Brisbane: Roger Federer overcame a lingering sickness to hold off Grigor Dimitrov 6-4, 6-7 (4), 6-4 on Friday and take his title defense into the semifinals at the Brisbane International.
Federer delayed his opening match at the Australian Open warmup until the fifth day because of a flu-like illness and was playing Dimitrov in the quarterfinals on less than 24 hours rest.
By holding off Dimitrov, who is 10 years his
junior, Federer set up a meeting with 22-year-old Dominic Thiem, the youngest player in the top 20. (PTI)
