Well, almost unassisted. How to score? Runner on 1st, less than 2 out. Medium grounder up middle fielded by second baseman who steps on second (out number one, unassisted putout by 4), then throws to 1st ( out number 2, assist by 4, putout by 3). Double play

Out
Ground out
Location of ball
4-3
Then what happened to runner on first
out, second base, double play

This is a very standard play, score as you see it...

In play
Out
Ground out
Set location...
What happens to runner at first? Out
fielders involved? 4-3 done ( you can also do 4-4-3 if you like, same stat effect)
What happen to batter? Out double play

Score card, shows
B1- 1st out, FO2 at 2nd (force out batter 2)
B2 -2nd out, 4-4-3 double play

Stats
Second basemen, gets a put out and an assist
First baseman gets a put out


There is also a quick out shortcut, for when you get more experienced, flick the out button, see quick play options, in this case 4-3 ... Location, what happen to runner at first? Out double play!

Perfect. Was my mistake. I thought I wasn't getting the putout stat for second baseman. Double checked. All good. I scored it as you did, though the 4-4-3 idea is interesting (tho I opted against it)
