Rosol rose to prominence in 2012 at the Wimbledon Championships, after having participated in the Wimbledon qualifying draw multiple times, not reaching the main draw until then. In the first round, he defeated Ivan Dodig, then he was drawn against the two-time champion and world No. 2, Rafael Nadal. After losing the first set in a very close tiebreak, Rosol regrouped and broke in the first game of the second. A dominant serving performance allowed him to take the second set 6–4. Rosol's service game held up in the third set, where he capitalized on a sloppy game by Nadal and took the set 6–4. Down two sets to one, Nadal raised his level in the fourth, taking the set 6–2 and sending the match into a deciding fifth set. At this point the match was delayed by 35 minutes in order to close the Centre Court roof. Rosol returned from the break revitalized, taking the fifth set 6–4 by striking 20 winners to two unforced errors. His groundstroke speed averaged 85 mph and peaked at 114 mph. In the final game of the match, Rosol delivered three aces and a forehand winner to close out one of the greatest upsets in Grand Slam history by a score of 6–7(9–11), 6–4, 6–4, 2–6, 6–4. He went on to lose his third-round match against Philipp Kohlschreiber in straight sets.
