11 of Luke Donald's European Ryder Cup team are in action at this week's BMW PGA Championship.
It's the opening day of the DP World Golf Tour's flagship event, where Shane Lowry and Rory McIlroy are among the afternoon starters.
The Irish duo will have Spain's Jon Rahm for company, as they fine-tune their preparations for the Ryder Cup.
McIlroy won the Irish Open at the K Club last week and he says he's enjoyed being back in Europe:
Ryder Cup organisers have asked that Donald Trump does not arrive for the opening tee shots at Bethpage Black.
The US President will attend the first day of action at the New York course later this month.
But organisers are hoping he will choose to arrive for the afternoon session, rather than the morning foursomes.
Extra security measures due to Trump's attendance of tennis' US Open, led to the men's final being delayed significantly.
