John Sickels over at the great Minor League Ball has posted his top 20 prospects for the Giants. The list is a fun read for anyone interested in the Giants farm system. A few surprises, I was surprised to see Marcus Sanders get a B rating after a disappointing 2006. Sickels does state that he only gives Sanders a B if his struggles were the result of his shoulder problem. Of course Timmy is #1 and one of the few glimmers of hope in a otherwise underwhelming farm system.
