Interference after being safe

[chuck chopper]

Rick, from what you described neither case had interference as no runners attempted to advance after the "wreck". So you two no calls seem correct. I don't know Federated rules, but ASA does not have a must slide rule and hopefully never will. But as already mentioned it seems you would have had to call interference in both cases should those other runners tried for another base. Runners who don't seem to have the ability to slide just waltz right on in and don't seem to think about the contact with the fielder.
