Despite recording 86 wins and finishing just a game out of the Wild Card in 2017, the Brewers have been pretty quiet this offseason. Of course, a lot of teams have been pretty quiet this offseason. Milwaukee added Jhoulys Chacin, which helps, and they’ve brought back Yovani Gallardo, which might help. But little more than that.

Well, until now. The Brewers’ offseason just got loud. In the midst of a busy winter themselves, the Marlins — who’ve already moved Giancarlo Stanton, Marcell Ozuna, and Dee Gordon — have now sent what is likely their most valuable asset, Christian Yelich — to Milwaukee.

Ken Rosenthal of the Athletic had it first, and the Brewers made it official.

Brewers receive:

• Christian Yelich, OF

Marlins receive:

• Lewis Brinson, OF
• Monte Harrison, OF
• Isan Diaz, INF
• Jordan Yamamoto, RHP

We expected that the package would be significant given Yelich’s talent and a contract that will pay him around $10 million a year for the next five seasons. It is big with Brinson as the headliner. The young outfielder just appeared 18th on Baseball America’s recently released top-100 list, while Eric Lohenhagen placed a 60 future-value grade on Brinson, making him one of the best prospects in baseball.

The deal isn’t just Brinson and filler, either. Longenhagen listed Monte Harrison as the third-best prospect in the Brewers system, with Isan Diaz close behind at the six spot. All three profile as average regulars at least. Yamamoto is more of a project, but he has an above-average curveball.

Just a few days ago, Jeff Sullivan examined a potential Brewers trade for Yelich:

What the Brewers have assembled is a cheap, young foundation. They have dozens of would-be major-league contributors, average starters or plug-in role players. Everyone has his own share of upside. But looking at the 2018 Steamer projections, the Brewers don’t have a single player in the top 150. By WAR, you find Jimmy Nelson ranked at No. 156, and Nelson seemed to break out last season as an ace, but he’s also going to miss the start of the regular season, because he’s coming off major shoulder surgery. And Nelson, it turns out, is the Brewers’ only player in the top 300. I don’t mean to suggest that Steamer is flawless, and I don’t mean to suggest that Ryan Braun or Domingo Santana or Chase Anderson are bad. But this isn’t a club with an obvious star. The best player is a question mark, because of his health. Stars aren’t everything, but good teams tend to need them, which could explain the Brewers’ pursuits. They know they already have plenty of upside, but it’d be good to also have some higher-end certainty.

The Brewers have that higher-end certainty. They might still do more.
