Making Sense of Tampa Bay's Pitching Staff

OK, seriously — is there any tougher pitching staff to decipher in fantasy than Tampa Bay's? Between the never-ending merry-go-round that is their closer committee, their frequent use of openers and then the normal issue of back-end rotation guys not being fantasy assets, it can be difficult to stay on top of which pitchers you […]

Statcast Hitter Studs and Duds - Fastball Run Values (Week 13)

The news regarding MLB's unexpected crackdown on foreign substances has been well-documented by now.

Statcast Hitter Studs and Duds - xSLG Analysis for Week 12

Slugging is a fairly simple metric by baseball standards but once Statcast gets into the mix, it's a bit more complicated. According to MLB.com, "Expected Slugging Percentage (xSLG) is formulated using exit velocity, launch angle and, on certain types of batted balls, Sprint Speed." Base hits are still weighted with home runs being four times […]

Statcast Hitter Studs and Duds - Barrel Rate Analysis for Week 11

Believe it or not, this will be our first foray into barrels this season. Certain statistics take longer to become significant, so it made sense to accumulate more data before digging into barrels. Those familiar with this series already know that the obvious names like Aaron Judge, Vladimir Guerrero Jr., and Nelson Cruz won't be […]

Which Pitchers With New Pitch Usage Should We Care About? Part Seven

One of the things we are constantly reading about during the early stages of the baseball season is pitchers adding new pitches or making major changes to their pitch usage. However, as the season goes on, those changes can be abandoned and pitchers go back to what they do/know best. So it's important to continue […]

Are You For Real? Surprising Pitcher Starts from Week 9

It was a week of young guns in the fantasy baseball world as we saw excellent outings from tons of young, exciting pitchers around the league.

Statcast Hitter Studs and Duds - xBA Analysis for Week 10

Death, taxes, regression. These are inevitable. Eschewing the first two topics, fantasy baseball managers may be interested in identifying batters who are experiencing regerssion, both positive and negative.

Hitters That Aren't Missing Their Pitches

One thing that the analytical world of fantasy baseball doesn't talk much about is the quality of pitches seen by hitters. We have numbers to quantify almost everything in the game, but when we are viewing those numbers we somewhat assume that hitters have all seen the same set of pitches. Everybody knows this isn't […]

Are You For Real? Surprising SP Starts from Week 8

As we approach Memorial Day, season-long numbers are starting to feel a lot more real. That makes it even more important to analyze surprising starts from pitchers who may not have been caught up in the whirlwind of April breakouts.

Statcast Hitter Studs and Duds - Sweet Spot Analysis for Week 9

Barrel rate is one of the best measures of a hitter's power. In order to earn a barrel, a player needs to have enough exit velocity, which we measured last week, and the proper launch angle. Specifically, a ball can travel anywhere between 8-50 degrees depending on how high an exit velocity was produced. Although […]

The Best Pitches of 2021 By The Numbers

There is so much to look at when evaluating pitchers in 2021. The amount of data we have is incredible. At the time of this writing, there had been 186,220 pitches thrown this season. I wanted to examine the individual pitch types and see which pitchers have been most effective with each. I am mostly focusing […]

Barrel-Aged: Hitters With Biggest Barrel Gains

Lately, I've been focusing a lot on barrels when trying to evaluate which hitters are off to the most note-worthy starts. I recently covered Blast Rate, which is a sub-section of barrels that aims to tell us who is making the "best" good contact. Today, we'll focus on who has shown the best growth in […]

Are You For Real? Surprising SP Starts from Week 7

Statcast Hitter Studs and Duds - Exit Velocity Analysis for Week 8

Exit velocity is all the rage these days, but how meaningful is it really? It depends. A high exit velocity is worthless if it's smashed into the ground right at a defender.
