In the out section of the batter, you have ground out, line drive out pop/fly out; but what about adding a foulout feature?
Scorecard could read it as (example: Batter fouled out to third base; scorecard could read 5F)

A foul out is just a pop out or fly out with a hit location in foul territory. It is not a separate statistic / indication.
