On Friday, the Royals signed Sean Manaea, Indiana State left-hander and 34th-overall pick in the recent MLB draft, to a $3.55 million signing bonus. That's a record for a supplemental-round choice and, as CBSSports.com's Jon Heyman points out, the highest dollar amount above draft slot for any 2013 signee.

Here's more from Heyman on Manaea:

Manaea was regarded as one of the top draft-eligible talents coming into 2013, but an inconsistent and injury-compromised junior season caused him to fall. The Royals, obviously, see the guy who lit up radar guns in the Cape Cod League last year, and they've paid him accordingly.
