Red Sox sign Ty Buttrey. 1.3 million. Wonder where that money came from? Seniors in rounds 6-10. Now the attention is on Carson Fulmer. If Brian Johnson signs enough under slot, we can get him. Red Sox have signed everyone in top 10 rounds besides Deven Marrero, Brian Johnson, and Austin Maddox. Johnson and Maddox can't sign until their team is done with the college world series. So far it looks like the Red Sox got a pretty good haul.
