Espinal with more power is massive given his flexibility.
WAR doesn't directly take into account position flexibility, but having an above average bat that can be pencilled in to any IF position and probably the corner OF positions in a pinch is a WAR bonus (+20%?). And all indications are he's a great teammate / clubhouse guy (+10%?).
His wrC+ is 99, with a .229 babip. His 15% above average bat in 2021 is probably accurate, maybe even a bit low.
Give this kid a 6 year contract now.
