A few key points to note from the Mark Appel unveiling:
Jeff Luhnow (Loo-No) said the Appel signing was the "most significant investment the Astros have made" in an amateur player, and would not reveal the signing bonus.
Talks were ongoing with Boras, and the deal wasn't completed until today.
Appel will fly to Kisssimmee to work out and will make "several stops" through the minor-leagues. He is on an unknown innings limit, but Luhnow wants him to start at Tri-City and will be at Big League camp next Spring.
McTaggart said that finishing the 2013 season in Corpus is not out of the question.
Appel is "fully on board" with the organization's direction.
