In addition to that group, the Braves' list also includes their top three picks from the 2014 First-Year Player Draft and another from the Rule 5 Draft, meaning half the players on the rankings have joined the organization in the last year.
Atlanta's top prospect has also changed from this time last year, though it's not one of the new faces. Second baseman Jose Peraza took off in 2014 and unseated right-hander Lucas Sims atop the rankings in the process. Right-hander Mike Foltynewicz is the top-ranked newcomer, slotted just behind Peraza.
