LONDON — After pulling off one of the biggest wins of his career, Alexander Zverev was left apologizing for an unforced error he didn’t make.
Zverev denied Roger Federer a shot at a 100th career title by beating the Swiss great 7-5, 7-6 (5) on Saturday to advance to the championship match at the ATP Finals.
Federer was leading the second-set tiebreaker 4-3 and in the ascendancy of a rally on a Zverev service point when a ball boy at the back of the court dropped a ball. Zverev immediately signaled for the point to be stopped and the umpire ordered the point to be replayed.
