Prospect pitching isn't a figment of your imaginations.
Tolle, Valera, Clarke, Early and Connelly are all legit. There are several others with intriguing tools though as pitchers are challenged at each level their warts become more evident. Tolle is a beast and seems mentally strong to handle the crush that comes with rising expectations. Trade him could be regrettable.
Same, too, with Anthony., a potential marquee performer capable one day of putting the team on his back, especially with the supporting cast Bloom assembled. I've seen all these guys, and there should be more optimism than I'm reading here.
