Automated Surge and Slump Detection with Rolling Charts

This season I went add/drop crazy. I made 344 moves (adds/drops/trades). The next highest person in my league made 167. There were times when it was so incredibly uncomfortable to drop a quality player, releasing him to the waiver wire. When sharks are circling the boat, it’s not a good time to take a dip. However, as I’ve mentioned many times before, one of the leagues I care most about is a shallow 10-team, 5×5 roto league where turning and burning is almost a requirement, and turn and burn I did!

All season I was looking for indicators that would predict small clumps of player performance. xwOBA did a tremendous job of evaluating in-season talent. But, this offseason I will be looking for more ways to catch those small clusters of player performance that seem to elude me. When MLB The Show releases its monthly awards I’m usually like, “What? Really? How did I miss that?” To be fair, those players were usually rostered during that time, but it’s the ones that sneak onto the list that I’m trying to create a system for.

Finding Arozarena

You remember sorting baseball cards, right? You sorted them on anything; career stats, teams, season, jersey color. You got your sticky fingers all over those glossy, fresh pieces of thin cardboard and you just sorted away. Let’s think of a clustering algorithm called k-means clustering as that 8-year-old card sorter, only with a set of instructions. “Hey kid, here’s a bunch of cards from the last month of the season, back in 2020. Rather than your typical stat-lines, these cards show each player’s change in batted-ball and plate discipline from the first half of the month to the second half of the month. Here, take a look at Randy Arozarena”:

Guessing (Not Predicting) the Relievers Likely to Pick Up A Win

If you go to our 2021 Leaderboards, look at team relief pitcher stats, and sort by wins, you’ll see an interesting top five. The Rays, as you might have guessed, are holding the one spot by 10 wins at 56. They are followed by the Giants (46 wins), the Yankees (45 wins), and the Mets and Brewers (tied with 44 wins). If you’re like me and you’ve given up on your pitching ratios long, long ago, but are still fighting to win your league, you need wins and saves. Strikeouts are also welcome, too.

Replacement Player Analysis Using Adds & Drops

In most weekly leagues, the ability to add and drop players is gone for this season. Since there are no more moves, I’m going to analyze the most added and dropped players in NFBC’s Main Event and Online Championship with the main goal to create a composite replacement-level player.

For reference, the Online Championship (OC) leagues have 12 teams while the Main Event (ME) has 15. Both of the leagues require 23 starters each week with 7 bench spots (no IL spots). At all times, 360 players will be rostered in an Online league and 450 in a Main Event league. The reason I decided on the two NFBC formats were:

  • The data is freely available.
  • The information is from several leagues (43 Main Events, 199 Online Championships) with the same ruleset.
  • The leagues remain competitive longer since there is decent money on the line.
  • With two formats (12-team and 15-team), a comparison can be done on the different player pools.

I know at times we may seem a little NFBC centric here at Rotographs. Now, if some other platform had the ability to select a league type and make available all the adds and drops, I’d use them. The NFBC is the only platform that offers this service. Read the rest of this entry »


Probabilistic Standings Simulations – Mixed Auction LABR

Introduction

Well, we are down to the final week of fantasy baseball. After a short 60 game season in 2020, we are blessed to be approaching game 162 here in 2021!

We here at RotoGraphs, are hoping that you are right in the thick of the competition for your league’s fantasy championship title. For me – I am right in the middle of an intense battle with one of the legends of rotisserie baseball, Ron Shandler, as well as our own Jeff Zimmerman.

The league that I am referring to is the Mixed Auction LABR league. I was one this division of LABR’s inaugural members back in 2020.

Above is a photograph of some of the participants of the live 2020 auction draft from Tampa, Florida. Due to COVID, this year’s draft was held online. LABR is one of the longest running (if not THE longest currently running) expert leagues of rotisserie baseball. It is an honor simply to be invited to compete.

The Mixed auction LABR league is a very standard 12-team 5×5 rotisserie league. We use the standard scoring categories (R, RBI, HR, SB, BA, W, K, SV, ERA, WHIP), and standard rosters (14 B, 9 P). Scoring periods are weekly, trading is allowed, and the initial draft is of the auction variety. Last year, I went into great detail recapping my draft – a two-part article that can be found here and here.

As many of you might already know, as a risk management actuary – my day job consists of running simulation models to recommend purchasing decisions to the upper management of my company. I simulate possible fires, hurricanes, medical malpractice claims, and other liabilities that we may be on the hook for.

Borrowing several actuarial methods, I adapted some of these models in order to develop a proprietary in-season fantasy baseball tool. It is a probabilistic final standings simulator. Using the current league accumulated standings, a source of projected ROS statistics, a volatility and a correlation model – I run 4000 iterations of what might happen for the remainder of the season.

Do You Need Runs? Do You Want RBI?! You Need Home Runs!

Back in April, I conducted an analysis that looked at which category made the most sense to punt in roto-category scoring leagues. The results proved (somewhat) the offensive category most conducive to that strategy is stolen bases. That’s easy.

But you punted already. The punting is done. That ball ain’t coming back. Now you need to win, win, win! Therefore, you need home runs. When taking the last 15 games of the season from qualified hitters from 2015 to 2019, and limiting the dataset to just the three categories: home runs, runs, and RBI, I get the following correlations:

End of Season Correlation Sums
HR R RBI
HR 1.00 0.48 0.69
R 0.48 1.00 0.45
RBI 0.69 0.45 1.00
SUM 2.18 1.94 2.15
Among qualified hitters in their last 15 games, 2015-2019.

Homeruns, late in the season, have the highest sum of correlation. When batters hit home runs in small samples, they’re bringing runners in and scoring runs themselves. No duh. Here are three players that are projected (as of 9/20/21) to hit three more home runs according to our Depth Charts Rest of Season Projections. Now, I know you deep-league players are going to scoff and turn your nose up at these players who have not been available since your draft, but let’s give some love to the churn and burn, shallow leaguers, trying to squeeze out a few more category tens. 

C.J. Cron, Depth Charts ROS: 3 HR, 8 RBI, 6 R. ESPN Roster %: 70.9. 

Mike Podhorzer’s recent article encourages you to stack up on Rockies hitters for good reason. Pod did not include Cron because he assumed he would be gobbled up by your league mates already. But he recently went 0-for-11 before a two-hit night in Washington followed by another 0-for-3 night. There are surely managers out there that have dropped Cron and are unaware of the fact that he will be hitting in Colorado for nine games, as pointed out by Podhorzer. At home, Cron has batted .315 and on the road, has batted .226. While he is slumping as of late, his second-half .283 average is improved from his first-half .254 and his ROS projections could add a few more needed digits to your totals. 

Miguel Sanó, Depth Charts ROS: 3 HR, 7 RBI, 6 R. ESPN Roster %: 50.2.

Sano is one of those players, like Cron, that you may just be able to pick up on the wire because other managers have lost faith. But, recently Sano has been on a tear going 6-for-21 with two home runs, four RBI, and five runs. What is there left to say about Sano? He ranks 11th in savant’s Brls/PA% and fourth in average exit velocity. He’s going to hit the ball hard and hopefully, he puts it over the fence three more times as projected. Luckily, you can grab him on a hot streak and, hopefully, won’t have to suffer through too many hitless games the rest of the way. 

Tyler O’Neill, Depth Charts ROS: 3 HR, 7 RBI, 7 R. ESPN Roster %: 71.8.

This season I have fallen in love with xwOBA and its in-season predictive power. Tyler O’Neill ranks 16th in xwOBA among minimum balls in play qualified hitters. His teammate Paul Goldschmidt is just above him at 15th and since August 15th the Cardinals rank 9th in wOBA. With an offense clicking, a man that looks like he could hit a ball to Greenland, and projections to further the narrative, O’Neill should be rostered on your team the rest of the way.
