In our tournament championship game today we had an international tie breaker. In this overtime inning the visitor's last out is placed on 2B and the inning continues until 3 outs and then teams switch and home team puts last out on 2B and continue playing until 3 outs.

Does the Iscore software have a way for me to put a man on 2B? He would be the last out of the last inning. Please advise.

Welcome to the board.
To use tie breaker:
Misc.
Tie breaker
the last batted out automatically comes up.
If for whatever reason a different player is assigned second touch the second base at the tie breaker screen and change to the correct runner.
If you are already at the play screen after touching the tie breaker save, then touch the runner at second and assign a courtesy runner.

I ran into a situation where there was debate as to who the last batted out was if the last batter ended the inning with a fielders choice. Technically he wasn't put out. Hence the work around noted above.
