Rafael Nadal continues winning start

World number two Rafael Nadal has continued his winning start to 2012 with a victory over Denis Gremelmayr at the Qatar Open.

Nadal made light work of his German opponent, taking just over one hour to record a 6-2 6-2 success to advance into round three.

The Spaniard showed little sign of a shoulder injury that appeared to be troubling him in his round one tie against Philipp Kohlschreiber yesterday afternoon.

His round three opponent has yet to be decided.
