Not entirely unexpected. Here's the news release from the Astros:
HOUSTON, TX - The Houston Astros have announced that they will sign right-handed pitcher Mark Appel, who was selected with the first overall pick in the 2013 MLB First-Year Player Draft, to a contract this afternoon. Terms of the deal were not disclosed. The announcement was made by Astros Director of Amateur Scouting Mike Elias.
Appel, Elias, Astros General Manager Jeff Luhnow and Appel’s agent, Scott Boras, will be available to the media TODAY at 3 p.m. in Minute Maid Park’s press conference room.
Mark Appel is the 23rd player drafted by the Astros to sign and the seventh out of the top 10 rounds. Several national media have said the Appel's signing bonus is in the $6.3M range, which is what Jim Callis of Baseball America reported several days ago.
