Roger Federer has overcome seven match points in the Australian Open quarterfinals to turn things around and edge Tennys Sandgren of the United States in five sets.
The 100th-ranked Sandgren had three chances at the biggest victory of his career at 5-4 in the fourth set and another four in the ensuing tiebreaker. But he was unable to convert any of those.
The 38-year-old Federer somehow pulled out that tiebreaker against the man who is 10 years his junior to extend the match and then was better in the fifth.
Federer took a medical timeout for treatment from a trainer in the third set and had an argument with the chair umpire after being penalized for cursing.
