I continue to be intrigued by how the Pirates are using their prospects in the majors.
Yesterday’s games, for example, featured four players who you might not have expected in the majors this soon. Diego Castillo and Jack Suwinski both appeared in the lineup, while Beau Sulser and Max Kranick both pitched.
We’re still in the early stages of understanding how the Pirates will handle prospect promotions under Ben Cherington. The four players above are key data points in understanding those promotions.
Castillo was acquired last July in a trade with the Yankees. At the time, he was in Double-A for his first appearance.
