Great Britain and Ireland captain Nigel Edwards will be in the US when the Walker Cup team is officially announced on August 24.

That's the day after the US Amateur Championship at Olympia Fields in the Chicago suburbs, where Gary Hurley, Paul Dunne and Cormac Sharvin will be bidding to confirm their expected selection with solid performances.

In what is now an example of the stark reality of the modern amateur game, it is at a USGA event on a parkland course rather than a GB& I event on a links that the final decisions will be made.

But that's not to say that this week's Home Internationals, which begin at Royal Portrush today, will not have a bearing on the final decision of Edwards and the selectors.

Ireland defend the Raymond Trophy with five new caps — The Island's Paul McBride, Castle's Alex Gleeson, Knock's Colin Fairweather, Hermitage's Rowan Lester and Tullamore's Stuart Grehan.

But from a Walker Cup perspective, all eyes may well be on the performances of Naas' Jack Hume, who is believed by man to have an excellent chance of selection for Royal Lytham and St Annes next month.

With the strength of the Dunne-Hurley partnership already well known — they've dropped just half a point in their last nine matches together — Hume can strengthen his hand by showing his good understanding with 2013 Walker Cup player Gavin Moynihan alongside when they take on England's Ben Taylor and Tomasz Anderson in the opening foursomes.

That Hume is pitted against Jimmy Mullen at No 1 in the singles is also fascinating and perhaps an indicator of the battle for places in Edwards' 10-man side to face the USA from September 12-13.
