Federer had the early break at 2-0 but the 22-year-old Indian held his nerve and broke right back. With another solid game at 4-5, he converted his second break point to get the chance to serve out the set.

In the process, he became the first Indian to win a set against the 20-time Major winner.

But the 38-year-old – who had lost the first set he played at Wimbledon this year as well – bounced back in the next set and raced to a double break and levelled the match.
