The next decade of Woods' career was marked by comebacks from personal problems and injuries. He took a self-imposed hiatus from professional golf from December 2009 to early April 2010 in an attempt to resolve marital issues with his wife Elin at the time. Woods admitted to multiple infidelities, and the couple eventually divorced. He fell to number 58 in the world rankings in November 2011 before ascending again to the number-one ranking between March 2013 and May 2014. However, injuries led him to undergo four back surgeries between 2014 and 2017. Woods competed in only one tournament between August 2015 and January 2018, and he dropped off the list of the world's top 1,000 golfers. On his return to regular competition, Woods made steady progress to the top of the game, winning his first tournament in five years at the Tour Championship in September 2018 and his first major in 11 years at the 2019 Masters.
