15. Sean Coyle, 2B/3B, Double-A Portland
Coyle doesn't get much national recognition, but the infielder is hitting .336/.412/.585 in 251 PA in Portland as a 22-year-old, and he's showing some defensive versatility, too. He might not profile as a first-division starter at the next level, but he's going to enjoy a career as a major leaguer, and he'll rely on the strength of his bat to get there. Coyle draws Dustin Pedroia comparisons because of his stature, and while such a parallel is unfair to Coyle, it’s true that he has more power than his frame would suggest.
14. Trey Ball, LHP, Single-A Greenville
Ball's had an awful first full professional season, struggling to the tune of a 6.59 ERA and 1.82 WHIP in 57.1 innings in Greenville. If the scouting reports weren't also so negative I wouldn't drop Ball this far, but the left-hander is getting hit hard and isn't showing much progress with his breaking stuff. He's still a prospect, but things aren't looking great right now.
13. Rafael Devers, 3B, Rookie Level GCL
Devers was a big get for the Red Sox during the 2013-14 international signing period, and he's impressed in a major way in his early taste of professional ball. After tearing apart the Dominican Summer League for 28 games, Devers was recently promoted to the Gulf Coast League, where he's hitting .500/.552/.962 through seven games. He'll take a long time to progress through the system, but he's a tremendous power-hitting prospect.
12. Michael Chavis, SS, Rookie Level GCL
The Red Sox's first pick of the 2014 draft, Chavis is praised for his quick swing, defensive versatility and surprising power for a player of his stature. A high-energy player with a good feel for hitting, Chavis could progress through the lowest levels of the minors fairly quickly, though he's still a long way away. He's playing shortstop now, but most project a move to third base or second base in the near future.
11. Brian Johnson, LHP, Double-A Portland
When the Red Sox drafted Johnson in 2012, he was billed as a fast-moving starter with a low floor but a high probability of reaching the majors as a starter. Injuries have slowed Johnson to some extent, but he's really taken off this year, posting a 2.51 ERA through 71.2 innings in Double-A to this point. He's not higher here because his upside is as a No. 4/5 starter, but he could realize that future as soon as next season.
