Wozniacki has only played one Grand slam in 2011, so don't read too much into those 2011 figures! Apart from that, the stats include all of Wozniackis grand slam matches except for 2008 for which I don't have complete stats. See my remark about this and a few other issues below. All stats are my own calculations but all figures are taken from the officiel match stats reports (once) available at the official grand slam sites like wimbledon.org etc.
A few important remarks:

1. Wozniacki played 14 Grand slam matches in 2008 but I only have full stats for 10 of those matches because she often played on smaller courts in 2008 where, say, winners and UE stats were not gathered. And I only have serve speed stats from 8 of her 14 matches in 2008 (no rader equipment on the smaller courts!).

2. Wozniacki's average serve speeds from 2008 may seem remarkably high, but the reason, I believe, is that there are serve measurements from all of her three French open matches, and only from five other GS matches that year. And since FO by far is the tournament where she has the fastest serves, her average speeds will be affected in an overly positive way.

3. A few stats in the table are presented as averages per match (for instance aces per match), but this is not an entirely useful approach. I'll explain why: Sometimes a player may play an almost infinetely long match - as was the case with the Isner/Mahut match in the men's singles at Wimbledon 2010. Both players hit more than 200 winners in that match, which would obviosly affect their overall 'winners per match' stats for 2010 in an unrealistic way! On other occasions players may play extremely short matches - like when Venus retired after 1 game in the 3rd round at Australian Open 2011. The best way to present the stats, therefore - in order to make them comparable from season to season - is to calculate them in respect to points played instead of matches played. Or even better: Aces as percentage per serve; DF's as percentage per serve (or as percentage per 2nd serve!); Winners as percentage per point played (or per point won!); UE's as percentage per point played (or even better: per point lost!). It's even possible to enhance and improve this suggested method to get an even better comparison, but maybe I'll come back to that. The table above will do for now.

4. The somewhat unusual statistic called "Risk of being broken" percentage is an estimate of how often a serve is broken. If a player has been serving 100 games, for instance, and has been broken 30 times, then her 'Risk of being broken' is 30 % (= 'games broken'/'games served' *100). It's not a statistic I've seen anywhere before, but it was suggested by another user here on tennisforum ("SamR03A"), and I found it quite clever and liked it!

Re: Caroline Wozniacki statistics

Thanks. Really good thread and post.

And yes - I've also often thought that when they publish things like Aces and matches played - those players who have had long matches get more chances to serve more Aces like you say.

That risk of being broken stat. Well it just felt in that last match I watched against Na from when she got broken after being 40-0 up that the risk was 100%. I know it wasn't quite - but that's what it felt to me. I see overall that it's up from last year and about the same as 2 years ago. I reckon that last match increased it though. I'd like to see that go down.

Re: Caroline Wozniacki statistics

Nice work, angliru. Of course as you pointed out the stats for 2011 are only for one slam but I would definitely like to see that % of second serves won be higher, at least over 50%.

terjw I agree completely about it seeming that Caroline % of being broken was 100%. When she was unable to win that one match point that she had I got a terrible feeling in my stomach and when she was broken twice to lose that second set I figured that she was done. It was frustrating because she was able to break Na Li so if she had been able to hold her serve she could have won that third set. Obviously no one is more aware of that than Caroline so she must realise that she needs to do better in the future and hopefully she will.

The Wta refers to "risk of being broken" as service games won, just fyi.

Re: Caroline Wozniacki statistics

It's actually the reverse (ie. service games lost), which means a lower percentage is better.

Re: Caroline Wozniacki statistics

This another angliru stats post, posted it so it didn't get lost in the rubble further down.

Wozniacki's first pro tournament (Cincinatti)


February 2006 - into top 1000!
An impressive performance at her 3rd pro tournament (Memphis) lifted Caro from well outside top 1000 into a position of approx. #461! Caro defeated K. Brandi and A. Harkleroad before losing to Sofia Arvidsson in QF. Arvidsson went on to win the tournament.


July 2007 - into top 100!
Caro progressed to 2nd round in Wimbledon - her 2nd GS tournament. Caro's performance lifted her from #103 to #88 in the rankings.


January 2008 - into top 50
Caro progressed to the 4th round in AO, which lifted her from # 64 to #45!


August 2008 - into top 20
Caro's second WTA title - in New Haven (unseeded!) - lifted her to #18 in the rankings.


May 2009 - into top 10!
Caro was runner up in Madrid (lost to Safina) and finally got the #10 spot in the rankings.


September 2009 - into top 5
Progressed to the final in the US open which lifted her to #6 in the rankings. A week later, Caro got the #5 spot when Kuznetsova fell from #4 to #6 after losing her points from Tokyo 2008.


February 2010 - #3!
Progressing to 4th round at AO (one round further than in 2009, when she lost to Dokic in 3rd) lifted Caro to #3 in the rankings.


March 2010 - #2!
Runner Up at Indian Wells lifted Caro to #2 in the world.


May 2010 - #3
Injuries and a poor performance in Madrid caused Caro to drop to #3.


June 2010 - #4
Wozniacki is not able to defend her 2009 Eastbourne title and drops to #4 in the rankings.


July 2010 - #3
Wozniacki reaches 4th round at Wimbledon which is equal to her 2009 performance. But Caro still rises to #3 in the world since Venus Williams has a poor Wimbledon and drops to #4.


August 2010 - #2
Caro is back at her career best #2 because Jankovic was unable to defend her 2009 title at Cincinnati.


October 2010 - #1
Serena Williams has not played a tournament since Wimbledon, so when Caro reached the QF at Beijing she overtook Serena's position as the new World No. 1. Caroline eventually won at Beijing. Prior to Beijing Caro has had two terrific months with tournament wins at Copenhagen, Montreal, New Haven, and Tokyo - and a SF at US Open!

Below is a graph of Caro's ranking progression compared with A. Radwanska's and Azarenka's rankings.

(EDIT: The reason I'm comparing Wozniacki with Azarenka and A. Radwanska is that I consider these three women the most talented player of the years 1989-1990. They all won Junior Grand slams (Vika and Aga two each), and at the year end Junior rankings 2005 they were ranked 1 (Vika), 2 (Aga), and 4 (Caro). More important though is that these are the only players of their generation who have been ranked in the top 10 (apart from the unfortunate and now retired Vaidisova). Because there are so many similarities between Aga, Caro, and Vika, it's obvious to compare them.

I like them all, and it's not my aim to prove who's better or more talented. They're all extremely talented, at no statistics can or should be used to prove othewise! But their careers may progress differently which the graph might indicate).



The graph is based upon the published ranking positions in Notes & Netcords from SEWTA's homepage. Those lists, of course, includes only top 100 rankings. The ranking positions outside of top 100 are based on the listed rankings in the player's h2h activies - also from SEWTA's homepage.


Wozniacki, A.Radwanska, & Azarenka ranking progression dates:

Re: Caroline Wozniacki statistics

I started the first 2 threads to keep track of her schedual in the "olden days" before Team Wozniacki posted the schedual at the season start, but they + the newer have a whole lot of info on points, money, games played etc mainly there so I can see what happened "last year" when looking at the next tournament.

Re: Caroline Wozniacki statistics

Great.

I've added yet another a statistics in my post #2 in the thread:

Code:
                              2008     2009     2010     2011

Serve points won %             60.5     58.5     58.5     59.2
It's often discussed whether a high 1st serve percentage and a lower "winning on first serve percentage" is preferable to a lower 1st serve percentage and a higher "winning on first serve percentage". The "serve points won" stats is the best way to determine this, as it shows the sum of 1st and 2nd serves won as a percentage of the total amount of serves.

Maybe I'll ad more stats in the future. Most of the data is already in the spreadsheet, so it's only a matter of writing a proper function to calculate just about any imaginable stats!

Year-end #1
Wozniacki is also the youngest year-end #1 since Hingis in 2000. Of the 36 year-end #1's in the open era, only 7 have been younger than Caroline (Graf twice, Seles twice, and Hingis three times). This is quite remarkable considering the changes in the age-eligibility rules.


Teenagers in the top 10
Wozniacki is the last WTA player who became a top 10 player as a teenager - at an age of 18 years, 10 months, 7 days. She achieved this 18th of May 2009. There had been 19 new teenagers in the top 10 in previous 11 years (which means a new teenager every 7th month) but noone since Wozniacki.


My last age-related statistic for now is regarding the age of the Grand slam finalists:



The average age of the last 22 Grand slam finalists is 26½ years! The only finalists under 23 years of age since Wimbledon 2008 are Safina (22 years and 9 months at AO 2009, and Wozniacki 19 years and 2 months at UO 2009).

Re: Caroline Wozniacki statistics

Someone posted career win/loss ratio vs. top 10 players in the statistics forum. There are just over 100 players in the original list. Here are the results for the present top 10 players:

Code:
Venus Williams			111	-	74		0.600
Kim Clijsters			 81	-	58		0.583
Caroline Wozniacki		 19	-	26		0.422
Na Li				 22	-	34		0.393
Victoria Azarenka		 18	-	28		0.391
Jelena Jankovic			 34	-	55		0.382
Agnieszka Radwanska		 12	-	31		0.279
Vera Zvonareva			 26	-	68		0.277
Francesca Schiavone		 25	-	72		0.258
Samantha Stosur			 12	-	38		0.240

Caroline is actually doing quite well. The problem for her with a statistic like this is that she's still very young, and has not has a lot of seasons to make up for her first few "not so good" seasons. Her stats are very lopsided:

Code:
Wozniacki 2006-2008               4     -       14              0.222
Wozniacki 2009-2011              15     -       12              0.556
The same can be said about other younger players like for instance Azarenka, who was 5-13 (0.278) until 2008, and 13-28 since then (0.464). Venus, by the way, had exactly the same career stats as Caro after 18 matches vs. top 10 players: 4 wins and 14 losses, and I don't think there's any evidence that Caro was particular bad in this respect early in her career (Ivanovic was 5-13, and Sharapova, who has some of the best overall stats against top 10 players, was 0-8 before she got her first win).

Re: Caroline Wozniacki statistics

Caro's W/L against top 10 players since she became a top 10 player herself: 13 - 7 (0.650)

Regarding Wozniacki the same can be said as regarding the previous stats: Her fist couple of years - though decent - seem to drag the stats down a bit:

Code:
Wozniacki 2007-2008           12       7      0.6316
Wozniacki 2009-2011           33       9      0.7857
