Cincinnati – Roger Federer remains determined to enter US Open at full throttle, though suffering a 6-3, 6-4 Thursday's loss to Thursday Andrey Rublev at the ATP Cincinnati Masters.
The 70th-ranked Russian qualifier was still in awe after knocking out the seven-time winner of the tournament in 61 minutes – the fastest loss for the 38-year-old Swiss since 2003 in Sydney when he fell in 54 minutes.
But with the wisdom gained from nearly two decades of touring, the 20-time Grand Slam winner was hardly at the panic stations after the surprising defeat.
"It's very important to me that I'm injury-free and feel good," he said.
"No matter what the outcome of this week is, I am happy to have come here and had good practice sessions.
"I had two games here and I hoped it would have worked out better – the plan is always not to lose the first round. The plan is always not to lose the second round.
"In fact, the plan is never over the weekend. He's trying to be there.
"When such results happen, you move away from him and say, 'What is the plan? "I don't know. I just got off the court."
Federer said discussions with his team will determine his schedule for the remainder of this week and next, with the final Grand Slam of the season beginning Monday.
"I'll have a few more days off now, I'm sure before the US Open," he said.
"I worked really hard, going into Cincinnati that little season we had from Wimbledon.
"I'll train – just what I have to do for the Open – and that's it. It's pretty simple, keep it simple, but I have to work hard."
Federer won his last Cincinnati title in 2015, making a career-high 47-10 at the event.
He first played 21-year-old Rublev.
