Very interesting take from a guy freshly out of the Astros scouting department:
https://blogs.fangraphs.com/scouting-three-potential-first-round-arms/
More so than the actual content, a few things about the evaluation process jump out at me...
1. He grades these guys based on a dollar value. This seems like a way to map them to a draft slot, as well as works to set up pool allotment to various draft strategies (saving on some guys to spend more on others).
2. He is very interested in fastball shape, almost more than velocity. His preference for the rising FA seems to me it could be opening up the door for sinking action to be undervalued.
3. The fact he is commenting on pitch shape leads me to assume he has access to Statcast data for these guys. How??
The guys he scouted in this piece...
Ty Madden
Value: $4.5M = Pick 11
Money quote: Prototypical starting pitcher in terms of frame/delivery, with plus velocity and plus shape to fastball to go with a slider that could be a difference maker.
Gunnar Hoglund
Value: $3.25M = Pick 20
Money quote: ...breaking ball is one of the best in the draft... Worries about the fastball in terms of velocity and pitch shape.
Gavin Williams
Value: $2.75M = Pick 25
Money quote: Good velo/bad shape guy who will need to maintain the giddy-up when he’s going every five days. Two impressive breaking balls in terms of spin and shape
I wonder how prevalent this preference to rising FAs is throughout MLB, and if any teams can fix the pitch shape.
