I have noticed that many twitter posts about Petra Kvitová use the hashtag #P3tra.
What is origin of this hashtag? Is there some significance to this name (like 3 important wins or somethings similar)?
Petra Kvitová has a record of playing the biggest number of three-set matches, which is not something to be very proud of, I guess, but it has earned her the affectionate nickname “P3tra”.
