Local Rule question

[chapmaja]

I had the following play a couple weeks ago.

R1 at 1b, B2 hits a ground ball to F4 who attempts to flip to F6 for a force. F6does not have her foott on the base, and as a result is forced to make a swipe tag attempt at R1's leg, which she tags just after R1's foot touches 2B.

This seems like a clear cut safe.

This is the league rule.

"On close plays at any base except first base, the runner shall slide or give themselves up. A player can be called out and even removed from the game if the umpire feels that the contact should have been avoided."
The bolded part is bolded in the rule.

Based on this rule, I call the runner out for not sliding.

It wasn't until today, looking for a weather related rule (after an issue last night) that I took a closer look at that rule.

The bolded part seems clear, but the unbolded part actually seems to add a lot of additional information to the rule.

I am not thinking I should not have called her out because the only contact was actually the tag being applied by the fielder. What say the forum. For the record, the offensive coach had no issue with the call and let his player know very clearly she should have slid.
