Today is the deadline for players picked in the 2012 MLB First-Year Player Draft to sign, at 5 PM Eastern. Below the fold is a list of players drafted in the first through fifth rounds who haven't signed yet. Discuss the signing deadline in this thread. I will do my best to keep this updated through the day.
4----Baltimore Orioles: Kevin Gausman, RHP, LSU SIGNED FOR $4,320,000
8----Pittsburgh Pirates: Mark Appel, RHP, Stanford DID NOT SIGN
9----Miami Marlins: Andrew Heaney, LHP, Oklahoma State SIGNED FOR $2,600,000
16---Washington Nationals: Lucas Giolito, RHP, California HS SIGNED FOR $2,925,000
74---Oakland Athletics: Nolan Sanburn, RHP, SIGNED FOR $710,000
75---New York Mets: Teddy Stankiewicz, RHP, Texas HS DID NOT SIGN
95---Philadelphia Phillies: Alec Rash, RHP, Iowa HS DID NOT SIGN
104---Miami Marlins: Avery Romero, 3B, Florida HS SIGNED FOR $700,000
106---Oakland Athletics: Kyle Twomey, LHP, California HS DID NOT SIGN
136---Pittsburgh Pirates: Brandon Thomas, OF, Georgia Tech DID NOT SIGN
162---Baltimore Orioles: Colin Poche, LHP, Texas HS DID NOT SIGN
My guess is that everyone in the first and second rounds will sign except for Iowa high school pitcher Alec Rash.
