More info to come in a forthcoming Fangraphs Community post… You can use the tool below to convert a projected triple slash line (AVG/OBP/SLG) to a fantasy line (HR/R/RBI/SB/AVG). A few optional things can be used to improve the projected fantasy line… Batting order: Must be an integer between 1 to 9. Determines overall […]

Entering now into part four of my preseason player valuation series, we arrive at one of the more important decisions of the preseason: deciding which projection system(s) to use. Evaluating projection systems is well-trodden ground, as documented by Will Larson over at the Baseball Projection Project. This year, I’ve only yet seen analysis of the 2015 projections over at Beyond the Box Score, and in that case it was not a specifically fantasy-focused analysis. Each of the projection systems changes and iterates their methodology year over year, and so we can always stand to learn more by analyzing the most recent year’s results.

One of the most frequent topics of discussion at this point in the offseason is trading. Everyone in keeper leagues is trying to shore up their team to get ready for a 2016 title run (or sadly in some cases, getting rid of flotsam following a disaster 2015). xaheyjg Download the free 5×5 version here!

A question that tends to pop up around this time of year: “When does fantasy baseball season start?” Of course, we all know that fantasy baseball season never ends, especially for those of us in keeper and dynasty leagues. To wit, Brad Johnson’s “Keeper Questions” thread posted just yesterday at FanGraphs is now sitting at 350 comments and growing. As we all collectively count the days ‘til spring training and opening day, one of the most oft-discussed and most subjectively-answered topics is “Who do I keep?” Fantasy baseball players intuitively understand the idea of aging, at least qualitatively. Older players are less valuable, given that their performance is more likely to decrease due to both injury and ineffectiveness. But how much is age worth, really?

z-Score: a statistical measurement of a score’s relationship to the mean in a group of scores. A z-score of 0 means the score is the same as the mean. A z-score can also be positive or negative, indicating whether it is above or below the mean and by how many standard deviations.
After throwing around the terms z-score and BIGz somewhat haphazardly on this site, I figured the time has come to explain where it all comes from. For the math-inclined individuals among you (and you play fantasy baseball, so I’m not sure why I have to qualify that), this will hopefully satiate your need to understand where all the numbers in the Big Board come from. This is also going to theoretically empower you to create your own Big Board, but hey, save yourself some (read as: A LOT of) time and buy the one hosted on these very interweb-pages. More generally, this breaks down one of the more popular methods for creating player rankings and dollar values, sometimes referred to as ‘FVARz’ for Fantasy Value Above Replacement z-scores as popularized by Zach Sanders of Fangraphs.
