Former champion Daniil Medvedev survived a determined effort from 22-year-old Flavio Cobolli to reach the fourth round of the US Open on Saturday for the sixth straight year.

Russia’s Medvedev, seeded fifth, went down a break twice in the third set but recovered each time to triumph.

The Arthur Ashe Stadium crowd threw its support behind the 22-year-old Italian as he pushed Medvedev through a series of entertaining rallies.

But the experienced Medvedev with his uncanny defensive skills proved too much for the number 31 seed, lifting his level when it mattered most to deny Cobolli a first Grand Slam fourth round berth.

Medvedev won the last three games of the contest, sealing it on his second match point
