Champ or Chump: Sammy Long

With news breaking that Wander Franco would make his much-anticipated big league debut tonight, we're reminded what fantasy managers look for in a rookie. We want advanced physical tools, including power and speed for hitters and sexy velocity and spin rate numbers for pitchers. We look for strong MiLB performances as well. We want guys […]

Champ or Chump: Alec Bohm

A lot of huge names are underperforming in 2021, including DJ LeMahieu, Mookie Betts, Francisco Lindor, Freddie Freeman, and Trevor Story. Alec Bohm isn't the same type of household name those guys are, so the fact that he's only slashing .224/.266/.309 on the season with four homers and three steals after a breakout debut in […]

Champ or Chump: Cedric Mullins

Cedric Mullins is probably one of the biggest fantasy surprises of the year. The 26-year-old was virtually unheard of heading into 2021, though he logged MLB PAs in each season since 2018. Toiling in Baltimore can make it easy to get overlooked, especially if you're posting mediocre numbers with worse peripherals. Mullins gave up switch-hitting […]

Champ or Chump: Jarred Kelenic

Jarred Kelenic was one of the hottest prospect names coming into the 2021 fantasy baseball draft season. A since-fired executive blatantly admitted that the 21-year-old was ready for the Show last season but that the team didn't call him up for service time reasons, leading some managers to feel that the Mariners would carry him […]

Champ or Chump: Adolis Garcia

Fantasy managers generally look for certain qualities when evaluating prospects. We like younger players who post dominant numbers on the farm. We like prospects with raw tools that make scouts salivate, leading to appearances on top prospect lists. We like players who we had heard of before the season started. Adolis Garcia checks none of […]

Champ or Chump: Huascar Ynoa

Is your fantasy team looking for more pitching? Nearly every manager is, making it difficult to find breakout arms on the waiver wire since everybody is looking for the same thing. This situation can also make it far too easy to put more faith in a breakout performance than warranted, potentially leaving you with an […]

Champ or Chump: Dominic Smith

Evaluating 2020 fantasy seasons has been very difficult. Each player's season line looks like a full campaign on a player's FanGraphs page or the back of their baseball card, but in truth, it's only slightly more than one-third of a full season. There had to be some legitimate breakouts that we shouldn't discount, but how […]

Champ or Chump: Luis Castillo

Nothing is worse for a fantasy manager than when an early-round pick puts up disastrous numbers. You can't start the guy because he's brutalizing your ratios, yet you can't drop him because you've invested too many resources to give him up for free. What if he turns it around in his next appearance and you […]

Champ or Chump: Buster Posey

Some things about fantasy baseball change every season, while others are consistent from year to year. For example, breakout relievers exist every year but their names are different from season to season. You never want to use your first-round pick on a dud, but early-round duds have different reasons each year. If you played fantasy […]

Champ or Chump: Zach McKinstry

It seems like the young MLB season isn't producing as many random breakout stars as it usually does. Tyler Naquin had one huge game, but he isn't even playing every day. Akil Baddoo is a nice story for Detroit, but his OBP is below .300 and he's in a platoon. Where is Keven Maas when […]

Champ or Chump: Jonathan India

The NL Central was among the most wide-open divisions in all of baseball coming into the season. The Milwaukee Brewers were the favorites if you believe the projected standings at FanGraphs and Baseball Prospectus, but oddsmakers tended to favor the St. Louis Cardinals after their splashy addition of Nolan Arenado. The Cubs still had their […]

Champ or Chump: Tyler O'Neill

With Opening Day officially in the books (for most teams anyway), the 2021 campaign is off and running. The secret to being a successful fantasy manager is to combine a strong draft with superlative in-season roster management. Early in the year, your focus should be on identifying potential 2021 breakouts that your rivals may not […]

Using Sabermetrics for Fantasy Baseball: Statcast xStats

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. First, a disclaimer: This article is about the "Expected […]

Using Sabermetrics for Fantasy Baseball: Pitcher Statcast

Statcast metrics such as Barrels and Brls/BBE are great ways to evaluate a 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 is evidence […]

Using Sabermetrics for Fantasy Baseball: 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. It has also become controversial as of late due to allegations of pitchers using foreign substances to increase their spin. Unfortunately, the baseball world has done a lousy job conveying […]

Using Sabermetrics for Fantasy Baseball: Statcast Exit Velocity

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. […]

Using Sabermetrics for Fantasy Baseball: Barrels

We've previously looked at how exit velocity (or EV) is only one piece of the fantasy analysis puzzle. Baseball broadcasts will commonly cite Launch Angle (LA) to complement their EV figures, but it is given in terms of degrees. Am I evaluating a baseball player or trying to find the hypotenuse of an isosceles triangle? […]

An Introduction to Advanced Stats for Fantasy Baseball Managers

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. Over the next two months, this series will attempt to define and explain all of the metrics fantasy owners may find useful, citing examples of how to use […]

Using Sabermetrics for Fantasy Baseball: MiLB Stats

Once you've grown accustomed to having advanced tools to help make fantasy decisions, it can feel disorientating to be without them. Prospects are increasingly becoming a focal point in both real and fantasy baseball, but the minors simply do not have all of the data publically available for MLB players. For example, advanced plate discipline […]

Using Sabermetrics for Fantasy Baseball: 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. However, […]

Using Sabermetrics for Fantasy Baseball: 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 to […]

Using Sabermetrics for Fantasy Baseball: Batting Order

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 […]

Using Sabermetrics for Fantasy Baseball: Pitcher BABIP

While FIP is a useful tool to predict a pitcher's future ERA performance, fantasy managers 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 […]

Using Sabermetrics for Fantasy Baseball: Pull%

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 […]

Using Sabermetrics for Fantasy Baseball: FIP/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, pitchers control only Ks, BBs, and home runs allowed. Therefore, Ks, walks, and dingers are […]

Using Sabermetrics for Fantasy Baseball: 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 managers 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: Hitter Batted Ball Distribution

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 always the case. Why would this be? The answer, of course, comes down to batted ball distribution and how batters make contact. The league average […]

Using Sabermetrics for Fantasy Baseball: HR/FB

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. But most fantasy managers find the long ball sexier. Every HR comes with a guaranteed run scored and at least one RBI. […]

Using Sabermetrics for Fantasy Baseball: Batter BABIP

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. Many know […]

Champ or Chump: Year in Review

Now that the 2020 fantasy baseball season has come to a close, it is time to assess your performance. Did you ignore red flags that you wish you hadn't? Was a strong process foiled by unpredictable factors outside of anybody's control? Both of these things are likely true to some extent. The key is to […]
