In the last two years, the Dodgers system has produced consecutive unanimous National League Rookies of the Year in Corey Seager and Cody Bellinger , a starting catcher in Austin Barnes , a potential (if currently injured) ace in Julio Urias and lots of ammunition to swing deals for Scott Alexander , Yu Darvish , John Forsythe , Rich Hill, Josh Reddick , Chris Taylor and Tony Watson. And there's more where that came from.

• MLB's Top 10 farm systems | Dodgers Top 30 Prospects list

Right-hander Walker Buehler and outfielder Alex Verdugo are gifted enough to give Los Angeles a third straight Rookie of the Year, though they may not get enough playing time to do so. Catcher Keibert Ruiz and righty Mitchell White aren't nearly as famous but are almost equally as talented.

Verdugo and Ruiz headline the system's two greatest strengths, outfielders and catchers. All those graduations and trades may have dropped the Dodgers from No. 1 in MLB Pipeline's talent rankings in 2016 to No. 10 today, but there's plenty of quality to pull off some more significant deals when needed.
