NEW YORK (Reuters) - Daniil Medvedev fired off 13 aces to end British hope Dan Evans' U.S. Open challenge with a quickfire 6-3 6-4 6-3 victory in the fourth round on Sunday.

Evans had survived a fifth set tiebreak against Alexei Popyrin to reach the last 16 but on day seven of the hardcourt major, he was no match for the Russian second seed.
