According to
ESPN's Keith Law,
five Red Sox prospects rank in the Top 50 in Major League Baseball. The highest-ranked Boston player (#8)—according to Law anyway—is
Rafael Devers. Devers is an 18-year old third-baseman, currently hitting .293 at Single A Greenville. Next in the ranking is 20-year old OF
Manuel Margot—coming in at #11. Infielder
Yoan Moncada—a teammate of Devers at Greenville—is ranked #14 by Law. LHP
Henry Owens gets the #37 ranking from Law. Owens has picked up the pace this year (after a troubling start to 2015) and is performing well at AAA. Finally, Law slots SS
Javier Guerra at #48.
