You can see Heyman’s story here.
Twenty-eight year old Alcides Escobar is having a poor season both at the plate and with the glove according to most advanced metrics. His .314 slugging percentage is the worst mark in the league for any qualifying regular in major league baseball, and even defensive metrics like Ultimate Zone Rating (UZR) and Defensive Runs Saved (DRS) put him at below league average in the field (negative numbers). As a result, both Baseball-reference and Fangraphs.com rate Escobar as a below replacement level player in 2016.
That’s pretty bad.
