Davies has slipped from his place inside golf's top 50 in the world
Rhys Davies' Ryder Cup dream is all but over as the Welshman has withdrawn from this week's Czech Open with fatigue.
The 25-year-old, bidding to star at his home Ryder Cup in Wales in October, can no longer make the Ryder Cup on points.
And a pick from Europe captain Colin Montgomerie looks unlikely as Padraig Harrington, Justin Rose and Luke Donald all require a wild card to play.
"Important though the Ryder Cup is, to me it's not the goal," said Davies. "Winning tournaments is."
Davies, in his first full year on the European Tour, finished just 62nd at the weekend's USPGA Championship at Whistling Straits in the final major of the year.
The Welshman was runner-up to Graeme McDowell, who went on to win the US Open, on the Ryder Cup course at the Celtic Manor in Newport in the Wales Open in June and closed with a record nine-under-par round 62.
The European Tour rookie also won in Morocco in March and is 17th in the race for places.
I said at the start of the week I would listen to my body and my body is telling me to take a rest
There are sufficient points in the last two events for him to climb into the top nine to be an automatic selection but Davies does not feel it right to push himself over the limit.
"I said at the start of the week I would listen to my body and my body is telling me to take a rest," he said.
"It's been a hectic schedule and it's probably catching up with me.
"I played well for 52 holes and was four under, but then I finished in a train wreck."
Davies suffered had a quadruple-bogey eight on the 18th at the end of his third round at the USPGA Championship and then added another 75 in his final round on the banks of Lake Michigan.
The 2003 British Boys champion, acknowledged by Montgomerie and others as one of the best putters in the game, is entered for the race-ending Johnnie Walker Championship at Gleneagles next week, where a win would advance his claims for a pick against some stiff competition.
Three-time major winner Harrington and English pair Rose and Donald boast vast Ryder Cup experience and are all inside the top 25 in the world.
And Davies, whose world ranking is 52, has always remained pragmatic on his chances of making Montgomerie's European team despite the romantic notion of a Welshman playing in Wales' first Ryder Cup.
"I know it's an attention and something that people may expect," Davies said in June.
"But at the start of the year it was so far out of reach that it was never a thought - and it remains that way."
