Raonic represented Canada at the London 2012 Olympics and competed in the singles competition as an unseeded player. He won his first-round match over Japan's Tatsuma Ito in straight sets. In the second round, Raonic lost to French player Tsonga 3–6, 6–3, 23–25, breaking three Olympic tennis records. The match holds the records for the most games played in a best-of-three sets match (66 games) and the most games played in a single set (48 games) in Olympic history. At the time, it was the longest Olympic match by time played (3 hours 57 minutes), but this record was broken three days later in the semifinal match between Federer and del Potro (4 hours 26 minutes).
