Introducing EDV - Expected Draft Values for Fantasy Baseball

Last March at RotoBaller, we kicked off a cool fantasy baseball research project, exploring what we're calling Expected Draft Values. This offseason, we’ve refined the approach and our research, and taken things a step forward. We're sharing this concept with the fantasy baseball world now, and hope it's as helpful to you as it's been... Read More

Biggest Fallers: K-BB%, Part 1

K-BB% is a valuable metric because it shows which pitchers can combine strikeout ability with pinpoint control. Pitchers with high K-BB% possess high floors and ceilings because even when they’re not accumulating strikeouts, they are still usually able to pound the strike zone. The list below shows pitchers with the highest drop-off in this rate... Read More

2020 RotoBaller Fantasy Baseball Mock Draft Reactions

Over the last couple weeks, RotoBaller's roster has grown with several new faces to join our esteemed veteran corps. We figured it would be nice to roll out the welcome wagon with a February fantasy baseball mock draft, putting six "RotoNewbs" with six RotoVets. It was a snake draft hosted on Fantrax, a traditional 5x5 format with... Read More

Kenta Maeda To Twins - Fantasy Impact

Late Tuesday night, the Los Angeles Dodgers and Boston Red Sox triggered a blockbuster, three-team trade that sent star outfielder Mookie Betts to the west coast and brought a couple of top prospects back to Boston. What was lost in the madness was the third team, the Minnesota Twins, making a big addition to their starting...

Going Full Corbin: Pitchers Who Should Throw Their Best Pitch More

Patrick Corbin has made a case for himself as one of the best pitchers in baseball. He produced 14 wins in 202.0 innings pitched with a 3.25 ERA and 28.5 K%. Corbin wasn’t always this good though. In 2016, his ERA was a pedestrian 5.15 with a mediocre 18.7 K%. Suddenly, Corbin decided to start... Read More

Analyzing Fly Ball Metrics: 2020 Negative Regression Candidates

Last week, I uncovered a few pitching casualties from the record-setting 2019 season, which saw an unprecedented amount of home runs hit and a "juiced" ball theory come into light. While the use of the defensive shift has caused more players to change their swing into a fly ball-oriented approach, this monumental increase in dingers... Read More

2020 Early Bullpen Outlooks - N.L. Central

We've covered all of the American League and the NL East, and next week we'll wrap things up with the National League West. This week, it's the National League Central's turn though.

Should We Buy Back Into Blake Snell?

Author note: Blake Snell dealt with an elbow issue ad received a cortisone shot. That lead to his ADP falling, and for good reason, but he returned to the mound since and now with the start of the season delayed, he should be ready for the start of the season.  Early in 2018, I was... Read More

Analyzing Fly Ball Metrics: 2020 Positive Regression Candidates

A once intermittent and revered event, the home run ball has now engulfed baseball to extraordinary levels, which has theorists convinced that the ball is tampered with or "juiced." For a good reason, as last year we saw four teams shatter the single-season home run record previously held by the 2018 Yankees, with the Minnesota... Read More

Nick Castellanos to Reds - Fantasy Impact

The winter of the Cincinnati Reds keeps rolling on. They already added some pitching in Wade Miley, a journeyman to play shortstop in Freddy Galvis, a power-hitting monster in Mike Moustakas, and a Japanese leadoff man in Shogo Akiyama. Now, they have secured one of the top outfield targets on the market in Nick Castellanos.... Read More

Using Sabermetrics for Fantasy Baseball: 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 always the case. Why would this be? The answer, of course, comes down to batted ball distribution and the manner in which batters make contact.... Read More

Marcell Ozuna to Braves - Fantasy Impact

When Josh Donaldson signed with the Minnesota Twins, it appeared the Atlanta Braves would be left with a giant hole in their batting order. We don't need to worry any longer, as they have fixed that problem by signing outfielder Marcell Ozuna. The 29-year-old Ozuna turned down the St. Louis Cardinals' $17.8 million qualifying offer to... Read More

Using Sabermetrics for Fantasy Baseball: BABIP for Hitters

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... Read More

Will There Be Fantasy Fallout for the Astros?

The Houston Astros have landed in hot water this offseason after receiving sign-stealing allegations against them dating back to their World Series championship season of 2017. A long and thorough investigation by MLB has confirmed that the elaborate scheme to notify batters of specific pitches was indeed true, and the organization is now facing the... Read More

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.
