Finally, it’s time for the main event! After weeks discussing the various xHR/FB rate components and reviewing 2019 performance, we now set our sights toward 2020. Today, I will identify and discuss a handful of fantasy relevant names that underperformed their xHR/FB rates most significantly. Remember that this doesn’t automatically mean we should be projecting a higher HR/FB rate this season. But perhaps rather than take the hitter’s actual HR/FB rate at face value, we should substitute our xHR/FB rate mark when reviewing his historical marks and making a 2020 projection.

Last week, I identified and discussed a slew of hitters whose xHR/FB rates validated their surprisingly strong HR/FB rates. Today, let’s look at some of the disappointing hitters in HR/FB rate that were validated by a dramatic decline in xHR/FB rate. Remember, an appearance here doesn’t mean these hitters should be projected to repeat their disappointing 2019 marks, as this is merely a backward-looking analysis. We need to account for additional factors when making a projection. But all else equal, the guy with an xHR/FB rate validating his disappointing HR/FB rate should be expected to have a worse chance of rebounding than the guy who suffered a disappointing actual mark, but underperformed his xHR/FB rate.

Over the past couple of weeks, I’ve been sharing various hitter lists focused on the components of my xHR/FB rate equation. Today, I want to share yet another list. This time, we’re not going to look at the individual components, but rather the xHR/FB rate itself. Just like every other year, there were breakouts and busts. Some of them lucked their way into surprising HR/FB rates, while others seemingly deserved such results. The opposite is true as well, with some batters suffering from poor luck, which dragged down their HR/FB rates, while others suffered a real decline in power.

After signing free agent Kole Calhoun, the Diamondbacks apparently weren’t done adding outfielders. On Monday, the team acquired Starling Marte for a pair of prospects. The knee-jerk reaction is that this must be a positive for Marte’s contribution on offense given the perception of PNC Park as an extremely pitcher friendly environment. Do the park factors confirm this sentiment?

Yesterday, I identified and discussed a slew of surprising names among the average fly ball distance (AFBD) leaders. Today, I’ll check in with the laggards. Which hitters finished closer to the bottom of the barrel than the top that we never would have expected?

A couple of weeks ago, I listed and discussed the average fly ball distance (AFBD) surgers and decliners. As a reminder, AFBD is one of the main components of my xHR/FB rate equation. Today, let’s review some of the surprising AFBD leaders. We’ll define surprise as hitters we didn’t predict to appear anywhere near the top tier in the rankings. I’ll only call out fantasy relevant names.

Though we’ve known about it for a week now, Josh Donaldson has officially signed with the Twins, which pushes Miguel Sano to first base. Donaldson now joins his fourth team in three years, which is surprising given how good he has been, outside a down, injury-marred 2018. Speaking of 2018, he rebounded off that disappointing performance admirably, proving it was health, not age, that was the issue. He now returns to the American League after a year in Atlanta. What might the change in home park do to his results? Let’s consult the (2018) park factors.

Wow, in a surprise twist, free agent Marcell Ozuna settled for a one-year deal with the Braves. He now joins the third team of his career as he enters his age 29 season. So how might his offense be affected by the move from Busch Stadium (Cardinals) to Truist Park (Braves)? Well first, he has to tell his friends and family that he’ll be playing his home games at a stadium called Truist Park without laughing. That has to be the worst stadium name in all of sports right now. Outside of that challenge, let’s see what the park factors say (well, at least the 2018 ones!).

Yesterday, I identified and discussed a smattering of hitters who made surprising appearances near the top of the barrels per true fly ball (Brls/TFB) leaderboard. Today, we flip to the opposite end of the list, moving to the laggards. These are going to be fantasy relevant guys you never expected to appear closer to the bottom of the leaderboard than the top.

Last week, I listed and discussed the barrels per true fly ball (Brls/TFB) surgers and decliners. As a reminder, Brls/TFB is one of the main components of my xHR/FB rate equation.
