Yahoo's Kendall Rogers has a nice rundown of the status of some top-level draftees heading into the signing deadline, including 6th Round pick Adam Plutko:
The Bruins also have their eyes on high school signees Adam Plutko and Zach Weiss. Plutko was a sixth-round selection of the Astros and Weiss a 10th-round pick by Pittsburgh. There’s a good chance both players go to college but it will be a long weekend in Westwood.
On 3rd Round pick Austin Wates:
Virginia Tech has its eyes on veterans Austin Wates and Jesse Hahn. Wates was a third-round pick of the Astros and he reportedly has been to Houston for a physical. Wates is expected to sign assuming he passes the physical.
We already know that Wates passed his physical, so expect an announcement soon, I guess.
