Pitcher Valuations: Single Season Projections & pERA Values

After focusing the 2021 prep on hitters for the last couple of weeks, it’s time for pitchers to take center stage. There is no way to hide that the following is mostly a data dump with a small bit of analysis. Welcome to mid-October 2021 draft prep.

Single Season Projections

These projections are about as simple as it gets. It takes a pitcher’s 2020 results and projections the pitcher going forward based just on those stats. With some pitchers completely changing their pitch arsenal, I find these projections are a better evaluation tool than multi-year averages. For a reference, here is the full write up on how they are created.

Starting Pitcher Fastball Velocity Decliners — 7/28/20, A Review

Yesterday, I reviewed how the starting pitchers that increased their fastball velocities the most after their first start fared over the rest of the season. Today, let’s check in on the velocity decliners. Since the article was typed on July 27, that means it includes velocities through July 26. Did these pitchers rebound off their first start declines?

Starting Pitcher Fastball Velocity Surgers – 7/27/20, A Review

Performing backward looking analysis with the intention of using it for forward looking actionable advice is only as good as the success of the advice. So I always make sure to look back on the season and review all the analysis I performed and the advice it drove. We know that fastball velocity is very important for pitchers and that it also stabilizes pretty quickly, meaning we don’t need many pitches to learn valuable information. So early on in the season, I posted several articles highlighting fastball velocity surgers and decliners. Let’s now review the first I posted on July 27, which was after just one start and through July 25. Did these pitchers sustain their newfound velocity levels or were they one game wonders, regressing right back to 2019 marks?

Pitchers Who Were Hitting Their Stride

With only a two month season, it makes sense to look into pitchers who were gaining momentum in the final month. Of course, taking a small sample isn’t always ideal but perhaps a pitcher started to gain velocity, made a pitch mix change, or were just plain unlucky in the first month. These tangible changes could mean something and could hint at who will carry their success over into 2021.

Here are the top 30 ERA leaders in the last month:

Five Starting Pitchers to Buy Cheap — A Review

The season has ended (boy was that quick!), which means it’s now time for me to go review crazy. I like to look back at all the articles I posted proclaiming this and speculating that about the upcoming season and reviewing the players discussed and my thoughts. In mid-July, a week before the season began, I published Five Starting Pitchers to Buy Cheap. Over a shortened season, I posited that the already volatile ratio categories were going to end up at surprising levels for many starting pitchers. So perhaps it might be prudent to focus more on strikeouts and almost entirely ignore ratio projections since 12 or so starts isn’t nearly enough of a sample for ratios to settle where we expect them to. That was the basis of this post, and of course taking ADP into account and targeting cheapies.

2021 First Run Starting Pitcher Rankings

Well, we got a season! It was only two months so it’s really hard to know exactly how much stock to put it into any of it, but here’s my first look. Obviously this is subject to change and will do so quite a bit as the offseason moves forward, but I feel pretty good about this initial look. I decided not to tier it yet as I’m just not feeling confident in the cutoffs, but rest assured that there are several globs once we get past the first 25 or so. I also just labeled pitchers with their current team, we’ll get into free agent stuff later in the offseason.

Let me know what you think in the comments! I’ll have more detailed ranks out shortly after the playoffs.

Note: Pearson, Richards, and Fiers added after initial post. Meanwhile, I had missed Hudson’s TJ.

Kyle Hendricks and Location-Based Contact Management

This month last year, Connor Kurcon of Six Man Rotation set out to quantify the location aspect of command (or “LRP”). By establishing an accounting system that credited and debited pitchers for changes in ball-strike counts based on the attack zone of and hitter’s disposition (take? swing? ball in play?) for every pitch, he effectively created an alternative to Pitch Value (PVal) that rewards optimal movement through ball-strike counts but with much more pitcher and hitter context.

His findings are as you’d expect: Jacob deGrom and Justin Verlander lead the pack, with Gerrit Cole, Max Scherzer, and Clayton Kershaw not far behind. Other budding aces like Jack Flaherty and Mike Clevinger pepper the list, and some pleasant surprises (such as Brendan McKay, Caleb Smith, and, for those still thirsting, Jake Odorizzi) are scattered throughout as well. Out of the bullpen, newly anointed relief ace Nick Anderson led the pack followed by the underrated Emilio Pagán, breakout reliever Giovanny Gallegos, and others.

Near the end of his post, Kurcon includes a subhead dedicated to Kyle Hendricks where he highlights how Hendricks, widely respected as a command artist, fares lukewarmly by measure of LRP. He then reminds us “LRP doesn’t paint the full picture of command.” True that.

Fortunately, Kurcon has left the door open for me to tie up loose ends with find Gs I’ve been meaning to write up for a couple of months now. Never fear, Hendricks is the command artist we know and love — it’s just that he relies heavily on incurring contact in optimal pitch locations. It is a needle very few pitchers can thread, but Hendricks does it masterfully.
