slow-pitch softball question

[relies77]

Ok guys, help me out here. I had a game on Wednesday and I was called out on a play where the third-baseman applied a tag while I was sliding into the base but then he LOST possession of the ball. It was not a force play, so that is not the issue. The issue here is that the third-baseman lost the ball. I know in baseball that a catcher needs to maintain possession of the ball after applying the tag. Does the same apply to slow-pitch softball? If you can, please direct me to the rule that would apply to this situation. Thanks!
