Roger Federer began his Wimbledon preparations with victory over Belarusian Ilya Ivashka in Halle.
In his first match since withdrawing midway through the French Open to protect his body, the Swiss was below his best but won 7-6 (7-4) 7-5.
The Halle Open in Germany, which Federer has won a record 10 times, is his fifth event this year as he returns following two knee surgeries in 2020.
It was his first match on grass since losing the 2019 Wimbledon final.
