2015 Pod Projections: Jacob deGrom

The Pod Projections are back! My projections are based on the methodology shared in my eBook Projecting X, and the process continues to evolve and improve.

Interestingly, I have seen many commenters ask for advice when choosing between this Monday’s Pod Projectionee, Carlos Carrasco, and today’s choice, Jacob deGrom. You’ll see when I unveil my full deGrom projection below, but it’s a rather close call, as they have very similar forecasts.

With that said, deGrom essentially came out of nowhere last year to post a sub-3.00 ERA in 22 starts and earn NL Rookie of the Year honors. He generally posted ho-hum minor league peripherals, but perhaps fueled by a faster slider, his coming out party occurred in the Majors. Before beginning my projection, I shared four reasons why deGrom was for real. Since I gave it away above by comparing the projection to Carrasco’s, I’ll tell you that I still feel the same way.

Steamer and I: Jose Abreu & Giancarlo Stanton

Last week, I posted the first comparison in this new series discussing discrepancies between the Steamer and Pod Projections. I began by looking at Corey Dickerson and A.J. Pollock, two players I was far more optimistic about this season than Steamer is. Today, I’ll look into a pair of sluggers who Steamer likes better than I.

Steamer doesn’t like many hitters better than I do. Of the 328 hitters we both project, Steamer projected at least .001 wOBA points higher than I did for just 83 of them (25.3%). On the other hand, I am more bullish on 232 hitters (70.7%), while we project identical wOBA marks for 13 hitters (4.0%).

2015 Pod Projections: Carlos Carrasco

The Pod Projections are back! My projections are based on the methodology shared in my eBook Projecting X, and the process continues to evolve and improve.

If there was just one thing to be thankful for last year in baseball, it was Carlos Carrasco. I had written a lot about him heading into the season and his performance upon returning to the rotation prompted more articles salivating over the quality of his stuff. So he was a rather obvious candidate to earn the honor of my first starting pitcher receiving the Pod Projection treatment.

For those who forget (how dare you!), Carrasco posted the following line over his final 10 starts of the season:

IP ERA WHIP K% BB% GB% xFIP
69.0 1.30 0.81 29.8% 4.2% 49.1% 2.16

Despite those sizzling results coming over a relatively small sample size, fantasy owners are going gaga over Carrasco. He is currently the 115th player off the board in the NFBC and is the 28th starter selected, ahead of more established veterans like Gio Gonzalez and Hyun-Jin Ryu. And no, I haven’t stuffed the ballots by joining every single NFBC league and drafting Carrasco.

Hitter Analytics (3/1/15)

Some updates

• A form has been added for people to added some times. Some players have already been submitted by some readers. Thanks to those helping.
• I have the projected strikeout and walk rates added.
• I have cleaned up the verbiage a little.
• I have 100 scale information for every hitter for each of nine batted ball categories over the past three seasons.

Note: Some people were not able to open the spreadsheet on an Apple. I tried to save the spreadsheet as a .xls, but the embed feature didn’t work. Here is a like to downloadable .xls. I am trying to figure out a solution.

 

Pitchers’ Approach Attacking Hitters

Robert Arthur at Baseball Prospectus has shown pitchers will change their approach depending on the hitter’s talent level. Here is a complete list of the number of fastballs (including sinkers) thrown to each hitter of the past two years divided into half seasons. Also the number of pitches in the strike by half season is included along with the fastball percentage in the strike zone. I will begin adding 2015 information as it becomes available.

NL OF Projections: Steamer vs. the Fans

I have never thought much about, or given much attention to, FanGraphs’ fan projections. It’s primarily a matter of stubbornness: I run my own projections, and I develop my own strategy, so why should I listen to you? At least there’s a trace of rationale behind it: I know how I created my projections (whether or not they’re any good is a topic for another day), but I have no idea how you created yours. Thus, I am more likely to blindly trust a computer-generated projection system such as Steamer instead of random fan projections.

Still, there is a sort of bizarre, secondhand wisdom to fan projections. For every person who is high on a particular player, there could be another person who is equally-and-oppositely down on him. Solicit and aggregate enough fan projections and you could produce a very reasonable prediction of a player’s performance by sheer chance.

Which is why fan projections intrigue me. If, for example, Steamer predicts the most likely outcome from a wide range of possible outcomes for a player, then the fans convey the anticipated outcome for a player. The difference between them, you could say, is what amounts to a market inefficiency (aka a price distortion). The larger the difference, the greater the inefficiency. We see these inefficiencies arise every year — 2014’s most prevalent example is probably Corey Kluber — and they typically manifest because of a lack of information about certain players.

Steamer and I: Corey Dickerson & A.J. Pollock

You know that I develop my own player projections, of which I have lovingly dubbed Pod Projections. With over 500 players projected, I thought it would be interesting to compare them with the Steamer forecasts. So Steamer and I is a new mini-series in which I discuss a pair (maybe more, maybe less) of players who I have projected for dramatically different results than Steamer. To do this, I simply compared my wOBA projections with Steamers’, calculated the difference and then sorted.

2015 Pod Projections: George Springer

The Pod Projections are back! My projections are based on the methodology shared in my eBook Projecting X, and the process continues to evolve and improve.

For Pod Projectionee numero tres, I decided to take commenter Cason Jolette’s (Jason Colette’s mysterious brother?) suggestion to discuss former uber prospect, Astros sophomore outfielder George Springer. His coming out party was cut short by a quad injury, which ended his season two months prematurely. But he was quite impressive at the plate, posting a .352 wOBA, while displaying excellent patience and elite power. But coming off a minor league performance a year prior that included 45 stolen bases, he disappointed with his speed in Houston, as he swiped just five bags in seven tries. Let’s figure out what’s in store for Springer in 2015.

Taking Hitter Analysis to Another Level

Truthfully, I have had it. Here at RotoGraphs we are almost too good at identifying emerging pitchers. We can decently find up-and-coming pitchers with Arsenal Score being the last great accomplishment. Additionally, I am also to blame by looking at how pitchers change and determining if they may be injury prone (example with Scott Kazmir). Most of the advancements in examining pitchers is because of the addition of Pitchf/x data. We know immediately if a pitcher is throwing slower or if he has a new pitch. I feel hitters have taken a back seat for a few years and I would like to try to increase our knowledge of them. I plan on expanding into new areas for batters. Also, I am completely open to new ideas from our readers.

One of the biggest issues with hitters is it tough to know if/when they have changed. The difference may involve power, foot speed, swing adjustments or how pitchers are adjusting to the hitter. I want to take hitter analysis to the next level. I will attempt to live on the “tip of the spear”. The problem with living on the tip is I will probably get cut a few times. I am going to look at some never published data and see if it is useful/predictive. I could see several of my ideas not working out.

Finally before I get into some of my ideas, I will gladly welcome any of your ideas. It can be tweak to something I bring up or a completely new idea. I am ready to give hitters their fair shake.

Yasmany Tomas’ Plate Discipline Makes Me Nervous

The baseball community — owners, scouts, fantasy analysts et al. — is slowly learning how Cuban hitters plucked from the Cuban National Series (CNS) perform in Major League Baseball. Unfortunately, the sample size is not increasing very quickly. The common fantasy owner is helplessly resigned to rely on a) scouting reports, and/or b) his or her own eyes, probably via a batting practice video uploaded online. Ideally, a Cuban hitter’s salary would serve as a proxy for what one could expect offensively and defensively from his imported bat and glove, but the market, and the information that defines it, is far from perfect.

The market for Cuban hitters is a pendulum, but rather than coming to rest, it is in full swing: hitters such as Yoenis Cespedes, Yasiel Puig and Jose Abreu, who are all but locks to fulfill the value of their modest contracts and then some, have plumped up the market for international signees. The Diamondbacks’ Yasmany Tomas, therefore, should not be compared to Abreu simply because the average annual values (AAV) of their contracts are almost identical. The dynamics of this particular market are nebulous, changing with every transaction.

But that doesn’t mean we can’t compare Tomas and Abreu statistically. Comparing the CNS and MLB performances of hitters more recently signed out of Cuba can still give us at least a faint idea of how we can expect Tomas to perform. This is my hope, at least. I’ll be the first to admit the analysis that follows is not as rigorous as I wish it could be, as the sample of contemporary, fantasy-relevant Cuban hitters who recently played in the CNS simply lacks breadth.

2015 Pod Projections: Yasmany Tomas

The Pod Projections are back! My projections are based on the methodology shared in my eBook Projecting X, and the process continues to evolve and improve.

Today’s Pod Projectionee is Cuban rookie Yasmany Tomas, who I drafted in last week’s LABR mixed league. It’s hard enough projecting Major League veterans and even more difficult forecasting rookies with only minor league data to rely on. But trying to predict exactly what a player with no professional experience in a stateside league might do is a true shot in the dark. So this was a challenge and one I would like to share with you.
