Open champion Padraig Harrington hopes a short break will boost his chances of reaching the FedExCup play-offs.
Harrington began well at the USPGA before fading
Harrington took time off ahead of this week's Barclays Classic in New York which builds up to the PGA Tour Championship in four weeks time.
"I've had eight days off which is the longest break I've ever taken in season," said the Irishman.
"It's probably the longest break I've ever taken without hitting a golf ball - I needed it."
Harrington claimed his first major title at last month's Open Championship in a playoff against Sergio Garcia.
But he admitted that the homecoming following his Open victory had taken a toll on his chances at the USPGA Championship.
Although he started with a one-under-par 69 he eventually fell back to finish tied for 42nd.
"Going home the following week, it was manic. There was so much happening, so much to do. It was very exciting, it was all go," said the 35-year-old Dubliner.
"I could see especially in Oklahoma where there was a definite fall-off with my concentration and my focus, I could see I was starting to lag a little bit. I was just starting to tire.
"I definitely needed a rest after the PGA, and I'm hoping that the swing is the same and I can just stay sharper mentally."
Harrington is one of 144 players who qualified for the first season-ending US Tour playoff series.
The field will be trimmed to 120 players for next week's Deutsche Bank Classic in Boston, and 70 players will compete in the BMW Championship in Chicago before 30 take part in the Tour Championship in Atlanta.
