LAS VEGAS, Feb. 27 (UPI) -- Lleyton Hewitt defeated Vincent Spadea, but top-seeded James Blake lost Tuesday during round-robin action at the $416,000 Tennis Channel Open.
The second-seeded Hewitt won 6-3, 6-3, but Blake was beaten by Evgeny Korolev 6-2, 6-4.
The defending champion Blake beat Hewitt in last year's Las Vegas final.
Former world No. 1 Marat Safin of Russia, seeded third, defeated Austrian Stefan Koubek 7-5, 6-2.
Seventh-seeded Brit Tim Henman made his 2007 season debut by beating Frenchman Nicolas Mahut 6-1, 6-2. Playing his first tennis since October, the 32-year-old Henman had been sidelined with a hamstring injury, which forced him to miss last month's Australian Open.
