AFP/Raleigh, North CarolinaSecond seed Jurgen Melzer and Australian Lleyton Hewitt continued summer hardcourt losing streaks, to exit the Winston-Salem Open Monday. Hewitt, now ranked 165th after standing number one with two Grand Slam titles a decade ago, was defeated by Slovenian Blaz Kavcic 6-4, 7-6 (7/3). The 30-year-old Hewitt has been plagued this season with slow a recovery from foot surgery. He last played a month ago, winning a round in Atlanta before exiting. Hewitt went out in one hour, 40 minutes, losing serve four times. “It could have gone better,” said Hewitt of his loss. “I’m still struggling a little bit with the foot. I knew he was a good competitor coming into the match. “Before the Open I’ll have to hit a lot of balls, get a lot of treatment and see what happens.” Melzer, a French Open semi-finalist and Wimbledon doubles champion last year, went down 7-5, 6-3 to Russian Igor Andreev and has now lost in all three of his starts on the North American hardcourts. “It was a tough match, a tough first set,” said Melzer. “At 5-5 I had lots of break points but couldn’t convert them. At the moment I’m not winning the important points. “If you can’t do that then you can’t win matches. In the second set I let him off from several 0-30 situations. You really do need some luck. Unless you are playing really well you hardly ever get that. “I’ll take a day off on Tuesday and then fly to New York and get on the practise court. I need to get some training in my legs and feel the ball again. “I’ll hope to get through the early rounds of the Open without damage and get my confidence back. That’s the most important thing right at the moment.” The 18th-ranked Austrian was put out in his openers in Washington at the start of the month and last week in Cincinnati after suffering with injury. The 81st-ranked Andreev started his week on Sunday at the last tune-up before the US Open, defeating Australian teenager Bernard Tomic.
