Rafael Nadal's late-season resurgence continued on Monday as he defeated Stan Wawrinka 6-3 6-2 at the ATP World Tour Finals in London.
The Spaniard has had a poor year by his standards, with quarter-final defeats at the French and Australian Opens being followed by early exits at Wimbledon and the US Open, but he has achieved a number of encouraging results since September.
Nadal's growing confidence was on full display against Wawrinka on Monday night.
Wawrinka broke in the first game of the match for a 1-0 lead, though his advantage was short-lived as Nadal broke back at his first opportunity.
From there it stayed on serve until Nadal pounced in the eighth game, succeeding on his third break point of the game as Wawrinka overcooked his forehand.
The Spaniard held serve to go one set up and immediately started applying pressure at the start of the second.
Wawrinka saved an incredible seven break points during a marathon first game, but it only managed to delay the inevitable.
Growing in confidence and increasingly in control of the exchanges, Nadal would break in games three and five to ultimately coast to a comfortable victory.
