Switzerland's Roger Federer has beaten Holland's John Van Lottum in straight sets to make it through to the second round of the ATP tournament in Rotterdam.
The Swiss was rarely troubled during his 6-3, 6-4 victory, making it four wins out of four against the Dutchman.
It was Federer's first outing since pulling off an impressive double in Switzerland's Davis Cup defeat against Russia almost a fortnight ago, when he beat world number seven Marat Safin and world number four Yevgeny Kafelnikov both in straight sets.
Federer withdrew from last week's Marseille Open with a hip injury. In the second round he joins compatriot Ivo Heuberger, who pulled off the surprise of the tournament so far in beating Wimbledon champion Goran Ivanisevic in the first round.
Gagliardi knocked out
Meanwhile Swiss women's number three, Emmanuelle Gagliardi, has been knocked out in the second round of the WTA tournament in Dubai.
Gagliardi was beaten by the tournament's number three seed, France's Amélie Mauresmo, in just two sets, 6-3, 6-2. The defeat came after the 25-year-old Genevan won Tuesday's first round match 6-4, 6-3 over Australia's Nicole Pratt in straight sets.
The win over Pratt was Gagliardi's first since her surprise victory over Russia's Elena Likhovtseva in the opening round of January's Australian Open.
