In their 24 seasons, the Rockies never have had a rookie class as strong as their 2016 group. Trevor Story set home run records beginning on Opening Day, Jon Gray looked like the frontline starter Colorado hoped for when it drafted him third overall in 2013 and David Dahl tied a big league record by hitting safely in his first 17 games. Tyler Anderson, Carlos Estevez and Tony Wolters also graduated to Coors Field.

There's plenty more talent where that came from. Even without those players, the Rockies still have one of the best farm systems in baseball, checking in at No. 8 in MLBPipeline.com's annual rankings. They have good balance, with depth in both position players and pitchers and quality prospects spread throughout all four of their full-season clubs.

• Rockies' Top 30 Prospects list

Colorado has another wave of rookies poised to contribute as it attempts to return to contention in 2017. Right-handers Jeff Hoffman and German Marquez and catcher Tom Murphy will press for starting jobs after getting some time with the Rockies last year. Lefty Kyle Freeland, outfielders Raimel Tapia and Jordan Patterson and relievers Rayan Gonzalez and Sam Moll also are ready if needed.
