Nadal continues downward spiral

With only four weeks until the start of the French Open, we're beginning to see who is going to be match-ready for the much-anticipated clay-court crucible at Roland Garros. With three more tournaments completed this past weekend, here's who's trending up or down.


No. 1 Serena Williams: The 19-time Grand Slam champion didn't play an event last week yet still managed to accomplish a lot. She woke up Monday morning as the No. 1 player in the land for the 114th straight week, passing Chris Evert for the third-longest streak in history. Williams has 42 more weeks to go to catch Martina Navratilova (156) for second, and in a little more than a year, Williams could pass Steffi Graf (186) for the record. Given Williams' poor effort at the Euro Slams a year ago -- she lost in the second round at the French Open and the third round at Wimbledon -- with good showings this year she could potentially pick up a lot of rankings points and further distance herself from the field.


No. 3 Maria Sharapova: Coming off an encouraging season in 2014, Sharapova has slowly fallen off the map. After taking a monthlong break upon losing her opening match in Miami, Sharapova promptly fell in her first match in Stuttgart, where she was a three-time defending champion. Credit her opponent (and eventual champ) Angelique Kerber, who played brilliantly, but Sharapova didn't help her cause, littering the court with 40 unforced errors.


No. 4 Rafael Nadal: Roger Federer recently said that Rafael Nadal is still the favorite to win the French Open, but all indications suggest Nadal's journey could be fraught with roadblocks. First and foremost, he has openly admitted his confidence has been waning. Still, that hardly explains another loss against Fabio Fognini -- a talented yet enigmatic player -- in the round of 16 (Nadal's second match) at the Barcelona Open. This came a week after the 14-time Slam champ suffered a lopsided loss versus Novak Djokovic in the Monte Carlo semis.


No. 5 Kei Nishikori: With a 26-5 record in 2015 and two titles so far, Nishikori suddenly appears to be a favorite at the French Open. The Japanese star is coming off a title in Barcelona, but it's not the title alone that encapsulates his stellar week. It's how he did it. Despite the high-bouncing and slow red clay, the fifth-ranked Nishikori stood firm on the baseline, attacking early, much as he did during his run to the US Open final last summer. Nishikori, who successfully defended his championship at the tournament Nadal once owned, said he now has heaps of confidence as the heart of the clay season approaches.


No. 5 Caroline Wozniacki: Despite the onslaught of media attention off the court, Wozniacki hasn't lost her focus on the tennis court. She is coming off a run to the Stuttgart final, where she beat Simona Halep in a thrilling 2-hour, 58-minute semifinal before falling to Kerber in the finale. It was Wozniacki's first premier-level final in three years.


No. 12 Angelique Kerber: Quick, raise your racket if you know who owns the longest winning streak on the WTA Tour? We'll forgive you if the name Angelique Kerber didn't pop up right away. After failing to win a single title in 2014, Kerber improved to 11-0 on clay courts this season with a title at Stuttgart. Along the way, Kerber beat world No. 2 Sharapova (she has since fallen to No. 3) and Ekaterina Makarova, an Aussie Open semifinalist this year.


No. 31 Guillermo Garcia-Lopez: He's not a guy who garners headlines, but Garcia-Lopez is a player few would like to meet on clay. After beating Marcos Baghdatis, Lukas Rosol and Gael Monfils en route to the BRD Nastase Tiriac Trophy final, Garcia-Lopez edged Jiri Vesely 7-6 (5), 7-6 (11) on Sunday to lock up his fifth career title and second this season. Last season, Garcia-Lopez reached the fourth round at the French Open, and at 31 years old, he could go further in 2015. Jumping 14 spots, he is now ranked No. 31 in the world, good enough to get him a seeding at Roland Garros.


No. 42 Pablo Andujar: Meet your biggest mover of the week. Andujar jumped 24 spots in the rankings after reaching the Barcelona Open final, where he fell to Nishikori 6-4, 6-4 despite entertaining the crowd with a dazzling display of shot-making. Even Nishikori admitted he was lucky to escape the second set against the Spaniard. Andujar is a three-time winner on the ATP Tour, with all his titles coming on clay.
