ATP: Davydenko, Roddick bow out in Austria

Prtschach, Austria (Sports Network) - Top-seeded and two-time defending champion Nikolay Davydenko and former world No. 1 Andy Roddick were a pair of upset victims in Thursday's quarterfinal action at the Hypo Group Tennis International, a final clay-court French Open tune-up.
Capable Argentine Juan Monaco knocked out Davydenko in 6-2, 6-7 (5-7), 6-4 fashion at Werzer Arena. The Russian Davydenko beat 2000 champion Andrei Pavel of Romania in last year's finale here and was the 2003 Prtschach runner-up to Roddick.
The U.S. Open runner-up and second-seeded Roddick was upended by French wild card Gael Monfils 7-5, 6-3. Monfils, who will appear in his first ATP-level semifinal in 12 months, is rewarded with a semifinal match against another former top-ranked star, two-time major champion Lleyton Hewitt, who pasted Argentine Diego Hartfield 6-2, 6-2 on Day 5. The fourth-seeded Hewitt was a semifinalist at last week's Hamburg Masters.
The world No. 3 Roddick has failed to title in all six of his events so far this season.
Friday's other semi will pit Monaco against Peruvian Luis Horna, who advanced with a 7-6 (7-4), 6-7 (2-7), 6-1 decision against Spaniard Albert Montanes.
