The Brewers fell one win shy of their first World Series appearance since 1982 last season, ultimately losing to the Dodgers in Game 7 of the National League Championship Series. NL MVP Award winner Christian Yelich and center fielder Lorenzo Cain led Milwaukee's resurgence in their first year with the organization, and together they provided the front office with a elite talent core to build around through trades and prospect promotions.

Much like Josh Hader in 2017, Corbin Burnes (No. 2 on the '18 Top 30) and Brandon Woodruff (No. 3) were developed as starters in the Minors only to be shifted to the bullpen to help the big league club. Both were outstanding down the stretch, especially Burnes. Freddy Peralta (No. 10) and his disappearing fastball struck out 13 batters in his Major League debut at age 21 and averaged 11 strikeouts-per-nine over 78 1/3 frames as a rookie.

Keston Hiura is perhaps the club’s best prospect since the Prince Fielder/Ryan Braun era more than a decade ago. He should rake his way up to the Majors in 2019, perhaps quickly, and it’s easy to picture Corey Ray finding his way into the outfield picture with his plus power and speed. Mauricio Dubon would have reached the Majors early last season had he not suffered a torn ACL in Triple-A.

The system is a bit thinner with regards to big league-ready pitching prospects, though Zack Brown looks ready to make an impact as either a starter or reliever. He and Ray took home the Double-A Southern League’s Most Outstanding Player and Pitchers awards, respectively, in 2018.

And while the Brewers have quickly turned around their fortunes in the Majors, they’ve also been targeting high-ceiling teenage prospects at premium positions in the Draft and via the international market, giving the system a future wave of talent that could help mitigate a possible roster turnover after Yelich and Cain’s contracts expire.
