In the shortened 2020 season, Pillar hit .288/.336/.462 with six home runs, five stolen bases, and a 108 wRC+ in 223 plate appearances for the Red Sox and Rockies. It was his best season as a hitter, and combined with his play in the field, it made him worth 1.1 fWAR.
Over the course of his career, Pillar has hit .262/.299/.408 with an 87 wRC+, having built much of his reputation upon his defense. For what it’s worth, both his DRS and UZR/150 have turned from consistently in the positive to consistently negative in recent seasons in center field.
A right-handed hitter, Pillar has a career .286/.320/.464 line with a 107 wRC+ against left-handed pitchers. Considering the Mets’ collection of left-handed hitters who would likely spend time in the outfield, Pillar could be a good fit.
