On Monday our guest poster and stats lover Omair dug us into the numbers of his detailed analysis about the number of wins year-end Top 10 players scored over Top 10 players in 2011 and their best tournaments. Now it’s time for Part 2 and a different perspective – results of the Top 10 stars approached through their losses.
First have a look at the table showing average rank of players who defeated each of the year-end Top 10 players and the lowest-ranked player to beat year-end Top 10 players during 2011.
Vera Zvonareva needs to be mentioned here for her consistency as she is the only one of the Top 10 who was not beaten by a player ranked outside Top 35, while the rest of her colleagues from this elite group were beaten at least twice. The lowest-ranked player to defeat Zvonareva during 2011 was Tsvetana Pironkova, ranked 33rd (seeded 32nd) during the third round of Wimbledon.
Of Zvonareva’s 22 losses only three came at the hands of players ranked between 30 and 35 and interestingly they came at the hands of players ranked 31, 32, and 33. Also, a total of only three losses came at the hands of players ranked between 21 and 29, while the rest of 16 came at the hands of Top 20 players. Average rank of Zvonareva’s conquerors was 15, while the average rank of the conquerors of all the remaining Top 10 players was not even within Top 20.
Victoria Azarenka also needs to be mentioned here, because only five of her 17 losses came at the hands of players ranked outside Top 20, and of those five losses two came at the hands of Serena Williams who had low ranking due to her health problems and lack of play. Average rank of Azarenka’s conquerors in 2011 was 23.
Let’s continue with more specific tables, one for each of the Top 10 players, containing:
1) names of tournaments where players lost a match;
2) rank of the player that defeated them;
3) name of the player who defeated them.
Players who have beaten a Top 10 player in question twice or more in 2011 are highlighted in the tables.
Interestingly, three players have beaten Caroline Wozniacki twice this year, only one of them being a Top 10 player. Petra Kvitova has been beaten twice by only two players in 2011 – Andrea Petkovic and Vera Zvonareva – both the year-end Top 10 players. However, Petkovic was ranked 11th when she defeated Kvitova in Cincinnati.
It’s interesting to note that Kvitova, who can be considered the player of the year especially for her Wimbledon and WTA Championships titles, played two events on the ITF Women’s Circuit in 2011 – Nassau she exited in the opening round, while Prague 2 she lost in the final. Also note that six of Kvitova’s 13 losses (almost 50%) came at the hands of players ranked below 40.
SUMMARY STATS FOR WOZNIACKI
Total rank of players who defeated her: 465
Number of defeats: 17
Average rank: 27.4
SUMMARY STATS FOR KVITOVA
Total rank of players who defeated her: 474
Number of defeats: 13
Average rank: 36.5
Victoria Azarenka has been beaten twice or more by three players – Li (both times at Grand Slams), Kvitova (three times) and Serena Williams (twice). Maria Sharapova was beaten twice by two players – Kvitova and Li, both Top 10 players.
Flavia Pennetta needs to be mentioned here since she was the one who spoiled the perfect record of Sharapova in three-set matches during 2011. Before the US Open Sharapova had won all the matches during 2011 that went to the third set, however Pennetta changed all that at US Open when she beat Sharapova 6-3 3-6 6-4 in the third round of US Open.
SUMMARY STATS FOR AZARENKA
Total rank of players who defeated her: 398
Number of defeats: 17
Average rank: 23.4
SUMMARY STATS FOR SHARAPOVA
Total rank of players who defeated her: 603
Number of defeats: 14
Average rank: 43.1
Lisicki and Stosur have been able to defeat Li Na twice or more this year, with Stosur beating her on four ocassions. Samantha Stosur has been beaten by Sharapova (three times), Kirilenko (twice), Bartoli (twice) and Kvitova (twice).
Of all the Top 10 players, the US Open champion Stosur suffered the biggest loss in terms of how low her opponent was ranked, falling to No.262 Melinda Czink in the first round of Wimbledon.
SUMMARY STATS FOR LI
Total rank of players who defeated her: 624
Number of defeats: 17
Average rank: 36.7
SUMMARY STATS FOR STOSUR
Total rank of players who defeated her: 865
Number of defeats: 23
Average rank: 37.6
In the beginning of this analysis I’ve already said so much about Vera Zvonareva’s consistency, but there were two players against whom the Russian was weak: Agnieszka Radwanska defeated her four times in 2011, Samantha Stosur three times.
Agnieszka Radwanska also had her fair share of unwelcome opponents: Petra Cetkovska, Lucie Safarova, and Top 10 players Wozniacki and Kvitova all defeated Radwanska twice this year.
SUMMARY STATS FOR ZVONAREVA
Total rank of players who defeated her: 338
Number of defeats: 22
Average rank: 15.4
SUMMARY STATS FOR RADWANSKA
Total rank of players who defeated her: 453
Number of defeats: 18
Average rank: 25.2
Marion Bartoli has the unwelcome title in the elite 10, falling to the lowest-ranked opponents on average. Bartoli also has the unlikely honour of being the only Top 10 player who was beaten four times by players ranked outside Top 100 during 2011. However, she also played the most tournaments – 29, while no other Top 10 player played more than 22.
Andrea Petkovic and Caroline Wozniacki were the only players to beat Marion Bartoli twice or more this year. Wozniacki, Sharapova and Radwanska handed Andrea Petkovic two or more losses this year.
SUMMARY STATS FOR BARTOLI
Total rank of players who defeated her: 1310
Number of defeats: 25
Average rank: 52.4
SUMMARY STATS FOR PETKOVIC
Total rank of players who defeated her: 461
Number of defeats: 17
Average rank: 27.1
So far we’ve featured numerous Omair’s analytic tables covering the following topics:
- Comparative analysis of Top 10 players and their performance at big tournaments in 2011;
- Top 10 players in 2011 – how they scored against fellow big opponents; and now
- Top 10 players in 2011 – what do their losses suggest?
Did all these analyses help you draw some conclusions or direct your attention to specific data which you didn’t realize before? Did some specific numbers maybe only strengthen some of your theories about certain players? (photos: © Neal Trousdale)
