Breaking down the Red Sox's Top 30 Prospects

Moncada, Swihart lead impressive group ranked as MLB's second-best farm system

Breaking down the Red Sox's Top 30 Prospects

What's more impressive? That the Red Sox graduated Mookie Betts, Xander Bogaerts, Jackie Bradley Jr. and Christian Vazquez to the big leagues in 2014? Or that they have baseball's No. 2 farm system without those players and trade chips Anthony Ranaudo and Allen Webster?

Betts (fifth round) and Bradley (supplemental first) were part of a 2011 Draft crop that could stand up as the game's best of the decade. Blake Swihart (first) is the top catching prospect in the Minors, Henry Owens (supplemental first) is one of the top left-handers and Matt Barnes (first) is a power-armed right-hander who could be a mid-rotation starter or maybe a closer.

Boston's system got even stronger when it spent $63 million earlier this month to land Cuban second baseman Yoan Moncada, who has the upside of a Robinson Cano, with more speed. It was the latest big move for the Red Sox' international program, which has slugging third baseman Rafael Devers, speedy outfielder Manuel Margot and slick-fielding shortstop Javier Guerra advancing toward Fenway Park.
