Using Sabermetrics For Fantasy Baseball Part 16 - Interpreting Minor League Stats

Using Sabermetrics For Fantasy Baseball Part 15 - Ballpark Factors

If you have ever selected a streamable pitcher based on 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. Today,... Read More

Using Sabermetrics for Fantasy Baseball Part 14 - Statcast Expected Stats

Statcast is a valuable tool for fantasy 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. Our series on how to make sabermetrics more accessible... Read More

Using Sabermetrics for Fantasy Baseball Part 13 - Statcast for Pitchers

Previously, we looked at Barrels, a stat combining exit velocity and launch angle to measure how often a batter makes quality hard contact. As much as batters want to hit a Barrel every time, pitchers want to avoid them at all costs. Yet there is some evidence that pitchers do not have the same influence... Read More

Five Hitters Whose Barrels Rate Makes Them Undervalued

Baseball is back! The nostalgic diamond traditions of cracker jacks, oat sodas and intricately-designed grass patterns have finally returned. Most importantly, the boys of summer are once again fine-tuning their five tools for the upcoming season. In 2016, Major League Baseball expanded its research on exit velocity and launch angle by introducing Barrels. Barrels not... Read More

Using Sabermetrics for Fantasy Baseball Part 12 - Spin Rate

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. Unfortunately, the baseball world has done a lousy job conveying what spin rate really means. The result has been a ton of owners who know that spin rate exists, but... Read More

Using Sabermetrics for Fantasy Baseball Part 11 - Pitch Info

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 different data... Read More

Using Sabermetrics for Fantasy Baseball Part 10 - Pitcher Batted Ball Distribution

The league average batted ball distribution in 2018 was 21.5% liners, 43.2% grounders and 35.4% flies. We have previously seen how pitchers may specialize in either grounders or fly balls. Fly ball pitchers have a BABIP advantage over their ground ball-inducing counterparts, since fly balls (.117 BABIP in 2018) consistently have lower BABIPs than worm... Read More

Using Sabermetrics For Fantasy Baseball Part 9 - Pitcher BABIP

While FIP is a useful tool to predict a pitcher's future ERA performance, fantasy owners should remember that ERA, not FIP, is what really 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... Read More

Using Sabermetrics For Fantasy Baseball Part 8 - FIP and xFIP

The first advanced pitching stat most fantasy owners 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 cast. According to the DIPS theory that the metric is based upon, pitchers control only Ks, BBs (and HBP) and home... Read More

Using Sabermetrics For Fantasy Baseball Part 7 - Lineup Spot

To this point, this series has focused exclusively on trying to predict and validate home runs and batting average. There is a reason for this--modern sabermetrics tend to 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... Read More

Using Sabermetrics For Fantasy Baseball Part 6 - Pull Percentage

Earlier in this series, we saw that fantasy owners generally prefer batters to hit the ball into the air in order 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... Read More

Using Sabermetrics For Fantasy Baseball Part 5 - Plate Discipline

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 owners have known for years that players like Chris Davis are potential drains on a fantasy team's batting average. Furthermore, players that whiff a lot tend to continue...

Using Sabermetrics For Fantasy Baseball Part 4 - Batted Ball Distribution (Hitters)

Fly balls can turn into home runs. Ground balls never do. It would seem as though fantasy owners want their batters to hit nothing but flies, yet this is not the case. Why would this be? The answer, of course, comes down to batted ball distribution and the manner in which batters make contact. In... Read More

Using Sabermetrics For Fantasy Baseball Part 3 - Statcast for Hitters

If you've watched a baseball broadcast in the so-called 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.... Read More

Using Sabermetrics For Fantasy Baseball Part 2 - HR/FB for Hitters

Using BABIP to predict a player's batting average is great. Average is a category in many league formats, and every hit is an opportunity to steal a base or score a run. But most owners find the long ball sexier. Every HR comes with a guaranteed run scored and at least one RBI. Many owners... Read More
