Dominika Cibulkova is competing in her first event since getting married two weeks ago to her longtime partner Michal Navara, on the day of the Wimbledon Ladies' final and the Slovakian number one is having a good summer of tennis so far and will be looking to carry on her momentum going into a busy period of the second half of the season.
Cibulkova played one of the matches of the year in the fourth round of Wimbledon against Agnieszka Radwanska and it was the duo's fourth three-set encounter of the year, Cibulkova should have won the match in straight sets and held match points but failed to convert them and she was match point down herself but won the match and had nothing left in the tank against an inspired Elena Vesnina in the quarterfinals.
Johanna Konta, the third seed is competing at the Bank of the West Classic for the first time in her career and after having a surprise run to the semifinals of the Australian Open and reaching the quarterfinals of the Miami Open, Konta's summer hasn't been what she had expected.
Konta crashed out in the first round of the French Open and the British number one won a singles match at Wimbledon for the first time in her career but she lost to Eugenie Bouchard in three sets, which was a tough second round match for the Brit.
How they got here
The 2013 champion seeded second received a bye in the first round and in her first competitive tennis match since getting married, Cibulkova won her second round match against Agnieszka Radwanska's younger sister Urszula 7-6, 6-3.
Cibulkova knew that a win in her quarterfinal match with Misaki Doi meant that she would return to the upper echelons of tennis by re-entering herself back into the top 10 for the first time since 2014.
The Slovak had a slow start as she has 2-5 down but she reeled off 11 consecutive games to win the match 7-5, 6-0 and back into the top 10 once again.
Konta also received a bye as the third seed and the Australian Open semifinalist recorded a straightforward 6-3, 6-1 over American wildcard Julia Boserup and in the quarterfinals Konta defeated Zheng Saisai to reach the semifinals in Stanford for the first time in her career.
The Brit is currently at a career high ranking of 17 and she could go even further if she wins the tournament by gaining a ranking of 14 which would be a remarkable achievement for Konta.
Their history
Cibulkova and Konta have met each other once and it was at the start of the year on the Australian hard courts of Hobart and the former Australian Open finalist Cibulkova was victorious in a tight encounter registering a 7-6, 7-5 win.
Who wins?
Both players are good hard court players and Konta's groundstrokes and serve work very well on a hard court and she could get Cibulkova in uncomfortable position, however, Cibulkova can outlast Konta if they engage in long rallies and although Cibulkova could be overpowered by the Brit she could use her blistering forehand to get her out of trouble.
The duo will be playing at the Rogers Cup in Montreal and the Olympics in Rio and the US Open, so it is going to be a busy summer for both players and if one of these players could win the title here it would build some momentum and give them a load of confidence.
Cibulkova could rise to a career high ranking of nine in the world if she reaches the final, which would be impressive for the Slovak as she suffered from a loss of form and had surgery on an Achilles which meant that Cibulkova was unseeded at a lot of the big events and had tough draws.
The winner of this match will play top seed and former two-time champion Venus Williams or Alison Riske in the final.
This semifinal match will take place on the Stadium court at 2pm local time.
Prediction: Cibulkova in three sets.
