Surely, she was also lucky with the draw not to play more than one seeded player throughout the tournament, but what's important is that she made the most of it. With this confidence I'm sure only exhaustion can stand in her way next week.
One more thing, next week tournament is on clay, transition from hard surface to clay is always tough.
In addition to exhaustion and the transition to clay, Jelena might also have to deal with a much tougher draw next week.
Not to take anything away from her amazing accomplishment but she had a fairly easy route to the title this week. As ma re said, she played against only one seeded player--and it was the #9 seed at that.
Next week she could meet Sacha Jones (#3 seed; world #183 and CH #150) as early as R2. One very encouraging sign is that Sanders beat Jones in Ipswich before losing to Jelena a few rounds later. On the other hand, Jones might be extra motivated to not lose in the early rounds again.
We'll find out how Jelena does soon enough. Good luck, Jelena!
And I didn't knew that she has 100K title in doubles
Yes, that one is from one of her three million previous comebacks Jokes aside, she is an excellent doubles player (OK, maybe not excellent, but certainly very good) and I'm sure we'll see her in doubles matches very soon.
