A total of 55 games were played in the 2012 Australian Open men's singles final. Novak Djokovic defeated Rafael Nadal in five sets, 5–7, 6–4, 6–2, 6–7(5–7), 7–5.
Adding the games in each set gives 12, 10, 8, 13 and 12, for a total of 55. The fourth set contained 13 games because it reached 6–6 before Nadal won the tiebreak, recorded in the final score as 7–6.
The match lasted 5 hours and 53 minutes, making it the longest Australian Open match and, at the time, the longest Grand Slam final ever played. Djokovic eventually won the deciding set 7–5 after both players had endured an extraordinary physical contest.
A common mix-up is confusing games with sets, points or total games won by one player. The final had five sets, but the complete scoreline—not simply the number of sets—produced the figure of 55 games.
