Breaking down the Dodgers' Top 30 Prospects

Los Angeles farm remains among baseball's best despite significant graduations

Breaking down the Dodgers' Top 30 Prospects

The Dodgers farm system topped MLBPipeline.com's rankings a year ago. It paid immediate dividends with National League Rookie of the Year Corey Seager, the precocious Julio Urias, surprise contributor Andrew Toles and the trade fodder to land midseason reinforcements Rich Hill and Josh Reddick.

Gunning for its fifth straight NL West title, Los Angeles has a crowded roster and more young talent coming from a system that currently ranks as the sixth-best in baseball. First baseman/outfielder Cody Bellinger, right-hander Brock Stewart and catcher Austin Barnes would be pushing for starting roles on a lot of clubs, but they'll have to wait their turn. Outfielder Alex Verdugo, second baseman Willie Calhoun and righty Walker Buehler -- all Top 100 Prospects -- are only a year away.

The Dodgers went all in during the 2015-16 international signing period, spending more than $150 million on bonuses, guaranteed salaries and overage tax. Right-hander Yadier Alvarez may make his $16 million bonus (and another $16 million in penalty tax) look like a bargain. Several other members of that crop should have bright futures, including outfielders Yusniel Diaz and Starling Heredia and infielders Omar Estevez, Ronny Brito and Oneil Cruz.
