Emma Raducanu cruised through to the third round of the US Open with a thumping 6-2 6-1 win over Janice Tjen on Wednesday.

The 2021 champion needed only 62 minutes on court for her opening win over Ena Shibahara, and she was in a rush once more on Louis Armstrong Stadium, her straight-sets victory this time two minutes quicker at precisely an hour.

Raducanu broke immediately to build a 3-0 lead in the opening set, albeit she had to save three break points from her Indonesian opponent in the third game.

The British No 1 was near faultless thereafter, breaking Tjen again to wrap up the first set 6-2, before racing into a 5-0 lead in the second.

Tjen would get one more game on the board, before Raducanu served things out for a comprehensive victory.

The 22-year-old's serve was a particular highlight throughout the match, with eight aces across the contest and 76 per cent of points won on her first serve.

There will admittedly be tougher tests ahead for Raducanu, with Shibahara (128th) and Tjen (149th) both qualifiers and ranked outside the world's top 100.

She could face ninth seed - and 2022 Wimbledon champion - Elena Rybakina in the next round, with the Kazakh first facing Czech qualifier Tereza Valentova in the second round.
