ROME, May 7 (Xinhua) -- China's Bu Yunchaokete bowed out of the first round of the ATP Italian Open after losing in straight sets to local player Luciano Darderi on Wednesday.

In their first career meeting, Bu failed to convert his two break points in the opening set despite Darderi's first-serve percentage dropping below 50 percent. Both players held serve through the first 12 games, sending the set into a tiebreak, where Bu earned a mini-break and moved ahead 4-2. However, a double fault shifted the momentum, allowing Darderi to reel off five consecutive points to clinch the set 7-6 (4).

During the second set, Bu suffered a break in the opening game. After trailing 2-1, Bu called a medical timeout to treat his shoulder issue. Both players then held serve through the next five games, before Bu was broken again in the ninth game as Darderi closed out the match 6-3.

The Italian will face world No. 5 Jack Draper in the second round.■
