World No. 6 Eugenie Bouchard had never lost in the opening round of a Grand Slam — until Tuesday at the French Open.  Bouchard, who reached the semifinals at Roland Garros last season, lost to France’s Kristina Mladenovic in the first round at Roland Garros, 6-4, 6-4, the latest chapter in a disappointing season.  The 21-year-old became the highest seeded player to fall in the tournament, thus far.  “About today, I mean, honestly, I don’t know what to say,” Bouchard said (via WTA). “I felt I was in the match. But tennis-wise, I still knew I was far off from how well I can play. But, you know, I was in there. It’s been kind of the same as how I have been feeling recently on the court. Just not like myself.”  Bouchard has lost seven of her past eight matches and hasn’t reached the quarterfinals of a tournament since the Australian Open, where she lost to Maria Sharapova in straight sets.  Mladenovic, ranked 44th in the world, stormed to a 5-0 lead in the second set before Bouchard rallied to 5-4, but was able to serve out the match to earn her first win against a top 10 player in a Grand Slam.  Bouchard now turns her attention to the grass-court season, where her success last year included a runner-up finish at Wimbledon. It was the first time a Canadian player – male or female – reached a Grand Slam singles’ final.  “Hopefully the grass will be good for me,” she said (via WTA). “Plans are to go and play a couple of warmup tournaments.”  Sock upsets No. 10 Dimitrov  American Jack Sock started off his French Open campaign with a 7-6 (9-7), 6-2, 6-3 win over No. 10 seed Grigor Dimitrov of Bulgaria – the biggest men’s upset so far this year.  It was only the 22-year-old Sock’s 14th victory on clay. Sock is the first American to beat a top 10 seed at Roland Garros since Jan-Michael Gambill upset No. 8 Nicolas Kiefer in the 2000 first round, according to the ATP.  “Today was a great match for me,” Sock said (via ATP). “Things that I look to do well when I’m playing my matches I thought I did very well today: serving, forehand. Obviously most people know the things I look for the most. I thought I executed them very well. For the most part I took care of my serve fairly well and was able to get into a lot his service games and make him play some balls.”  Dimitrov has now lost in the first round at the French Open in two straight years, while Sock picked up his eighth career win over a top-20 player and first in a Grand Slam. Sock earned his first career ATP title at the U.S. Men’s Clay Court Championship in Houston last month.  “I feel like if I play some of my best tennis I have a chance against anybody,” Sock said (via ATP). “[Dimitrov and I] played in Stockholm last year and I had a break point chance; we played two great sets, both of us, split. I had a chance in the third to get a break up and serve for it. But it was a great match overall. He was able to take it at the end.  “Obviously that gave me some confidence going into today knowing I already played a close match with him. And then to play on clay, which I think suits me a little more.”  Kelyn Soong is a news aide and blogger and covers high school tennis for The Washington Post sports section.
