Chicago Cubs - 1B Patrick Wisdom
It's unlikely the Brewers and Cubs connect on a trade at all, but from a baseball perspective, a Patrick Wisdom trade makes some sense. Wisdom is now splitting time at first base with Matt Mervis and he's a pure power bat. Wisdom hit just .205 but he slugged 23 homers. Milwaukee needs an infusion of power in their lineup and Wisdom brings just that.
St. Louis Cardinals - C Andrew Knizner
The career backup catcher has been improving as a hitter but his defense is quite lacking, which is not great for a backup catcher. But the Brewers have proven adept at improving catchers defensively and with William Contreras' improvement in that department, they can focus less on finding an already great defensive backup.
Cincinnati Reds - INF Jonathan India
It's been speculated by many that Jonathan India is a logical trade candidate. The Reds have promoted a plethora of infield prospects and have even more in the pipeline. There simply isn't room for all those young players and India. India was drafted by the Brewers out of high school (he didn't sign) and Milwaukee has a need in the infield. Trading India within the division may be unlikely, but the needs do line up.
Pittsburgh Pirates - RP Ryan Borucki
Borucki is a relatively experienced big league arm and put up good numbers this year out of the Pirates bullpen. He's a left handed reliever and entering his last year of arbitration. The Brewers could look to pick him up as an extra southpaw besides Hoby Milner for pretty cheap. The Pirates and Crew have linked up on trades a number of times in recent years.
