MADRID: Dani Pedrosa came through surgery on his troublesome collarbone successfully and the Repsol Honda rider is aiming to return for the Portuguese Grand Prix on May 1, his team said Wednesday. The Spaniard, second in the MotoGP standings behind champion and compatriot Jorge Lorenzo after two races, used a break in the MotoGP calendar due to the postponement of the Japanese Grand Prix to have the operation at a clinic in Barcelona. He had surgery on a collarbone fracture last October.
