On The Ledge: Pitchers You Aren't Sure About



On The Ledge


The pitchers below have certainly hurt a lot of fantasy baseball owners in the past, leaving us wondering if we could trust them. Below are some mini deep dives into a few of those names. Figuring out what is real and what is a mirage in fantasy baseball provides a huge advantage.

The second thought is movement, but the horizontal movement hasn’t really changed either. This leaves his 2018 four-seam fastball as an outlier and if Alex Chamberlain has taught us anything lately it is that xwOBacon should be looked at to search for outliers. Here are Trevor Bauer's xwOBAcon by year.



In 2018 not only was his xwOBAcon out of the norm, but it was the only year that showed severe regression coming for his fastball based on wOBAcon. This leads us to believe that his four-seam in 2018 was lucky and perhaps will never be th
