Greenville Drive (Class A)
The Drive will have a good problem in a few weeks once Cuban infielder Yoan Moncada arrives from extended spring training; they'll have him, third basemen Rafael Devers and Michael Chavis, and shortstop Javier Guerra all fighting for playing time at three infield spots. Moncada was a shortstop as well, but won't play there in the long term, likely moving to second or third base, but the logjam probably means we'll see all four players switch positions frequently and get some time at DH too. Outfielder Nick Longhi has real power potential from the right side, signing with the Red Sox for an over-slot bonus of $440,000 in the 30th round in 2013. The rotation has their second pick from last year, right-hander Michael Kopech; 2012 fourth-rounder Ty Buttrey, who received a first-round bonus but has yet to deliver on his promise; and lefty Williams Jerez, signed as an outfielder in 2011 but converted to the mound after 2013, showing immediate arm strength and surprising control out of the chute.
