question for woodrow in particular(since i understand youīre a professional umpire)
when i play on clay, do i need to be able to show a clear mark if i call a ball out?
problem 1, sometimes on wet courts itīs difficult to see a clear mark
problem 2, once i look away from the mark, i might not be able to find it again with certainty. in situations when i donīt expect the call to be challenged in the first place that can happen.
