Rory McIlroy might be the biggest fish on the Walker Cup panel - but he's a small fry it comes to shirt size.

Walker Cup shirt and sweater providers Glenmuir measured 20 of the 23 strong squad at Royal County Down this week.

But they can't find an 'Extra Small' shirt to fit McIlroy - the youngest player on the panel.

The Holywood ace will have to make do with a regular 'Small' instead.
