Valencia - Jo-Wilfried Tsonga was given a scare by Spanish teenager Javier Marti before rallying to win their first-round match at the Valencia Open 4-6, 7-5, 6-2.
The second-seeded Frenchman had won 11 of his last 13 matches coming in, including titles at Metz and Vienna. But Tsonga trailed early due to unforced errors and the smooth backhand of the 19-year-old wildcard, who was playing his first match against a top-10 player.
While Tsonga complained about the streaks of sunlight on the City of Arts and Sciences indoor court, he settled toward the close of the second set after Marti double-faulted to be broken and served out the set on his way to victory.
Top-seeded David Ferrer's title defense begins later on Tuesday against fellow Spaniard Fernando Verdasco.
