Federer suffers brutal collapse in Qatar Open loss
Meanwhile, Roger Federer's hopes of winning a fourth title in Qatar have been dashed after his quarter-final exit but the Swiss said his first event after two knee surgeries was just a "stepping stone" as he targeted full fitness for the grasscourt season.
Federer took the opening set against Nikoloz Basilashvili on Thursday before the Georgian fought back from a match point down in the final set to win 3-6 6-1 7-5, ending the 39-year-old's challenge in his first event in 14 months.
"I'm actually happy that I was able to play back-to-back three-set matches against top players. That's an important step forward to me," Federer, who beat Dan Evans in the last-16, told reporters.
"I'm not 100% yet. I can feel it, I can see it. From that standpoint, (what's) important is to be 100% by the grasscourt season... I'm still building up.
"So this is a stepping stone. I'm actually happy how I felt today on court overall.
"I was very happy with how I was able to handle the tough moments. I didn't feel like my game started to wobble the more important the points got.
"I think I was able to play how I wanted to play, so I think that's always a great sign and a great feeling to have."
