(Reuters) - Roger Federer says he has seen "improvement and no setbacks" since returning to the Tour in March after over a year out due to two knee operations and with his grasscourt season kicking off in Halle next week, it's "go time".
Federer initially eyed a return at this year's Australian Open a year after exiting the 2020 Grand Slam at the semi-final stage, but slow progress in his recovery delayed his comeback.
