Crawford tops list; Nola one of five pitchers in top 10 who weren't with organization to start 2014

Breaking down the Phillies' 2015 Top 30 Prospects

Starting with the First-Year Player Draft last June and continuing into the offseason, the Phillies have acquired a significant amount of young talent in the past eight months, which is reflected in their 2015 Top 30 Prospects list. Right-hander Aaron Nola, the seventh overall pick in 2014, is one of five pitchers ranked in the top 10 of this year's list who weren't a part of the organization at the start of last season.

Shortstop J.P. Crawford, the club's first pick in the 2013 Draft, has taken over the top spot on the list following a stellar first full professional season. He earned All-Star honors in the South Atlantic League and continued to play well after a midseason promotion to Class A Advanced Clearwater.

Right-handers Franklyn Kilome and Ricardo Pinto haven't reached full-season ball yet, but they put themselves firmly on the radar in 2014. Along with catcher Deivi Grullon and outfielder Cord Sandberg, they represent the organization's next wave of budding prospects.
