The home team shall provide a ball which meets the specifications. The referee shall be the sole judge of the legality of the ball and may select a ball provided by the visiting team.

So, I'm assuming by warn down, you mean 1-12-1c wasn't met (deeply-pebbled cover).

Problem is, "deeply-pebbled" is subjective, and if the R says it's good enough, there won't be much you can do about it at the time.

Thanks Adam. Yeh - I would have argued the deeply-pebbled, had I known the rule.
