INDIAN WELLS, Calif. — Defending champion Rafael Nadal defeated Donald Young in their first meeting, and James Blake evened his record against familiar foe Carlos Moya in third-round matches today at the Pacific Life Open.

Nadal beat his 18-year-old American opponent 6-1, 6-3. Blake took a methodical 6-3, 6-4 victory over Moya.

The 21-year-old Nadal, ranked No. 2 behind Roger Federer, benefited from Young's inconsistency.

Although he was able to match Nadal stroke-for-stroke in some rallies and also hit several hard winners that brought roars from the crowd, Young's inexperience was evident at other times.

After hitting a routine forehand out to end a long rally in the second set, Young slammed his racket to the ground in frustration. Soon after, he banged an overhead volley into the net, shaking his head at missing the easy shot.

Young won just seven of 17 points when he went to the net and Nadal was 6-of-7. Young made 38 unforced errors, 13 more than his Spanish opponent.

Nadal dictated the pace for most of the match, keeping Young on the run with well-placed groundstrokes.

Young had scored the biggest victory of his career two days earlier at Indian Wells, beating No. 32 Feliciano Lopez in three sets.

The 28-year-old Blake, at No. 9 the highest-ranking U.S. player remaining in the tournament since No. 6 Andy Roddick was eliminated a day earlier, won for the sixth time in 12 career meetings against Moya, the former No. 1 now ranked 19th.

Moya, a 31-year-old from Spain, had been the oldest player left in the men's side of the tournament.

Jelena Jankovic, the third seed in the women's event, romped to a 6-1, 6-1 victory over Ai Sugiyama.
