Roddick, Davydenko move on at the Open

Flushing Meadows, NY (Sports Network) - Birthday boy Andy Roddick and fourth- seeded Russian Nikolay Davydenko were among Thursday's second-round winners at the 2007 U.S. Open.
Celebrating his 25th birthday, the fifth-seeded Roddick got past an injured Jose Acasuso 4-6, 6-1, 6-2 in 90 minutes at Ashe Stadium, as the Argentine quit after three sets due to a left leg injury that required treatment on a few occasions on Day 4. A hobbled Acasuso uncorked 27 unforced errors before his exit.
Roddick, who fired 12 aces in his three sets against Acasuso, was last year's U.S. Open runner-up to Roger Federer and captured his lone major title here in New York four years ago.
The French Open semifinalist Davydenko dispatched oft-injured German Nicolas Kiefer 6-2, 6-2, 6-2 in 1 hour, 45 minutes. The gritty Russian broke Kiefer's serve a whopping six times and will now meet Spaniard Nicolas Almagro here on Saturday.
Ninth-seeded Czech slugger Tomas Berdych breezed into the third round with a 7-5, 6-3, 6-3 victory over Italian Simone Bolelli, while an upset came when Korean Hyung-Taik Lee took out 14th-seeded Argentine Guillermo Canas 7-5, 7-5, 6-3 on the grounds at the USTA Billie Jean King National Tennis Center...Full Story
