Didn't win a major in 2015 but had a big year otherwise, getting married in April and guiding Britain to its first Davis Cup title in 79 years, going 11-0 (8 singles, 3 doubles) to become only the second player since the existing World Group structure was introduced to win 11 live matches in a Davis Cup season. ...

Reached 11 finals in 2015 and won six. ...

Topspin: 2015 was the first season since 2004 that he didn't win a major title, although it was the first since `11 that he participated in all four majors. ... The True Blue courts at Melbourne Park are far from his favorite surface, and he's won fewer majors here than anywhere else, not surprising for the best clay courter of all time . ..He won the title here in 2009 and lost to Djokovic in the 2012 decider, the longest - at 5 hours, 53 minutes - and latest-finishing final in Grand Slam history. ...
