If we carry 13 into the playoff:
1. Rodon
2. Lynn
3. Giolito
4. Keuchel
5. Cease
6. Hendriks
7. Kimbrel
8. Kopech
9. Bummer
10. Crochet
11. Tepera
12. Lopez
13. Ruiz
Leaves 8 positional starters with Vaughn/Goodwin/Garcia/Hamilton/ Zavala off the bench.
I believe that's your playoff roster pretty much set if I didn't miss anyone. Its possible they go 3rd catcher over Ruiz
Poison pilling him + sheets to the Cubs would make some sense if they had anyone interesting. A veteran of makes the most sense ala Ian Happ but that would require Happ not to be absolutely awful and not a dfa candidate given hes arb eligible
It would have made sense at one point (still does from a tactical standpoint) but after the fake retirement we won't hear of Mercedes again I would think.
