections and leverage.
A lot of things factor into a pitcher scoring fantasy points via strikeouts, innings, and run prevention. A pitcher’s skill is pretty important, but what’s the best way to gauge a pitcher’s skill? The answer is mostly through the predictive analytics of their past performance, which ought to be distinguished from the descriptive analytics.
Projection
We get fantasy points for outs, Ks, and Ws (on FD, we also get the points for the QS); it’s that simple. We lose points for ER on both sites, baserunners on DK. Keep it simple. Find a predictive run prevention metric between xERA, FIP, xFIP, or SIERA. Decide between the per-nine rates or per-100 batter-faced stats like K/9 versus K%. I prefer xERA, based on the Statcast numbers, or SIERA, as they isolate that over which the pitcher has the most control. I prefer K/9 because K% can double-count for events already recognized in the run preventers, as we’re really just looking to project Ks with that metric.
