So, NLDS with home field advantage for either series would have home games Friday 10/6, Saturday 10/7, and, if necessary, Thursday 10/12. We currently are 7.5 games up on the Cubs, 8 in the loss column, with the tie breaker.
Assuming Nats and Dodgers advance and the Dodgers have best record, we would have games Tuesday 10/17, Wednesday 10/18, and Thursday 10/19 if needed.
