Weary Venus Williams loses at Key Biscayne

KEY BISCAYNE, Fla. (AP) -- Venus Williams looked weary Wednesday after winning three consecutive three-set matches, and she lost to Agnieszka Radwanska in the quarterfinals of the Sony Ericsson Open, 6-4, 6-1.

Williams' serve lacked its usual velocity, and by the final game she wasn't even chasing after shots in the corner.

The tournament was Williams' first since the U.S. Open last August, where she withdrew after being diagnosed with a fatigue-causing autoimmune disease.

Eager to keep points short in the 85-degree sunshine, Williams charged the net often but frequently had to lunge for shots. She committed 38 unforced errors and won only five of 26 points on her second serve.

Williams is ranked No. 134 and projected to climb next week back into the top 90.
