You must have a very liberal definition of “premier power bats in all of baseball”. Sure, Saurez hits homeruns but literally doesn’t do much else. Since he turned 30 his OBP is .320. He’s 2nd among all active players in errors, 4th among active players in strikeouts yet is only 18th in games played amongst active players.
Not only that, the Reds signed him to a big extension in 2018 and since then he’s been traded twice in salary dumps.
Saurez couldn’t hold the jock of the real premier power bats like Ohtani, Judge, Soto, etc.
Who knows, maybe the Brewers will feel it crucial to add homeruns to their roster, but Saurez is kind of the antithesis of the type of player the Brewers value.
