Rule 5 eligible; the plan leaves him unprotected on Nov 17.

Rule 5 pick risk 0.21 (the plan’s ordering, not a probability); expected loss if exposed 0.01 WAR.

Rule 5 protectiondue Nov 17 · medium confidence
Protect Termarr Johnson (2B, AAA, FV 45), Derek Diamond (SIRP, AAA, FV 40) and Keiner Delgado (SS, AA, FV 40) by Nov 17. Expose the rest; the most likely to be taken is Cy Nielson (AAA, risk 0.23; expected loss 0.03 long-term WAR, below the 0.06 that cutting Noah Murdock for a fourth spot would cost; the plan's rule protects at most three).
