So with the call up of Dan Strailey and Mike Olt, my need to own prospects is tearing me apart. In a 16 team dynasty league, my roster is as follows

C- AJ Pierzynski, D. Mesoraco

1B- Hosmer, Rizzo, LaRoche

2B- Kipnis

3B- Zimmerman

SS- Andrus

OF- Braun, Trout, Upton, D.Jennings, Wil Myers

SP- J.Weaver, S. Strasburg, M. Moore, H. Bailey, B. Colon, AJ Griffin, S.Miller, D. Bundy, A.Cashner

RP/P- K. Jansen, V. Pestano, C. Stammen, D. Robertson, S. Marshall, G. Perkins

I have acquired the 1st waiver and either the 1st or 2nd pick in next years draft.

I MUST have Oscar Tavares

Do I use my waiver on Olt or Strailey and hope like hell that OT doesn't get called up? Or do I hold my waiver just in case and then take him in the draft if necessary.

Also, I'm open to other suggestions for my roster, if you feel necessary.
