Summers who gained a start in the event via Sectional Qualifying seven days ago was clearly delighted to be in the event. "How nice is it here," he said as he played in the stunning early morning conditions on day one of official practice.
It is the first major championship Summers will play having missed out on qualifying for the Open Championship by two shots on three occasions.
"While the main mission in coming to the US was to qualify for the US Open there was a full back option. You don't get a chance to play a major very often so you have to have a crack but if things had not worked out then we were going to play Pebble Beach, Spyglass and Spanish Bay with some mates. I do not have another event until August so there were a couple of months off anyway but Plan A worked out ok."
Today the New South Wales golfer had his coach John Serhan walking the fairways with him.
Summers' next significant tournament after this will not be until the Thailand Open on the OneAsia Tour but is clearly keen to take full advantage of what is a great opportunity he created for himself this week.
Jones hit only seven bunker shots in practice last week and was keen to get stuck into his preparation.
"I actually feel like I am hitting it very well and I like what I see of the golf course, said Jones. "They are not expecting any rain and that's where they can firm it up a bit. At present the fairways are soft enough you can keep the ball on them but if they do firm it up then you will be coming from the rough all the time. But coming from the fairways the golf course seems fairly generous."
Jones also qualified via Sectional Qualifying although his was in Japan.
