Lewis Brinson appears the closest to a lock to play in center field. Brett Phillips could push Domingo Santana into the trade market. Ryan Braun is suited for a move to first base at some point and he’s made it clear that he’s not changing addresses.
The issue for me is that it’s hard to project a Major League roster even two years out. Players get hurt, get traded, and don’t perform like they should. The Milwaukee Brewers also have a glut of athletic, young outfielders who are going to push for playing time. Monte Harrison appears poised for a breakout in 2018. Corey Ray is a year removed from being the fifth best amateur player in the country.
There are probably two or three guys that we aren’t even thinking about like Tristen Lutz who could push for playing time. The Brewers could even draft a college outfielder next June who could force his way onto the roster by 2020, or add a Cuban or Japanese outfielder who wants to make the jump.
If I’m making a prediction for 2020, I’ll go with Phillips, Brinson, and Harrison with Braun playing first as the most likely option, but there are a ton of moving parts here.
