Roger Federer's early exit from Cincinnati has prompted a simple plan for his US Open preparation.

The 20-time Grand Slam champion said he will take a few days off then train in New York for the season's final Grand Slam.

"I mean, look, also very important for me is always to see that I'm injury-free and I'm feeling good," Federer said after his 6-3, 6-4 Western & Southern Open loss to Andrey Rublev. "Regardless of what the outcome of this week, I'm happy I came here, had good practice sessions.

"Look, I had two matches here and hoped it would have gone better. But the plan is always not to lose first round. The plan is always not to lose second round. The plan is never really to be in the weekend. It's trying to be there."

The 38-year-old Swiss said he feels no scar tissue after holding a pair of championship points in the Wimbledon final before bowing to world No. 1 Novak Djokovic in a gut-wrenching loss.

Federer plans to "keep it simple" during his practice sessions in Flushing Meadows next week.

"I will have a few more days off now, I'm sure, before the US Open," Federer said. "I worked very hard coming into Cincinnati, you know, and sort of in that little season we had since Wimbledon, so I can maybe also utilize a couple of days off. I'm going to train, exactly what I need to do for the Open, and that's it. It's fairly simple, keep it simple, but I've got to work hard."
