1 out, runners on second and third, potential walk off scenario. Ball to shortstop. Runners go. Tag is made on running running to third (2nd out). Then a failed play on the runner at home is made.
The batter thinks the game is over and doesn’t finish running to first. They are thrown out at first eventually (3rd out).
In a scenario with two outs and the put out on the B/R at first is made, it’s clearly no run scored.
In a situation where the third out is made on such, but on the same play as a relevant preceding out was a timing play on an elective runner, is there any exception? Or is this still no run, because the third out was a force/PO-on-BR-before-they-reached-first, even if the runner beat the second out (which was necessary to set up the third one ending the inning)?
