SAP Inside the Numbers is an ongoing series which looks to preview and reflect on the tour's major swings throughout the season. With the grass season in the books, SAP and WTA Insider dig deeper into the numbers to recap a dramatic grass-court swing, which saw former No.1 Angelique Kerber mow down the field to win Wimbledon for her third major title.
Wimbledon: Angelique Kerber d. Serena Williams, 6-3, 6-3.
Eastbourne: Caroline Wozniacki d. Aryna Sabalenka, 7–5, 7–6(5).
Birmingham: Petra Kvitova d. Magdalena Rybarikova, 4–6, 6–1, 6–2.
Nottingham: Ashleigh Barty d. Johanna Konta, 6–3, 3–6, 6–4.
Mallorca: Tatjana Maria d. Anastasija Sevastova, 6-4. 7-5.
Rosmalen: Aleksandra Krunic d. Kirsten Flipkens, 6-7 (0). 7-5. 6-1.
Sitting at a career-high ranking of No.16, Ashleigh Barty captured her second career title last month in Nottingham. Barty's grass-court prowess has been well-documented, having won the junior Wimbledon title at 15-years old in 2011. In her astounding comeback season last year, Barty made the biggest final of her career in Birmingham, losing to Petra Kvitova, and this year she won her first grass title by defeating Britain's Johanna Konta in the Nottingham final.
Wimbledon champion Kerber shrugged off a first-round loss in Mallorca to make the semifinals of Eastbourne, where she held match point against eventual champion Wozniacki, before rolling to her third major title at Wimbledon. Over the fortnight, Kerber lost just one set and knocked off a string of top-quality opposition in 2017 French Open champion Jelena Ostapenko, Indian Wells champion Naomi Osaka, Indian Wells runner-up Daria Kasatkina, former Eastbourne champion Belinda Bencic, and 7-time Wimbledon champion Serena Williams in the final.
With her win over Serena in the Wimbledon final, Kerber overtook No.8 Kvitova as the sole leader in match wins this season. Now ranked No.4, Kerber has made the quarterfinals or better at 10 of her 12 tournaments this year.
Germany's Julia Goerges was as surprised as anyone that her major breakthrough finally came on the grass at Wimbledon. The 29-year-old came into this year's edition of The Championships having lost in the first round in the last five years. But armed with her improved serve - Goerges tops the WTA Leaderboard in aces this year (304) - the Regensburg resident not only made the Quarterfinals at a Slam for the 1st time in her career, but she went one better by making her 1st Slam semifinal. En route to the semifinals, Goerges struck 47 aces, just one behind tournament leader Serena.
Kerber's 2018 rebound culminated in an exclamation mark at Wimbledon, but her improvements this season have been notable throughout the year on all surfaces. After finishing her astounding 2016 season as the WTA Year-End No.1 by winning her first two major titles at the Australian Open and US Open, Kerber struggled to build any momentum in 2017. The German began the year at No.1 and finished at a disappointing No.20. Across 22 tournaments in 2017. Kerber tallied just 1 Top 20 win. Through 12 events in 2018, she already has 12 Top 20 wins.
After turning the page on 2017 and bringing on veteran coach Wim Fissette, Kerber is not just back to her best - she's posting career-high numbers. As she proved in breaking Serena's serve 4 times in the Wimbledon final, Kerber's return game is back to being a dominant threat. During her 2017 slump, Kerber won just 31.8% of her return games compared to 46% this year, a career-best. Kerber is also hitting career-high numbers in first serve points won (66.1%), service points won (59.8%), return points won (48.5%), service games won (71.5%), and return games won (46%). For the 1st time in her career, she is also converting over half of her break point chances (50.8%).
