Owens Jabber put his ticket in the top 10 and advanced to the semi-finals of the WTA Indian Wells, which beat Annette Conteveit 7-5, 6-3 on Thursday.
Jubair has now won the Tour Leading 48 this season as she looks to win her second title of her career after winning the tournament in Birmingham earlier this year.
“My game hasn’t changed,” he said. “I want to play slice, drop shots and be good at forehand. I’m improving a lot of things.”
In the second quarterfinal on Thursday, Spain’s Paula Badusa attacked the top seed, defeating three-time Grand Slam champion Angelique Kerber 6-4, 7-5. Tunisia’s Jabir will face Badusa for a place in the final.
In the second semi-final, two-time winner Victoria Azarenka will face 24th seed Jelena Ostapenko.
Jubair’s victory is a guarantee that she will be in the top 10 in the world rankings for the first time in her career.
“It’s amazing. I’m working hard. At the end of last year I said I wanted to be in the top 10. People doubted me.”
The joint WTA and ATP Masters event usually takes place in March, but the global corona virus epidemic returned this autumn after a two-and-a-half year hiatus.
Jubair has now beaten Connaught three out of four in total, including a hard-fought victory at Cincinnati this summer.
Estonia’s Connaught took advantage of the loss and used it as a learning experience, winning 16 of their next 17 matches, including two titles for Cleveland and Ostrava, Czech Republic.
Jabbar got his first service break in the third game of his quarter-final to take a 2-1 lead. He broke the contest in the fifth and then in the 11th game to take a 6-5 lead and had a chance to complete the first set.
In the second set, the players remained in service until the seventh game when Jubair went 4-3. Xavier held the service and then broke the contest again to win 6-3 and win the match on the main stadium court.
Kerber had the most seeds left in the lottery after the troubles earlier this week. Its emission leaves Jubair at No. 12 as the highest seed.
Badusa closed the match with a 2-2 lead after winning the second set. But he rallied to win the last two games and make it to the semi-finals.
“It’s amazing,” he said. “I was terrified. He’s a three-time Grand Slam champion, so that means a lot to me.”
