Intro:

Igor Sijsling upset Mikhail Youzhny as Marin Cilic and Ernests Gulbis also progressed on day two of the ABN Amro World Tournament in Rotterdam.

Script:

The first round of the ABN Amro World Tournament and Ernests Gulbis needed a tie-breaker in the second to get past Denis Istomin. He took the first set with an ace before wearing down his opponent in the second. 6-4 7-6.

Marin Cilic was the other early winner as he outclassed Lukas Rosol.
The Croatian took both sets 6-2, 6-2 with the last point one of his shots of the day..

And there was shock in one of the other matches as hometown favourite and wild card Igor Sijsling beat Mikhail Youzhny 6-2, 6-2. Sijsling served nine aces to nil against seventh seeded Youzhny who was the 2007 champion and 2010 runner-up.

That's the Russian's fourth loss in five games this year. Sijsling now joins the likes of Tomas Berdych and Jo-Wilfried Tsonga in the next round.
