LONDON, Great Britain - Johanna Konta paired up with famed coach Wim Fissette at the start of the 2017 season and their already-successful season hit new heights when the British No.1 outlasted Simona Halep to reach her second Grand Slam semifinal - and her first at home - at Wimbledon.
"It's very special. Yesterday's match against Simona was incredible. Jo was playing on the Centre Court and both were at their best level. The atmosphere from the crowd was one of the best moments of my coaching career," Fissette told Nick McCarvel on the Wimbledon Channel.
Konta had never been past the second round at the All England Club, and has survived a trio of trilling matches against Donna Vekic, Caroline Garcia, and now Halep - who got within two points of becoming WTA World No.1 - to find herself in the semis, where she'll play Venus Williams for a spot in the final (Konta leads 3-2).
"I think she's winning a lot of matches with mental strength. That's a result of her hard work over the past years, to be able to stay strong in these situations. There were a few games in the Vekic match where she was 0-30 down, but she stayed strong and served well.
"I thought she was getting a little bit tired in yesterday's match - which was normal - but she got this amazing support from the crowd, which helped a lot."
Fissette has built a career working with elite athletes including Kim Clijsters, Sabine Lisicki, and Halep herself, coaching her through a breakthrough 2014 season that saw her reach her first Grand Slam final at Roland Garros.
"I know Simona well, but 2014 was a while ago. You still have to keep analyzing how her game has changed, so it's important to keep up with the latest matches."
The coach went to work, using every available resource to help his charge improve to 3-0 against the Romanian at tour-level matches - though Halep did beat Konta on clay in Fed Cup back in the spring.
"I watched a lot of videos and used the SAP stats we have available at the women's tour," he said, noting the use of SAP Tennis Analytics for Coaches. "I used as much information as I could to prepare her in the best possible way."
