He has a career wRC+ of 78 vs. LHP, including wRC+'s of 3, 84 and 57 over the past 3 years (yes....wRC+ of 3 vs. LHP in 2016). Given this - along with the reality that his base running and defensive value continues to erode, I think you'd have to be incredibly short-sighted to pay him as, and expect him to be a full-time player.
That said - he's still a very strong player on the strong side of the platoon. Platoon's are much more accepted and used in this day in age, so it will be interesting just to see what the market for a LH platoon bat is.
