Because of his style of play, that consists of a big, consistent serve, he often ends up winning a great majority of his service games. But at the same time, due to poor movement around the court, he often finds it difficult to break the opponent's serve, especially those players that move him around the court. This often finds him involved in long matches where each player continues holding serve until the set reaches the tiebreak. At Grand Slams where there are no fifth-set tiebreaks (since 2019 only Roland Garros, but before also Wimbledon and the Australian Open), his matches can extend very long, as evidenced by the fact that he was a player in the two longest-ever Grand Slam matches, both at Wimbledon in 2010 and 2018, respectively.
