We've witnessed many beautiful moments of sportsmanship so far, here's a look at some of them. Juan Martin del Potro bows in respect to his Japanese opponent Yoshihito Nishioka after the Argentine won their five-set duel in the second round on Thursday. Benoit Paire gave Pierre-Hugues Herbert multiple hearty hugs after the former defeated the latter 11-9 in the fifth set in the second round. Dominika Cibulkova hugs Lucie Safarova after they lost in doubles, in what was Safarova’s very last match of her professional career. Cibulkova stepped in last minute to play doubles with Safarova and honour the Czech in her swansong after Bethanie Mattek-Sands had to withdraw with an injury.
