I happen to live 10 minutes away from where Walker Jenkins plays HS ball. Went to a couple games, first HS BB games I have watched in eons.
Huge crowd. At least 10 video cameras set up behind the plate. Allegedly several pro scouts in attendance.
Walker is a man amongst boys at this stage. Tall, rangy kid with a sweet left handed swing. Moves well, glides around the outfield and good, not great, arm based on watching warmup throws.
Hitting, tough to judge as they wont pitch to him. Opposing pitchers get fired up and throw as hard as they can, and then come nowhere near the strike zone.
He gets jeered by the opposing fans, too. Part of that may be due to the shocking neon orange cleats he wears!
I have no idea how you can possibly project a young man like this. He looks terrific, but he is playing so far below his level that it is all guesswork. I guess that is why scouts and FO people make the big bucks.....
Me, I would prefer drafting a more sure-fire college prospect, but I would take a conservative approach with the 5th overall pick.
