As part of the All Star Weekend in Atlanta, the MLB held its annual draft over Sunday Night and Monday. Several UNC players heard their name called, and overall there was very little drama about whether or not they would sign with their clubs.
A lot of this is because of how MLB has changed their signing structures for draftees, using a slotting system based on where they are drafted and making it pretty clear about what they would earn on the first deal for signing. Like any other sport, the earlier you are drafted, the higher the value.
