Third seed Stanislas Wawrinka is through to the quarter-finals of the US Open after defeating Ukraine's Illya Marchenko in relatively comfortable fashion, winning 6-4 6-1 6-7 6-3.
However, if you were to take a look at Wawrinka's collection of rackets, you would be forgiven for thinking the Swiss had struggled somewhat.
The former Australian and French Open champion destroyed his racket as he grew increasingly frustrated with himself during his fourth round encounter with Marchenko.

Becoming angered by the resistance of Marchenko in the third set, and his inability to put away the unseeded Ukrainian, Wawrinka took his anger out on his racket, launching it across the court after initially hitting it into the ground and snapping it over his knee.
These actions were shocking, as throughout the first two sets, and the eventual fourth and final set, Wawrinka played some mouthwatering tennis to dispatch Marchenko, conceding just eight games in the three sets.
The third seed is now in a good position to reach the semi-finals of the US Open in an attempt to add to his two previous Grand Slam victories in Melbourne and Paris.
Failure to do so would result in Wawrinka failing to win a major in the calendar year for the first time since 2013.

Progressing to the semi-finals will be no straightforward task, however, as Wawrinka faces Olympic silver medallist, and former US Open winner, Juan Martin del Potro, who recently made his return to the tour after an extended injury break.
Victory for Wawrinka would see him face either Japanese sixth seed Kei Nishikori, or Wimbledon champion Andy Murray in the semi-finals.
