Statcast xStats: Using Sabermetrics for 2023 Fantasy Baseball

Statcast is a valuable tool for fantasy baseball analysis, and it can be easy to look at a stat called "Expected Batting Average" and blindly use it as your projection moving forward. Of course, proper use of these metrics is a little bit more nuanced than that. First, a disclaimer: This article is about the […]

Statcast Pitch Tracking: Using Sabermetrics for 2023 Fantasy Baseball

When you're evaluating a pitcher by Pitch Info on FanGraphs, sometimes you see pitches that don't seem to accomplish anything. If Pitch X is seldom a strike, rarely chased outside of the zone, and not generating whiffs or a favorable batted line against, why doesn't the pitcher scrap it entirely? Some pitchers could improve by […]

Spin Rate: Using Sabermetrics for 2023 Fantasy Baseball

Spin rate has become one of the most recognizable Statcast metrics, with supporters of a given pitcher highlighting his spin rates to make their case. It has also become controversial due to allegations of pitchers using foreign substances to increase their spin. Unfortunately, the baseball world has done a lousy job of conveying what spin […]

Pitcher Statcast: Using Sabermetrics for 2023 Fantasy Baseball

Statcast metrics such as Barrels and Brls/BBE are great ways to evaluate a fantasy baseball batter's performance, so it is only natural to assume that the metrics would be predictive for pitchers as well. As much as batters want to hit a Barrel every time, pitchers want to avoid them at all costs. Yet, there […]

Who Is the #1 Pick for 2023 Fantasy Baseball Drafts?

The No. 1 overall pick. One of the most coveted spots in fantasy sports. If you’re one of the few lucky ones to receive a number one pick, you know how stressful it can be, however. Your pick is scrutinized by the rest of your league mates and that makes it more fun, or worrisome. […]

Barrels and Brls/BBE: Using Sabermetrics for 2023 Fantasy Baseball

Previously, we looked at how the exit velocity is only one piece of the fantasy baseball analysis puzzle. Baseball broadcasts will commonly cite Launch Angle (LA) to complement their EV figures, but it is given in terms of degrees. LA is basically a fancy way of saying things that the fantasy community has used for […]

Second Base Draft Values for Fantasy Baseball - EDV Finds Undervalued, Overvalued Picks

And we're back to the Expected Draft Values (EDV) series, where we look at historical data to identify both over and undervalued players of all types. Whether you're targeting power, speed, power+speed, batting average+power, and so on, we've got you covered. We started with first base and now head to second base as we make […]

Statcast Exit Velocity: Using Sabermetrics for 2023 Fantasy Baseball

If you've watched a baseball broadcast in the Statcast Era, you have undoubtedly noticed the broadcasters commenting on a batted ball's exit velocity, or EV. Many have taken to using stats like Hard% and Soft% to forecast how a player should be performing, expecting larger Hard% rates to produce larger BABIP and HR/FB figures. There […]

How To Play Fantasy Baseball (Roto) Rotisserie Leagues (Overview)

With the NFL blowing the season's final whistle this weekend with Super Bowl Sunday, the fantasy world is going to turn its attention to fantasy baseball. Have you ever wondered what a roto league is and how to play in it? If you've never played before, it can be very intimidating to just jump in. […]

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 […]

Where Are The Stats? In Which Rounds to Target Hitter Stats for Fantasy Baseball

If you're drafting a fantasy baseball team in a rotisserie-style league, how you attack the different categories is almost just as important as what players you draft. There are five standard categories: Runs Home Runs RBI Stolen Bases Batting Average You can put together a team that laps the field in home runs but still […]

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 […]

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 […]

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 […]
