After being claimed off of waivers in the spring of 2017, Aguilar burst onto the scene during the preseason. He blasted seven home-runs and made such a great early impression that he had a legitimate first base battle take place between him and newly signed Eric Thames.
Aguilar made the 25 man roster and would start out as a pure bench player that could be a good pinch hitter if needed. He would appear in 133 games and slash .265/.331/.505 to go along with 16 home runs and 52 RBIs. He clearly made quite the impression on the Milwaukee Brewers front office and opened the eyes of some die-hard fans.
