Switzerland’s Roger Federer won his second title at the Rotterdam Open seven years after his first as he defeated Argentine Juan Martin del Potro 6-1 6-4 on Sunday.

Federer now owns 71 career trophies after lifting his first of this season. He finished 2011 with three straight titles indoors at Basel, Paris Bercy and the London year-end ATP championship.

The victory took Federer’s record against Del Potro to 9-2, with the Swiss winning three of four in the series after losing the 2009 US Open final to the South American.

Federer has now assured himself of a 12th consecutive year in which he has won at last one ATP title.
