US Open 2016: Kyle Edmund through to US Open third round

Edmund's previous best was two second round appearances at the French Open

Britain's Kyle Edmund beat American wildcard Ernesto Escobedo at the US Open to reach the third round of a Grand Slam for the first time.

Edmund, 21, followed up his first-round win over 13th seed Richard Gasquet with another confident display as he came through 7-5 6-4 6-4.

The Yorkshireman, ranked 84th in the world, will play American 20th seed John Isner in the last 32.

Briton Johanna Konta beat Bulgarian Tsvetana Pironkova 6-2 5-7 6-2.

But she needed to overcome a health scare when she started suffering with breathing problems towards the end of the second set.

Compatriots Andy Murray, Dan Evans and Naomi Broady play their second-round matches on Thursday.

Edmund looked to have been handed a golden opportunity facing Escobedo in the second round, but the world number 201 made him work for victory.

With both men struggling to find their first serve, Edmund edged the first set but saw six break points slip by in the second.

Escobedo had claimed his first Tour-level win in the first round

He earned a seventh chance with some brilliant defence and eventually secured a two-set lead after an hour and a half.

He sealed victory by breaking in the ninth game of the third set and then confidently holding serve.

"A lot of things went better for me against Gasquet," Edmund told Eurosport. "This was about toughing out more longer rallies."
