Jigjag,
You picked the wrong 'earlier in the week' clue! It was on Wednesday - Brilliant rescue dog detailed to enter cricket club (7).
I swept past the cricket stuff, I was busy musing over 'detailed'. I used to think it was clever, now I think it's in danger of being over-used.
'Ump' seems a very ungainly, inelegant word. I've never heard it used in relation to tennis, thank goodness.
