World number two Ashleigh Barty battled back from a set down to reach the US Open second round with victory over Kazakhstan’s Zarina Diyas.

Barty, 23, wrapped up a 1-6 6-3 6-2 win over Diyas in one hour 43 minutes.

The Australian will play American Lauren Davis or Sweden’s Johanna Larsson in the next round in New York.

World number three Karolina Pliskova is also through following a topsy-turvy straight-set victory over Czech compatriot Tereza Martincova.

Pliskova beat Martincova 7-6 (8-6) 7-6 (7-3) in a match that saw 12 breaks of serve, excluding both tie-breaks.

The 27-year-old, who reached the final at Flushing Meadows in 2016, will play Mariam Bolkvadze or Bernarda Pera next.

“It’s tough to play Tereza,” Pliskova said. “Especially in the first round.

“It was not my best performance today for sure, and she made some great shots.”
