Every now and then, I need to refresh my memory on what the baseline stats are for various pitch types, and that brings me back to this piece on pitch type performance from fellow RotoGrapher Alex Chamberlain. I am not only reminded of how inferior sinkers generally are at inducing whiffs and preventing hits on balls in play, but of Alex’s advice to pitchers: “Seriously, don’t throw a sinker.”

But, of course, lots of big league pitchers do, and 33 of them threw at least 500 sinkers in 2019. Given that pitchers stand to give up fewer hits if they switched from their sinker to another offering — assuming their version of that alternative pitch was at least decent — it seems like pitchers who ditch or de-emphasize their sinker should get more attention for doing just that. It also would seem that more pitchers would make that change. In every year of the 2010s, there were no more than 10 pitchers in a given season who decreased their sinker usage by 10 percentage points or more (and also threw at least 100 innings both the current and previous seasons).

It is time for an update to my starting pitcher ranks for 2020. I will be discussing some of these with Paul Sporer and Nick Pollack on tomorrow’s Sleeper and the Bust Podcast, so definitely listen to that.

All ranks are based on 15-team standard leagues. ADP is from ADP and reflects Online Championship’s data since 1/1/2020. For more ranks of mine for 2020, you can click the links below: Read the rest of this entry »

Yesterday, I used my pitcher xK% equation to highlight four starting pitchers whose underlying skills suggested a dramatically higher strikeout rate than actually posted, hinting at upside this year if the pitcher could maintain those skills. Today, let’s talk about the starting pitchers who most outperformed their xK% marks, heightening the risk of a decline this season, absent an improvement in underlying skills.

Three years ago, I shared an updated version of my pitcher xK% metric, which correlated strongly with actual strikeout rate, given its 0.931 R-squared. While some of my other xMetrics I calculate and then use them to serve as a historical guide to assist in my Pod Projection forecasts, I actually project the underlying components of xK% myself and the vast majority of the time, keep the projected strikeout rate those components spit out. There are instances where I do change the forecast though, as some pitchers have a history of outperforming or underperforming their xK% marks, for whatever reason. Anyhow, let’s discuss four starting pitchers who posted xK% marks above their actual marks, hinting at some upside this year.

I got the idea for this post while writing a player caption for Nate Eovaldi (more on him in a moment). As I outlined the glass half full scenario for the upcoming season, it occurred to me that 1. Eovaldi is free even in the deepest leagues and 2. pitchers like Eovaldi sometimes spontaneously become useful. Excellent even.

Charlie Morton and James Paxton immediately came to mind – they were always injured and then suddenly they found health and reached acedom (*cough* Paxton is broken again). Those are just two poster children for the upside. Carlos Carrasco, Hyun-Jin Ryu, Lance Lynn, Mike Minor, Eduardo Rodriguez, Frankie Montas, Jameson Taillon, and Homer Bailey are all variations of this profile.

And so, without further ado, I present five always broken starting pitchers who might just might have something left to give.
