#GOOD PITCHING REPERTOIRE HOW TO#

For the former, you will find me glancing at their K-BB% (and K% and BB% alone), HR/9, and their ERA, FIP, xFIP, and SIERA. That should require a quick glance at FanGraphs and Baseball Savant. Obviously, we want to get a quick look at a player to see if it’s worth looking into any further. Here, I’m going to do my best to get across what I’ve learned about evaluating pitchers, but given the fluid nature of pitching analysis, it would be impossible to get into everything I do, because after my preliminary analysis it is a completely different process for every single pitcher I evaluate.

I feel like my analysis chops have improved exponentially in the past year and a half at Pitcher List, and that’s due to because I’ve done everything I can to gauge what situations it’s appropriate to use certain metrics, when it is not, and how to be efficient in my analysis. Sometimes I’m right, sometimes I’m wrong, but I always lean into whatever I’m feeling. In learning from them, I’ve learned to use advanced statistics more appropriately, which has led to me feeling more strongly about players - whether that means liking or disliking them. You’ll notice that we all have different niches - this is why, say, Jeff and Nick talk about pitching from different perspectives, and often come to slightly different conclusions. I’ve learned a great deal from Eno Sarris and Alex Chamberlain as well. I was full of deluded confidence.Īs an analyst, I consider myself from the school of Jeff Sullivan, and more recently Nick Pollack. Come to find out, I was misusing all of these tools all along, and that led to me putting misguided faith in players that I should not have been confident in, as well as distrust in players that I should have liked. Then, I learned to lean on Statcast data more recently, using xwOBA and the like to get ahead.

As a fledgling analyst in college (in the early-to-mid-2010s), I thought I was ahead of the curve by using SIERA when my peers did not. Over the years, I have learned many things about evaluating players, but especially pitchers.
