Day one digest: WGC FedEx St. Jude Invitational

Everything you need to know from day one at TPC Southwind.

Relentless Rahm, some inventive rescues and an unlikely autograph hunter stole the show as the WGC-FedEx St. Jude Invitational got under way on Thursday.

Here is everything you need to know from day one at TPC Southwind.

Relentless Rahm putts himself ahead

Jon Rahm revealed after his opening round that he had been so affected by jetlag heading to Memphis that he had not set foot on the front nine until he hit his tee shot on day one. You wouldn't have known it as the Spaniard equalled both the lowest opening round ever in a World Golf Championships event and his lowest round on the European Tour with a 62 that handed him a three shot lead. He made 142 feet and six inches of putts en route and admitted it was his approach play that allowed him to make up so many shots on the greens. "That was the key today, holing those putts," he said. "I managed to put the ball in positions where the putts didn't have much break."

When Poom met Tommy

They say you should never meet your heroes but if Poom Saksansin keeps up his form he could end up playing with his. The Thai is teeing it up this week thanks to his victory at the BNI Indonesian Masters where he held off a field including Henrik Stenson and Justin Rose to win the trophy. It was another Ryder Cup star he had his eye on in Memphis, though, as he admitted he was eager to get the autograph of Tommy Fleetwood and after play finished on Thursday, the Englishman duly obliged. The duo both finished day one on two under and if they match each other on day two, they could be signing cards rather than gloves together come the weekend.

Anything you can do

Ahead of The Open, Rahm admitted that while he would love to win the oldest Major like his countryman Seve Ballesteros, he did not think he could match the great man's swashbuckling, scrambling style. Well when he found himself in big trouble on the sixth on Thursday, the spirit of Seve was clearly there in his shot from the rough.

Recovery of the day, surely? Nope. Up steps Jordan Spieth.

Rory roars back

In the last four events where Rory McIlroy has missed the cut, he has gone on to finish first or second in three of his following appearances. That impressive comeback rate looked to be as good as gone as he sat three over after 12 holes at Southwind but he birdied the 14th, 15th, 16th and last to sit just seven shots off the lead. You can't keep a good man down.
