Gregorius has been the best hitter in baseball so far in 2018. While he's unlikely to maintain his current pace, there plenty of positive signs in his profile to suggest he's worth holding on to.
The best player in baseball through the early portion of the 2018 season has not been one your typical suspects -- it's been Didi Gregorius.

While Gregorius' offensive boon has been great so far, it is important to see how sustainable any of this is moving forward.
