Hays has a 617 OPS since last July 1. 71 wRC+ and 269 wOBA.
Now, it’s hard to compare the 2 because McKenna is a part time player but since the beginning of last year, McKenna has 148 PA. His OpS is over 100 points higher, his wRC+ is 105 and he has 320 wOBA.
They both have an OAA of -1 between last year and so far this year.
Now, these are different roles and my guess is McKenna would be exposed playing everyday but guess what, Hays is also being exposed for the last half a year. I think he will be ok going forward but there is no definite there.
So, I think an argument exists and it’s a pretty obvious one. It’s just not likely a super strong argument because we don’t have any idea about McKenna in an expanded role.
There is certainly an argument where the drop off isn’t much right now
