We don't know if analytics had anything to do with Cash's pre-determined decision.
We do know he did not allow much flex in the plan.
6 Ks in 6 PAs by the next 3 batters, surely points to the call for adjusting the plan, especially in a 1-0 game.
He'll never live down this call, which is too bad, because he must be a pretty good manager to get a team like his that far.
