LONDON, Great Britain - The Wimbledon semifinals are set for Thursday, pitting five-time champion Venus Williams against Britain's history-making Johanna Konta, and 2015 finalist Garbiñe Muguruza against the lawnmowing game of Magdalena Rybarikova.
For Konta and Venus, the match-up pits the two most efficient servers of the tournament against each other. Both women lead the remaining field in unreturned first serves, unreturned second serves, aces, and first serve points won. Given their powerful serves and small margins, it's not surprising that they also lead the field in double-faults, with Venus striking 24 and Konta at 10 (Muguruza and Rybarikova combine for 10 double-faults).
Max Serve Speed
Unreturned 1st Serve (Tournament Avg: 29%)
Unreturned 2nd Serve (Avg: 18%)
Despite their big serves, Konta and Venus trail Muguruza when it comes to efficiency in holding serve. The Spaniard has been broken just four times all tournament -- three of those breaks came at the hands of No.1 Angelique Kerber -- as Muguruza has won 47 of her 51 service games (92%) over the fortnight. The key to Muguruza's serving success? She's been incredibly clutch.
1st Serves In (Avg: 63%)
1st Serve Points Won (Avg: 66%)
2nd Serve Points Won (Avg: 47%)
Break Points Saved (Avg: 56%)
Service Games Won (Avg: 70%)
Muguruza has saved 17 of the 21 break points she's faced, putting her in the lead at 81% of break points saved. Venus is right behind her at 73%, Konta at 69%, with Rybarikova having faced the most break points of the four (32) and saving 59% of them. On return, the Spaniard has been solid, converting 49% of her break point chances and breaking in 34% of her return games.
Rybarikova may trail in nearly all service categories, but it's in the return game that her game shines. The Slovakian, who defeated CoCo Vandeweghe to become the first Slovakian to ever advance to the Wimbledon semifinals, leads the remaining field in return points won against first serve and second serve.
Returns In Play (Avg: 75%)
Return Points Won vs. 1st Serve (Avg: 34%)
Return Points Won vs. 2nd Serve (Avg: 53%)
Break Points Won (Avg: 44%)
Return Games Won (Avg: 30%)
She is the only semifinalist to convert over half of her break point chances (25 of 47), and has won nearly 50% of her return games, converting 25 of 52 games. In contrast, Konta and Venus are below 30% in return games won, with Konta bottoming out the four at 24%, breaking in 17 of 70 return games.
Also of note: Konta has played two of the five longest matches of the tournament. Her 3 hour and 10 minute thriller against Donna Vekic in the second round is the longest women's match of the tournament, and her quarterfinal against Simona Halep, which lasted 2 hours and 38 minutes, also landed in the top five longest matches so far.
