London: Rafael Nadal put fellow Spaniard David Ferrer firmly in his place as he opened his ATP World Tour Finals challenge with a crushing 6-3, 6-2 victory at the o2 Arena on Tuesday.
Ferrer had beaten the world number one three days previously in the semifinals of the Paris Masters but normal service was resumed as Nadal profited from an error-strewn display by his weary-looking opponent.
Nadal joins Stanislas Wawrinka on top of Group A with one win and he now needs one more victory at the season-ending tournament to finish 2013 on top of the ATP rankings.
Ferrer, ranked third in the world, briefly rallied after slipping 5-0 behind in the second set, snatching a couple more games, but he succumbed meekly when he dragged a forehand into the net.
Later on Tuesday defending Novak Djokovic, who still has a slim chance of overtaking Nadal in the rankings, begins his Group B matches with a repeat of last year`s final against six-time winner Roger Federer.
