Today's coaches need to add to their duties serving as interpreters for the analytics department so information is communicated to players in ways the players understand and that make the information actionable.
Does he have any options left? No mediocre pitchers should be kept on the 40-man roster unless they have at least one option remaining. Mediocre pitchers without options can be replaced from the waiver wire.
If Rutschman and Diaz develop into ML All Stars, I'll be happy if Hays turns out to be a good defensive CF who bats seventh and hits some home runs despite having a low OBP. Not everyone on a good team needs to be great.
That's why I had the O's kicking in a few million dollars to increase his value. He would be a one-year rental, so his new team would have a limited time to enjoy what surplus value there is.
I expect they will mostly platoon Hays and Willams in CF. with a little Santander and Wilkerson sprinkled in. There are too few games left for Hays or Williams to prove anything with the bat, but good defensive showings would help build a case.
