Former No. 1 Lleyton Hewitt knocked out Juan Monaco of Argentina 6-3, 6-4 in the opening round of the Valencia Open on Monday, ending a 10-match losing run against top-10 opponents.
The Australian wild-card entry broke the 10th-ranked Monaco twice in the opening set and three times in the second at the indoor hard-court tournament. The loss makes it difficult for the Argentine to qualify for the season-ending ATP World Tour Finals in London.

Fernando Verdasco beat Tommy Robredo 6-3, 6-4 in an all-Spanish match and will play Marin Cilic of Croatia. David Goffin of Belgium beat Pablo Andujar of Spain 6-2, 6-2.
