It's this article, isn't it? http://ftw.usatoday.com/2015/01/caroline-wozniacki-australian-open-victoria-azarenka-seeding I understand "Wozniacki got jobbed" to mean she was treated unfairly. A job was done on her. This is a colloquial phrase: to do a job on someone/something. "A long holdout" refers to the Wimbledon matches; several rounds are played before well-known or high-ranking players are put in the same match. So the tennis fans have to wait until they see a match that would get them really excited. Look up the phrase "to hold out on someone" and you'll have an idea of what "a holdout" would mean. The last sentence is correct, and we read it like this: "The idea that [Diyas and Dellacqua are seeded but Victoria Azarenka isn’t (seeded)] is preposterous. It's laughable." So, the writer has omitted a redundant word. We would add a brief pause between "isn't" and "is" if we were reading aloud.

but Victoria Azarenka isn’t is preposterous.it's laughable. We are seeing an example of very a very badly constructed English sentence. The "isn't is" construction, using the double verb is very confusing indeed. This can be avoided by changing the compound sentence to two simpler sentences. Here is how: "The idea that Diyas and Dellacqua are seeded but Victoria Azarenka isn’t is preposterous.it's laughable.: (Let's change it to...) "Diyas and Dellacqua are seeded. It is preposterous and laugable that Victoria Azarenka is not seeded." .

D & D are "seeded" but Victoria Azarenka is not seeded. D & D are regarded as top contenders in some competition, but VA is not regarded as a top contender. D & D are seeded. VA isn't seeded.

What "got jobbed" means? Here, the reference, though vague, refers to a sporting event. "Got jobbed" is not specific. It basically means that somebody "did" something to Wozniacki. It can mean beaten fairly or unfairly. It can mean that Woznicaki had a low score, or that some minor rules violation caused Wozniaki to suffer a loss in score. It could mean that some fan or another player said something to distract or interfere with Wozniacki. Getting "jobbed" just means that some overwhelming event occurred which caused Woz to perform or finish poorly. Long Holdout = The reference here is vague also. It basically means that a person refused to do something. Long, means that the person has refused to do something for a "long time". For example, a chess player might refuse to play a champion for several years. That would make that player a "long holdout".
