9 down: Orkney and Skye anew cursed the nine of diamonds? (3, 4, 7)
Answer: New York Yankees
The answer is an anagram of Orkney, Skye and anew.
The nine of diamonds is known as The Curse of Scotland but - apart from the fact that the baseball field is known as the diamond - there doesn't seem to be any connection with an American baseball team!
Apologies if this has already been queried.
