Rafael Nadal [Images] made a smooth start to his bid for a fourth consecutive Barcelona Open title as he powered to a 6-4, 6-2 win over Italy's [Images] Potito Starace in the second round on Wednesday.

The top seed and three-times French Open champion continued his winning run following his triumph in Monte Carlo last week and eased to victory in 78 minutes.

Nadal will now play Spanish compatriot Feliciano Lopez for a place in the quarter-finals.

Swiss Stanislas Wawrinka eased past Yuri Schukin, a lucky loser from Kazakhstan, 6-3, 6-4 to set up a third-round clash with third seed David Nalbandian.
