US Open: Ons Jabeur beats Ajla Tomljanovic to reach semi-finals for first time

For the first time, the US Open semi-finals will feature a Croatian player.

The Tunisia, runner-up at Wimbledon in July, defeated Australia's Tomljanovic in a hard fought match.

In the Open era, she is the first African woman to reach the last four.

The 28-year-old will face either home favourite Coco Gauff or France'sCAROLINE GARCIA for a place in her second major final.

In her home country, she is known as the Minister of Happiness, and she looked down at herself against the in-form Tomljanovic.

She joked that she would be fired as Minister of Happiness.

I apologize for my actions.

The racquet kept slipping from my hands.

The fifth seed took the lead in the opening set with an outrageous volley that landed just on the baseline after a couple of break points.

After closing out the first set on a long Tomljanovic strike, Jabeur immediately broke to start the second, but neither player could get going.

There were at least six breaks of serve in the first nine games of the match.

She was jeered by the crowd when she threw her racquet to the ground, despite saving the set and forcing a tie-break.

She was able to find her serve when she was most in need.

She said that she knows that she has it in her to win a grand slam.
