Colorado Rockies: 3 interesting non-roster invitees to watch this spring

Castellani is one of the most intriguing young pitching prospects in the Rockies system. The 6-foot-4 right hander was drafted after high school in 2014 and has been in the Rockies system ever since.

This year, he worked his way up to Double-A Hartford and pitched much stronger than his 9-12 record would indicate. A few poor outings lifted Castellani’s ERA to 4.81, but overall he had a very solid season.

The highlight of Castellani’s season this year came in a game against the Portland Sea Dogs, the star studded Double-A team of the Boston Red Sox. He pitched a complete game three-hitter, baffling some of Boston’s brightest star prospects in the process.

He has some Major League connections as his mother started working for the Philadelphia Phillies nearly 30 years ago and eventually moved into their front offices. Castellani has said that he hopes to follow in his mom’s footsteps and make it to the major leagues.

This spring, he will try to get one step closer to his dreams during Spring Training. A strong showing with the big league club now could set him up for future success the rest of the season.
