Ok, let’s get this part out of the way right from the start. Sam Hilliard is currently running a 166 wRC+ with a 39% strikeout rate and a .545 batting average on balls in play. That profile hasn’t exactly a zero percent chance of maintaining itself over a full season, or even half a season. This is a classic “April profile” that only exist in the wild and random first month of a baseball season.
So the question is not “Can Sam Hilliard keep this up?” Cause the answer to that question is a clear no. No one can.
