2 different situations

[bigdog]

1. Game last night. Player enters game in 3rd inning but doesn't report. Bats and strikes out in the top of 4th.In the sixth inning she bats again and hits a double.Opposing team calls time and tells ump she is unreported sub umpire checks his card and call her out for not reporting. What is the rule as a rule book around here is hard to find?

2.Runner between 2nd and 3rd interferes with shortstop fielding a ground ball. They call runner out but allow run to score. I know the rule in baseball but homeplate ump said rule was different in high school softball.
