Muguruza has not won a title since claiming her only major at the French Open a year ago, but is hoping the addition of 1994 Wimbledon champion Martinez to her coaching team at SW19 can help her see off Venus Williams or Johanna Konta.
The American, who has dropped only one set all tournament, was too strong for her opponent from the baseline and was able to produce booming serves whenever Konta threatened.
"It was very hard for me to get a good foothold in the match". I would have liked to have made it a full fortnight but it's okay. "I think today it came down on the day, and Venus played better than me". "She was talking to her all the time", Kuznetsova said. "Honestly, they were just cheering for me". The crowd were so fair, I know they love Jo.
For Williams, it'll be the 22nd Grand Slam semifinal of her career.
These aren't no-names in Friday's men's semifinals, far from it, but it's the first time since 2003 that all four players in a Grand Slam semifinal are outside the top four in world rankings.
A month after suffering a humbling loss to Australian Ashleigh Barty in Birmingham, Muguruza credits the addition of 1994 Wimbledon champion Conchita Martinez to her coaching team for providing a new-found calm and confidence.

In recent years Williams, 37, has usually spent most of the fortnight answering questions about when she may retire, especially following her diagnosis with Sjögren's syndrome, an autoimmune disease which causes fatigue, muscle and joint pain.
But Williams, who came into the tournament emotionally drained after being involved in a fatal vehicle accident in Florida last month, methodically doused the hysteria. "Before the match I wished she could do it for me, but I said "no you have to do it for yourself", Venus said. Her finals appearance in 2015 was her only time seeing the Wimbledon final previously.
It's safe to say that Garbine Muguruza will face a stiffer challenge fromVenus Williams in the Wimbledon women's final than the Spaniard did in Thursday's semifinal.
"Even we had some very good rallies, but I was, like, sometimes I could not believe".
"She showed a lot of courage, played in tough situations against players who were in form".
"I miss her so much".
