I thought this was interesting:
Basically, the idea is that xwOBA via statcast can routinely over/underrate certain guys A) because they're notably fast or slow or B) because their lateral launch angle is bad (e.g. you hit the ball really yard but are very easy to shift against), and this is an attempt in correcting for the latter. The rightmost column is essentially how lucky guys were based on launch angle (vertical and lateral) and exit velo. I threw this table into excel and calculated standard deviations, and found that of the 337 guys on the list 17 of them were more than 2 standard deviations from the mean. That's a good rule of thumb for what is sufficiently outlier-y. Of the 17, 3 will be in the NL Central next year: Keston Hiura and Phil Ervin on the lucky end, and Justin Smoak on the unlucky end. Hiura in particular stands out, as he was the second luckiest guy on the list, and as an average runner you can't just chalk the delta up to his ability as a runner. If you lower the bar to 1.5 standard deviations, Yelich, Kolten Wong, and Kevin Newman get added on the lucky side. That being said, unlike Hiura all three guys are pretty fast, so you expect that they should overperform this metric by a decent bit. For the Cubs, nothing stood out too much. Contreras and Bote were both at 1.3, but as above average runners that's not super alarming. Bryant and Baez were at 1, but again given their speed that's about expected. Schwarber was the biggest laggard on the team at -1, and he's an average runner. So maybe bake in a little bit of extra good fortune for him going forward.
