Each day of Wimbledon, Baseline will sum up the action with a photo gallery of the top surprises.

The Strycova Show

After 16 years on tour, 33-year-old Barbora Strycova has reached her first career Grand Slam semifinal. The Czech bested Great Britain's greatest hope Johanna Konta, 7-6 (5), 6-1. Strycova is more well-known for her doubles skills; she's currently ranked No. 3 and into the doubles quarterfinals with Hsieh Su-wei. Strycova has been in five doubles major semifinals.

Riske's Run Ends

With their first career meeting against each other coming as a quarterfinal on Centre Court, the tension was high. Serena Williams survived Alison Riske's onslaught to win, 6-4, 4-6, 6-3. Riske has been nearly unbeatable on grass this season, picking up two titles and piling together a 14-2 record. She leaves the All England Club as a member of the Last Eight club for the first time.

Serena's Fine

Speaking of Serena, the 23-time Grand Slam champion was handed a $10,000 fine for unsportsmanlike conduct for her actions before the tournament. Wimbledon is very particular about its grass-court conditions, and they fined Serena for damaging the court.

"I just threw my racquet. I got fined," Serena said. "I mean, I guess if you could tell me, I would appreciate it. I mean, I have always been an Avenger in my heart. Maybe I'm super strong, I don't know."

Svitolina Soars

Surprisingly, it's Elina Svitolina's first time in a Grand Slam semifinal. She had reached four quarterfinals previously and has been as high as No. 3 in the world, but couldn't quite get past the hurdle. On Tuesday, she took out unseeded Karolina Muchova, 7-5, 6-4 to set up a showdown with Simona Halep.

"It feels amazing," Svitolina said. "But I try to don't think so much about it any more as I was trying to not think so much about that I couldn't get the win before in quarterfinals."

"MuRena" Move On

The dream team of Serena Williams and Andy Murray won again on Tuesday with a 7-5, 6-3 win over Raquel Atawo and Fabrice Martin. Serena stepped up in both the serve and return categories to help carry "MuRena" to the round of 16.

The BBC asked Murray if their team name is Serena's preferred choice of "MuRena" instead of "SerAndy" and he quickly said: "I think Serena's the boss, so whatever she says goes."
