Ferrer Wins in Straight Sets June 4, 2012, 8:38 am PARIS - David Ferrer of Spain displayed one glaring weakness in his 6-3, 6-2, 6-0 victory over countryman Marcel Granollers on Monday at the French Open. As the score indicates, Ferrer's fault didn't matter that much. Still, there it was. Despite his evident strength, the 6th-seeded Spaniard repeatedly mis-hit short balls, the kind a player can use to attack the net and take away the point. Leading 5-3 in the first set, Ferrer found Granollers coming up short, his forehand suddenly less potent. Yet Ferrer missed three of the four chances he had, repeatedly slamming the ball into the net or over the baseline. The shots mattered. Ferrer was facing two break points and could have found himself staring at a resurgent foe. Ferrer dealt with his weakness by staying back and slamming balls from corner to corner. Under this pounding, Granollers made two critical unforced errors, a backhand slice that hit the net and an easy backhand that Granollers sent to the bottom of the net. Stiffening his defenses and avoiding rushes to the net, Ferrer won the first set in 44 minutes. Granollers, seeded 20th, had no weapons to exploit Ferrer's modest weakness and rapidly lost ground. Soon it was a rout, Ferrer picking the pace and slamming a match-long total of 41 winners to Granollers's 17. The two men made a modest clutch of unforced errors: Ferrer 22, Granollers 23. The victory moved Ferrer into the quarterfinals, where he will face the winner of a match later in the day between Andy Murray of Britain and Richard Gasquet of France.
