1. Matt Chapman
Other than Cody Bellinger, Matt Chapman is the most in-demand position player in this year's free agent class. It's likely that some of that has to do with his otherworldly April, when he hit .384/.465/.687 with a 1.152 OPS, five home runs and 20 RBI. He lost more than a little of that oomph through the rest of the year (.205/.298/.361), but his lifetime .240/.329/.461 and reputation for being an capable defensive third baseman led MLB Trade Rumors to estimate that a six year, $150 million contract could be headed Chapman's way.
Despite his uneven 2023, Chapman is clearly still capable of flashing the same kind of offensive greatness he displayed for the Oakland A's in 2018 and 2019 (he accumulated 12 fWAR over those two years), even if it is more unpredictable. He also finished the season with a positive OAA that was third highest on the Blue Jays, so he's still adding defensive value. Clearly, Chapman would be the most expensive and competitive option for the Brewers, but he could be a strong addition in the pursuit of keeping Milwaukee at the top of the NL Central next year.
