The powerful 20-year-old arrives at Wimbledon after a mixed 2005 season.
Zvonareva has developed a worrying trend of losing to players ranked outside the top 50, who she would normally be expected to beat.
The Russian failed to reach at least the third round of a Grand Slam for the first time in two years when she was knocked out of the Australian Open by world number 65 Vera Douchevina in her second match in Melbourne.
Things improved for Zvonareva in Memphis where she defended her title - the third of her career.
But losses to lower-ranked players followed at Miami, Amelia Island, Charleston, Warsaw and Berlin.
The only consolation in Berlin came where she teamed up with compatriot Elena Likhovtseva to claim the doubles title.
Zvonareva's season steadily improved in Rome, where she lost in the semi-finals to eventual winner Amelie Mauresmo.
And at Roland Garros she was narrowly beaten by eventual runner-up Mary Pierce in an intense third-round contest.
The Russian 20-year-old will aim to keep the momentum going at Wimbledon as she bids to reach the fourth round for the third year running.
