27-year old Czech cutie and regular first round Grand Slam loser, Klara Zakopalova, took the play to Serena and seemed to have the number two seed on the ropes on Day Three. Despite her inability to finish off the American star, Klara’s fan base grew as the strong possibility of an upset rose.

Serena inexplicably lost both her concentration and serve as the second set wound down. The perennial Czech also-ran fought off six match points in set two and then ran off four service breaks in the tiebreaker to notch a stunning second set win.

Williams dug a deeper hole when Klara broke early in the third set. In the unfamiliar role of leading a top seed in the first round, Klara pressed ahead. Williams, who only landed 55% of her first serves, broke back at 1-2 and seemed to get her wind once the match evened.

Klara had built her momentum by winning 6 of 7 net advances and converting 5 of 11 break point opportunities. Her serve was steady but not overpowering as she recorded three aces.

Clay is Klara’s surface of choice. The competitive Czech advanced to the second round in Paris last year. The svelte blonde made some new friends on Day Three, but her career needs a boost. Currently ranked number 100 in the WTA, she is 7-12 in 2009 matches.

On Day Three, she had Serena Williams on the ropes and made the struggling American, who has lost four straight matches, look out of sorts. Williams appears troubled by a nagging left knee injury and appeared top be laboring on the red clay.

In other women’s matches, fourth seeded Elena Dementieva and fifth seeded Jelena Jankovic advanced without incident. The two seem headed for a pivotal quarter-final match-up.

Dementieva’s 6-4, 6-3 win over Chanelle Scheepers earns her a second round pairing with Australian comeback specialist Jelena Dokic, who clawed out a three set win over Croatia’s Karolina Sprem. It was no walk in the park for Elena, but her consistent groundstrokes were too much for the feisty Scheepers.

Jankovic breezed past Patra Cetkovska en route to a 6-2, 6-3 win. The former number one next plays Slovakia’s Magdalena Rybarikova.

Men’s Singles
Fourth Seed Novak Djokovic and fifth seed Argentinean Juan Martin Del Porto took different routes but cruised into the second round. Djokovic is still riding the wave of his recent Madrid marathon clay match with top seeded Rafael Nadal. The troubled Serbian star has a solid fan base in Paris and this time, that base is expecting, almost demanding, results.

Djokovic finds controversy. The big Serb’s game can be so impressive that tennis buffs become frustrated with Djokovic’s inconsistencies. On Day Three, Novak advanced by way of Ecuador’s Nicolas Lapenti’s early retirement during set two. Djokivic led 6-3, 3-1 when the match was conceded.

Argentina’s Juan Martin Del Porto was his usual, convincing self in disposing of France’s Michael Llorda, 6-3, 6-3, 6-1. Like American Roddick, Spain’s Fernando Verdasco, France’s Gilles Simon and to a degree even Andy Murray and Novak Djokovic, Del Porto waits on the cusp of greatness as perennial fan favorites and proven stars Roger Federer and Rafael Nadal seem to grab the Grand Slam spotlight.

Fans have been patient with Del Porto whose long frame and powerful serve may not be built for Roland Garros success. Against Llorda, Del Porto recorded 7 aces, landed 69% of his first serves and stroked 34 outright winners. The match was over in 1.5 hours.

Barring upset, Del Porto and Djokovic will clash in the quarters. Del Porto would have to put aside France’s Jo-Wilfried Tsonga in the third round to reach Djokovic.
