Top seed Roger Federer struggled to defeat Finn Jarkko Nieminen 7-5, 7-6 to reach the semi-finals of the World Indoor Tournament.
The Swiss, who is this week making his first appearance in the Dutch port city since he won the title in 2005, lacked rhythm against the unseeded Nieminen yesterday.
Former world number one Federer came back from 40-0 down in the 11th game to break serve on the indoor carpet and then had to rely on the tie-break to clinch victory in the second set.
