BA scouting report on Ferreira:
Ferreira started to gain more notice as July 2 approached by showing remarkable arm strength for a 16-year-old lefty with a fastball that sits at 90-91 mph and has touched 93-94 mph. Ferreira has a projectable body and does it pretty easily with a loose arm, which means he could be throwing in the mid-90s in time. Aside from Ferreira's arm strength, scouts say he's not particularly athletic and the rest of his game is extremely raw. His changeup is a decent pitch, but his breaking ball is in its nascent stages (some scouts think he'll eventually throw a slider) and his control is below-average. The Braves have drafted and signed plenty of lefthanders in recent years and are believed to have interest in Ferreira, while some think the Yankees might also make a push.
