Former champion Justine Henin was an easy second-round winner Wednesday at the $220,000 Unicef Open, a final grass-court Wimbledon tuneup. The top-seeded former world No. 1 Henin blew past Italian Roberta Vinci 6-3, 6-3 at Autotron Rosmalen. The Belgian great advanced in 1 hour, 16 minutes with the help of five service breaks in nine chances. The Australian Open runner-up Henin is playing her first tennis since losing to Aussie Samantha Stosur in the fourth round at the French Open two weeks ago. This also marks her first grass-court event since losing in the Wimbledon semifinals back in 2007. The 28-year-old Henin, who retired from tennis in the spring of 2008 and returned to the WTA Tour this past January, captured this Dutch event in 2001 and was the runner-up here in 2003. http://www.tsn.ca/tennis/story/?id=324801
