No. 249 - Tyler Heineman (C) - UCLA

No. 429 - Joe Sciafani (SS) - Dartmouth
No. 459 - Erick Gonzalez (RHP) - Gateway CC (Ariz.)
For many teams, the later rounds on Tuesday were full of college players, as teams went after players more likely to sign. As a result, some talented high school players have fallen, making it more likely they head to school.
