Did I Make The Right Call?

[fastpitch]

I had a similar situation in a PeeWee 8U game a month ago where tensions were high with the top 2 teams in the league playing. R2 was running between 2nd and 3rd near the outfield grass when she was struck by the ball with no fielders near to make a play on the ball. I did not call her out and 2 runs scored to end the game. It would have been easy to make the call and no arguments would have ensued - as it was the winners were happy but everyone thought we got the call wrong. I've heard it argued that any fielder can make a play like a RF to 1B out but don't think I'd make that call. If an infielder had been anywhere near her I'd have made the out call.
