As the 2023 Major League Baseball World Series has now concluded, I would like to share several takeaways that stand out to me from the fantasy baseball season. Some of these points will be a data-driven look at 2023 trends or anomalies. Some of these topics will help shape some fantasy draft strategy in 2024. […]

New MLB Rule Changes - How Fantasy Baseball Experts are Handling their 2023 Projections

Earlier this September, Commissioner of Baseball Robert D. Manfred Jr. announced a number of rule changes that Major League Baseball would begin to employ starting in 2023. The rule changes addressed a few general areas of the game of baseball from the pace of play – to the physical dimensions of the field – to […]


Early Plate Discipline Standouts for 2022

In 2019, I introduced a new (yet simple) index statistic for pitchers – mPDI, which was inspired by a famous quote by Hall of Fame pitcher, Greg Maddux: “The key to pitching is to have the ability to throw a strike when they’re taking and throw a ball when the hitter is swinging.” Maddux’s simplistic […]

In my previous article, “Identifying Risk via the ATC Projections – Round 1,” I provided a primer on the ATC Projections volatility metrics. To further your understanding, and for a visual explanation of how these volatility metrics work, please check out the seven-minute video entitled, “Using ATC Projections to Minimize Fantasy Baseball Draft Risk.” This […]

Today’s article will attempt to give the reader a few new perspectives on player risk. I will attempt to enhance your understanding of projections, and at the same time seek to form a more complete picture of each player. To do this, I will first color in your understanding of the makeup of the ATC […]

Five Undervalued Standout Pitchers - Maddux Plate Discipline

“The key to pitching is to have the ability to throw a strike when they’re taking and throw a ball when the hitter is swinging.” - Greg Maddux Using my weighted plate discipline index statistic - the Maddux Plate Discipline Index (mPDI) - we can enumerate the percentage of time in which pitchers demonstrate the […]


Early Plate Discipline Standouts

In 2019, I introduced a new (yet simple) statistical metric which focuses on the core ingredients of plate discipline. The Weighted Plate Discipline Index (wPDI) looks at the following basic binary events: Was the ball thrown in the zone? Was the ball swung on? Did the batter make contact with the ball? Weighted Plate Discipline […]


The Mathematics of Fantasy Baseball: An Injured Fernando Tatis

The start of the 2021 Major League Baseball season has arrived notwithstanding adversity. The entire Mets versus Nationals series was postponed due to a number of players who tested positive for COVID-19. Prior to the season’s start, there were a number of talented major leaguers who succumbed to injury. Eloy Jimenez and Adalberto Mondesi were […]

ATC Projections Volatility for Multi-Category Players

One year ago, I penned my very first article on RotoBaller. I am truly honored that the Fantasy Sports Writers Association (FSWA) awarded the piece as the 2020 Baseball Article of the Year. “Finding Combo-Player Values Using Z-Scores and ATC Projections” provided a new perspective on how to find helpful multi-category players to fill out […]


How I Won Tout Wars

I am extremely fortunate to be able to write an article entitled, “How I Won Tout Wars.” It is truly a humbling experience, and I am both excited and proud to pen today’s words. Including all of the draft preparation that I describe in my aforementioned articles, here a few of the reasons that (I […]


2020 wRC+ Splits: Risers and Fallers

Baseball in 2020 is unlike any season that I can remember. The designated hitter is now present in the National League. You will not find any more LOOGYs with the institution of the three-batter minimum rule. Doubleheaders are now a combined 14 innings of baseball. Extra innings now start with a runner on second base. […]


Greg Maddux Plate Discipline Standouts for 2020

In my previous article, I wrote about my new weighted index statistic for hitters – mPDI, which stems from a famous quote by Hall of Fame pitcher, Greg Maddux: “The key to pitching is to have the ability to throw a strike when they’re taking and throw a ball when the hitter is swinging.” The […]


Plate Discipline Standouts for 2020

Last year, I unveiled a new weighted index statistic for hitters – mPDI, which mirrors a famous quote by Hall of Fame pitcher, Greg Maddux: “The key to pitching is to have the ability to throw a strike when they’re taking and throw a ball when the hitter is swinging.” If we consider the inverse […]


Ariel Cohen's 2020 MLB Awards Predictions

Baseball is back! Opening day is finally upon us. We can now finally log in to our fantasy leagues and observe as the statistics start to accumulate. What a great feeling! We had to wait a few months longer this year due to the tragic global pandemic of COVID-19, but we are finally here. I […]


Attacking Offensive Categories with Z-Scores

The way to win at fantasy baseball is to generate the most aggregate value on your roster. One cannot win with just an average fantasy team; one must be better than the mean. To accomplish this, owners must spend their fantasy capital efficiently in acquiring talent. Finding and drafting undervalued players is the key. Of […]

Adjusting Fantasy Baseball Projections for a Delayed Opening Day

With a heavy heart I write this column. I truly wish that there would have not been a reason to write this column. Coronavirus (COVID-19) has now postponed the 2020 Major League Baseball season. In an effort to employ social distancing, local governments have made the tough call to forbid the gathering of large crowds. […]


Finding Combo-Player Values Using Z-Scores and ATC Projections

Towards the end of last season, I asked the question – “Draft Speed or Pound the Power?” Loaded in this seemingly simple query are two contradictory approaches – one for power and one for speed. Power Approach 1: Home run totals are dramatically up in baseball these days. Therefore, there are many power bats available […]
