If a player can't handle pressure in ST, he's not going to be of much value. Especially a player old enough not to be able to use inexperience as an excuse. Herrera was always a long shot, and Quinn still has that long power swing that's going to destroy his career - how can a kid with his speed be thinking HR, he should be mono-focused on OBP.
Moniak, Kingery and Haseley will be the CF this year, maybe not until June but they are the most talented. Moniak seems to have rediscovered his swing, but with 20 lbs of muscle added. Haseley was stronger this spring, which was his biggest need. Kingery? Think they have to be patient, and help him recover his sweet, short stroke that he had before last season.
