Third seed Casper Ruud defeated Tennys Sandgren 7-5, 6-2 in the second round of the Geneva Open on Wednesday. The Norwegian - a claycourt specialist - has produced some fine tennis in recent weeks, as he builds towards the French Open. By contrast, the American prefers faster surfaces- much better suited to his aggressive, hard-hitting game. That aggression was there on Wednesday - but it wasn't quite enough.
