Reverse Engineering the Sharks: Intro

Gambling and baseball go way back. Everyone, casinos and betters, look to gain an edge with the hope of free money. Today, I’m starting a series diving into the lines with the hope of finding which information, fantasy or otherwise, can be extracted from the sharks and books using the FanGraphs win rate as a baseline.

To start the study, I used the game projections available here at FanGraphs and the historic Vegas line. While the FanGraphs projections were right more times than wrong, there was a systematic error I quickly found. The home-field advantage was set to 8%. The home field teams were expected to win 54% of the time and lose 46% (math!) for the 8% spread. I looked back at the league-wide home-field advantage over the past dozen season and found a smaller margin.

Fantasy & Reality: Pérez, López, Quintana & More

Today, I am going through some fantasy-relevant information which could change several player projections.

Dan Hayes of The Athletic ($$) stated the following on Martín Pérez.

The Twins believe the keys to Pérez’s great early performance this season were working with increased velocity and filling up the strike zone. For the past few weeks, Twins pitching coaches have encouraged Pérez not to worry about conserving energy in order to pitch deep into games.

Air it out. Let them worry about the late innings. And on the days when the velo isn’t there, locate and attack.

Draft Speed or Pound the Power?

Introduction

On the latest episode of The Great Fantasy Baseball Invitational Podcast, I posed the following question:

In 2020 fantasy baseball drafts for roto leagues, which will you do early on?

A) Draft Speed Early
B) Pound the Power

Simultaneously, I posed the identical question on Twitter, yielding the following results:

The Twitter responses, as well as the members of the TGFBI Beat the Shift Podcast panel were pretty evenly split on what was more important to focus on. Obviously, fantasy owners need to focus on both; players who can amass a broad base of stats are ideal. But the question is still a valid one – in a vacuum, all things being equal, which player type should you favor in a draft?

2019’s Fantasy Baseball Auction Bargains at Mid-Season – The Value Drainers

Previously, I looked at the hitter and pitcher auction bargains of 2019 at mid-season. These were the players that have earned the most rotisserie value, net of their cost to roster.

Now let’s turn our attention to the players who have lost the most profit in the first half of 2019, who I will refer to as the value drainers. These are the largest under-performers (to date), relative to their pre-season auction values.

To remind everyone:

  • $Value refers to the accumulated 5×5 rotisserie value of each player, scaled to a full-season.
  • $AAV refers to the average auction cost to purchase the player pre-season.
  • $Bargain is the difference between the $Value and the $AAV.

For this exercise – In order to calculate $Value, I use NFBC roster settings and scoring parameters. Actual $AAV data is used to determine the opportunity cost. For the full methodology of how these player bargains are calculated, please refer to my introductory post. Read the rest of this entry »


2019’s Fantasy Baseball Auction Bargains at Mid-Season – Pitchers

Last week, I looked at the 2019 auction hitter bargains at mid-season. Now let’s dive into the most profitable pitchers of the first half.

To remind everyone, we aren’t looking here for the highest earning pitchers of 2019 – we are looking at pitchers with the largest values net of their opportunity cost to acquire. Gerrit Cole has earned nearly $24 of fantasy auction value – making him the 7th highest earning pitcher. However, with his $36 average auction value – he technically is in the red as far as profitability goes.

For the methodology employed and the terms used in the ensuing leaderboards, please refer to my previous post on the 2019 Fantasy Baseball Auction Bargains at Mid-Season – Batters edition.

2019’s Fantasy Baseball Auction Bargains at Mid-Season – Batters

There are two different and distinct ways to kick off each season in fantasy baseball. I am referring to the two popular ways to fill teams’ rosters pre-season – namely snake drafts and auctions. In either method of commencement, the goal is to accumulate the most player statistics for the forthcoming season.

However, drafts differ from auctions in the value proposition of roster slots – which is static for snake drafts. Unless you are able to trade draft picks, you are cemented with those specific slots that in turn correspond to fixed levels of fantasy value. At an auction, the distribution of acquired values may vary more widely.

The predominant first overall snake draft selection in just about any fantasy format (or depth) this year was Mike Trout. The impetus for that is easy to explain. Trout is the player with a tremendous (dare I say the highest) floor of talent, a high upside of statistics to accumulate, and a proven track record to back everything up. In economic terms, he provided the most potential value with the least amount of risk.

Two-Start Rankings: What’s the Cutoff?

In last week’s “Who is Being Dropped & Why”, I noted the following on Jeremy Hellickson

At home, he faced the Mets and Cubs and they lit him up. I went back over the previous two weeks in the NFBC Main Event to see if owners targeted him for this two-step. In the Main Event, owners typically look two weeks ahead on the two-start pitchers to get a jump on the crowd.

Week: Add Count, Avg Bid
8: 7, $14
9: 5, $5

First, I found it a little funny that the owners hoped to get a jump on the bidding paid more. Second, almost all of the Hellickson shares added were then dropped (12 of 13).

Is Chris Archer Rosterable?

Introduction

I made the following controversial proclamation earlier this year – that Chris Archer is highly overvalued by fantasy owners. I go even further to say that in all but deep mixed leagues and mono leagues – continually rostering the right hander would be a poor use of fantasy resources.

My contention with Archer’s value stems from his ratio stats:

Ariel Cohen’s 2019 Bold Predictions

Opening day is finally here!

Draft season is now ending. It is time for our fantasy teams to finally start accumulating statistics (Japan series aside). After the long winter, the excitement of a new season has finally reached its pinnacle.

Now it is time to share my 2019 bold predictions with you. The ATC Projections helped shape some of these. Others come from my own personal analysis on the player, or team situation. The rest arise from blind optimism or the crossing of my fingers. These are all possibilities that could happen, that I feel will happen if things break just right.

2019 Pod vs Steamer — ERA Downside

Yesterday, I identified and discussed 13 starting pitchers the 2019 Pod Projections forecasted a significantly lower ERA than Steamer. Today, I’ll take on the other group — those the Pod Projections are more bearish on than Steamer in ERA. I’ll only discuss those pitchers you truly care about.
