Jo Konta dug in deep to claim a semi-final spot in the Miami Open Premier Mandatory event in Florida overcoming the third seeded Simona Halep in three sets to become the first British woman to reach the last four in Miami.
I'm really happy that I've come through and I am just looking forward to my next round
From the opening moments, Halep looked to be well in control as he powered her way through the first set in keeping with her ranked status.
However Konta, the 10th seed, was not to be denied as she held on to fight back in the second. The tenacity of which the British No1 is now famous for, came to the fore as she broke Halep when the Romina was serving for the match and force a tie-breaker which went on to win 9-7.
Konta then went on to break Halep twice in te decidr to run out the 3-6 7-6(7) 6-2 victor and place in the last four where she meets Venus Williams who produced another surprise by toppling the world No1 Angelique Kerber.
"I’m really happy that I’ve come through and I am just looking forward to my next round – it’s going to be a tough one," Konta said no doubt expecting the German to be her next opponent.
Williams, at 36 the oldest woman in the field and a three-time former Miami champion, beat Kerber 7-5 6-3.
With the backing of a very vocal crowd to assist herm the American survived a nervy opening set but took control in the second.
"It was an interesting match. I was controlling it. I had more errors than I like and lower first serve percentage than I would like," said Williams. "I have to play well against the number one in the world. She’s on top of her game and she played well, so I had to find a way to play a little better," she added.
