Ballpark Factors: Using Sabermetrics for 2023 Fantasy Baseball

If you have ever selected a streamable pitcher based on a home park or benched an otherwise must-start arm at Coors Field, you already know how much a stadium can impact a player's bottom line. Ballpark Factors quantify the influence each stadium has, allowing you to make the most of your fantasy team's real-life schedule. […]

Pitch Info: Using Sabermetrics for 2023 Fantasy Baseball

One of the most fundamental questions in fantasy sports is if a player's current performance is sustainable. More than any other sport, baseball has a slew of statistical measures that can be dissected in numerous ways to analyze player performance. Pitch Info is a publicly-available pitch tracking system that provides a lot of data to help […]

Lineup Slots: Using Sabermetrics for 2023 Fantasy Baseball

You may be wondering why there aren't any advanced stats aimed at predicting a player's counting stats like runs and RBI. The answer is simple: modern sabermetrics reject the idea of a "clutch RBI guy" and therefore do not bother inventing predictive metrics for it. Runs and RBI are team-dependent stats and are unhelpful in ascertaining […]

Pull%: Using Sabermetrics for 2023 Fantasy Baseball

We have previously determined that fantasy managers generally prefer batters to hit the ball into the air to have a chance at a home run. Yet, all fly balls are not equal for this purpose. A player can maximize his power production by pulling the ball in the air. One way to illustrate this is […]

Pitcher BABIP: Using Sabermetrics for 2023 Fantasy Baseball

While FIP is a useful tool to predict a pitcher's future ERA performance, fantasy managers should remember that ERA, not FIP, is what matters in most formats. This means that we are interested in the "luck" that separates the two statistics. While some of this luck is unpredictable, we can and should predict some of […]

FIP/xFIP: Using Sabermetrics for 2023 Fantasy Baseball

While we've only examined how to evaluate hitters using advanced stats thus far, sabermetrics are at least as useful for pitchers. The first advanced pitching stat most fantasy managers encounter is FIP. FIP stands for Fielding Independent Pitching and attempts to measure a pitcher's actual skill instead of the effects of luck or his supporting […]

Plate Discipline: Using Sabermetrics for 2023 Fantasy Baseball

No matter how high a particular player's BABIP may be, his average will be mediocre at best if he strikes out too much. This is why fantasy managers have known for years that players like Mike Zunino are potential drains on a fantasy team's batting average. Furthermore, players who whiff a lot tend to continue […]

Batted Ball Distribution: Using Sabermetrics for 2023 Fantasy Baseball

Fly balls can turn into home runs. Ground balls never do. It would seem as though fantasy baseball owners want their batters to hit nothing but flies, yet this is not always the case. Why would this be? The answer, of course, comes down to batted ball distribution and how batters make contact. The league […]

HR/FB: Using Sabermetrics for 2023 Fantasy Baseball

Using BABIP to predict a player's batting average is great. Batting average is a category in many league formats, and every hit is an opportunity to steal a base or score a run. Most fantasy managers find the long ball sexier, though. Every HR comes with a guaranteed run scored and at least one RBI. […]

Hitter BABIP: Using Sabermetrics for 2023 Fantasy Baseball

The most accessible of the fantasy-relevant advanced stats is BABIP, or Batting Average on Balls In Play. It simply measures a player's batting average on balls in play, with outcomes such as strikeouts and home runs removed from consideration. In general, the league average hovers around .300, a nice round number to remember. However, it […]

Using Sabermetrics for 2023 Fantasy Baseball: Introduction

Hello, fellow RotoBallers! Sabermetrics have become an integral tool for fantasy baseball draft prep, but a concise resource for understanding the basics can be difficult to find. This series will attempt to define and explain all of the metrics fantasy managers may find useful, citing examples of how to use them in the process. Multiple […]

Cal Raleigh: Champ or Chump for Fantasy Baseball?

Did you know that catcher Cal Raleigh has hit 25 homers for the Seattle Mariners this season? Drafted in the third round of the 2018 amateur draft, Raleigh once had some prospect pedigree but saw it fade when his MiLB numbers weren't special. He made his big league debut in 2021 and hit .180/.223/.309 with […]

Josh Jung: Champ or Chump for Fantasy Baseball?

We've reached the middle of September, which means that many fantasy managers are either completely out of it or cruising to a title. If you're among the few in a battle that will last until the season's final days, the particulars of your league standing page will dictate what you have to do. Therefore, the […]

Triston Casas: Champ or Chump for Fantasy Baseball?

September call-ups might not be as extensive as they once were, but that hasn't stopped a variety of prospects from being called up in the past few days. The latest debut is first baseman Triston Casas of the Boston Red Sox, a name that Boston fans have been screaming for since Bobby Dalbec proved he […]

Corbin Carroll: Champ or Chump for Fantasy Baseball?

With September on the horizon, fantasy managers have officially entered the stretch run. This is the time of year when your standings page should be dictating the moves you're making, as it often makes sense to drop a more talented player for one who contributes in key areas you can gain points. Your rivals are […]

Brett Baty: Champ or Chump for Fantasy Baseball?

The Braves (and fantasy managers) are enjoying the production of Vaughn Grissom following injuries to Ozzie Albies and Orlando Arcia, so the Mets decided to try the same trick by promoting top prospect Brett Baty in the wake of injuries to Eduardo Escobar and Luis Guillorme. Like Grissom, Baty has relatively little experience in the […]

Vaughn Grissom: Champ or Chump for Fantasy Baseball

When it comes to prospects, there are two camps that fantasy managers can fall into. Some have severe FOMO and attempt to roster every player called up with even a moderate pedigree, often wasting roster spots that could have been better used on older breakout players or consistent veterans. Others need a reason to roster […]

Andrew Benintendi: Champ or Chump for Fantasy Baseball?

Now that all of the real baseball trades are in the books, it's time to assess who won and who lost. In this author's estimation, the Mariners won by acquiring the big pitcher they needed in Luis Castillo, hopefully ending the longest postseason drought in North American sports. The Padres are being credited as a […]

Tyler Anderson: Champ or Chump for Fantasy Baseball?

With the MLB trade deadline rapidly approaching, fantasy managers are also under the gun to make the last-minute moves that will set them up for a successful stretch run. Everybody says that you should "buy low" and "sell high," but your rivals are likely to follow the same philosophy. The trick, therefore, becomes letting a […]

Oneil Cruz: Champ or Chump for Fantasy Baseball?

Plenty of top-rated prospects have debuted in recent years, but very few have offered the raw tools of Oneil Cruz. Cruz is the tallest man to ever start an MLB game at shortstop and set a record for hardest infield throw in his first game of the season. Scouts believe he'll stick at short for […]

Leody Taveras: Champ or Chump for Fantasy Baseball?

With the All-Star Break upon us, now is a great time to look at your league's standings page and formulate a plan of attack for the rest of the season. If you're in first, try to proactively identify and address any weaknesses that could be exploited by your rivals. If you're in contention, identify where […]

Ramon Laureano: Champ or Chump for Fantasy Baseball?

Fantasy managers knew that Ramon Laureano would miss the first 27 games of the 2022 season due to his 2021 PED suspension, but he was still seen as a solid late-round pick for the category juice he provides. In 2019, he slashed .288/.340/.521 with 24 homers and 13 steals over just 481 PAs. That regressed […]

Jonathan Villar: Champ or Chump for Fantasy Baseball?

Every fantasy manager has a weakness for a particular player or even player type. Perhaps you've rostered Nomar Mazara for the last five years because you just know that breakout is coming. Maybe you always spend a draft pick on Eduardo Rodriguez because this is the year he finally pitches up to his peripherals. You […]

Jeremy Pena: Champ or Chump for Fantasy Baseball?

Jeremy Pena was one of the biggest stories of the offseason. The contending Astros expressed minimal interest in retaining the services of star shortstop Carlos Correa and even less in the countless other names available at the position, instead anointing the 24-year-old Pena as their shortstop of the present and future. Pena's role in a […]

Riley Greene: Champ or Chump for Fantasy Baseball?

The big-time prospects keep coming up from the minor leagues with 21-year-old Riley Greene surfacing for the Detroit Tigers. Greene was originally slated to break camp with the club but a broken right foot in Spring Training delayed his debut. Still, he singled in his first PA and currently has a BB% above 40 at […]

Gabriel Moreno: Champ or Chump for Fantasy Baseball?

When a consensus top-10 prospect is summoned to the major league level, the fantasy community always takes notice. As such, many were scrambling to the waiver wire once the Toronto Blue Jays announced that Gabriel Moreno was being called up to replace the injured Danny Jansen on their roster. To say that Moreno is a […]

Christopher Morel: Champ or Chump for Fantasy Baseball?

There's always a flavor of the week in fantasy baseball, some of whom have staying power while others are banished to the waiver wire never to be heard from again. If you play in a keeper league or a shallow format, the trick is identifying which camp a particular player belongs to so you know […]

Anthony Santander: Champ or Chump for Fantasy Baseball?

The fantasy baseball community has a nasty habit of ignoring players who don't play for the best teams, especially if they lose whatever might have made them appealing. For example, the Baltimore Orioles have been terrible for a while now and their hitters were rostered only because Camden Yards was a good ballpark for power. […]

Roansy Contreras: Champ or Chump for Fantasy Baseball

The next big prospect in fantasy land comes by way of Pittsburgh, as the Pirates are summoning 22-year-old Roansy Contreras to join their rotation. He has already logged MLB time this season with a 3.52 ERA and 10 punchouts over 7 2/3 IP of relief work, but the role wasn't conducive to fantasy value. He […]

Gleyber Torres: Fantasy Baseball Champ or Chump?

Isn't it amazing how one strong fantasy season can keep a player on our radars for years? Gleyber Torres was fantastic in 2019, slashing .278/.337/.535 with 38 long balls. He was widely cited as a potential bust the next year given middling Statcast metrics and the fact that half of his production came against the […]
