15. Michael Chavis, SS, GCL Red Sox

Boston's first pick from the 2014 draft, Chavis profiles as an everyday starter at second or third base, though he's still eons away form reaching the majors. There's no superstar potential here, but Chavis could bloom into an above-average infielder on a first-division team. His bat speed is legit.

14. Edwin Escobar, LHP, Triple-A Pawtucket

Acquired from the San Francisco Giants in the Jake Peavy trade, Escobar has better stuff than the man who precedes him, Brian Johnson, but is plagued by inferior command. That being said, the southpaw is still just 22 and in Triple-A, so some patience is needed. He's a potential back-end starting option, but he could be ready to contribute next year.

13. Brian Johnson, LHP, Double-A Portland

Johnson's eye-popping stats belie what's a very average arsenal of pitches, including a fastball that often fails to break 90 mph. He also doesn't always flash plus secondary pitches, as Baseball Prospectus' Tucker Blair pointed out on Twitter on Tuesday night. There's a future major leaguer here, but not one who profiles as more than a No. 5 starter in the AL.

12. Rafael Devers, 3B, GCL Red Sox

Red Sox fans have wasted no time getting the hype machine started with Devers, and one look at his swing will tell you that the excitement is warranted. He's still likely four-plus years away from the majors, though, so expectations must be tempered even if the upside here is sky-high.

11. Matt Barnes, RHP, Triple-A Pawtucket

It feels strange to see Barnes outside of the Top 10. But a down year for the right-hander coupled with the ever-improving depth in Boston's system has led to the 2011 first-rounder falling to No. 11 in this iteration of this list. Barnes' last three starts have been pretty good, but that's not enough to make up for his 4.45 ERA and declining strikeout rate. A move to the bullpen could be in the cards if he struggles in the first half of 2015.
