Mullins' walk rate seems to be collapsing this year so I am not sure that we want him for 2 years. He is probably a little better than Marsh in CF but really not much better.
I still like the idea of Winker. LH bat that would push Marsh into CF more often. Still let Rojas play CF against LHP and against certain teams or with pitchers like Wheeler who give up more fly balls. Winker/Wilson in LF, Marsh/Rojas in CF. The defensive alignment with Mullins might be a bit better pushing Marsh to LF, but Winker is that 800 OPS bat we probably need.
Then the question is would I give up Klassen for Winker. I might.
