Novak Djokovic made Grand Slam history at the age of 38 on Sunday with a commanding 6-3, 6-3, 6-2 victory over Jan-Lennard Struff, but the triumph came at a cost — his quarterfinal match falls on his daughter's birthday.

"Yeah, she was not very happy about it, me being absent from the birthday party. Don't remind me of that, please," said Djokovic, who became the oldest man to reach all four Grand Slam quarterfinals in a single season.

The victory also moved Djokovic into his 64th Grand Slam quarterfinal, extending his all-time record, while keeping alive his pursuit of a record 25th major title.
