By the end of 2016, American men on the ATP tour had won a grand total of two singles titles between them. Questions surrounding the state of American tennis would not stop. Now, just one year later, three Americans have won two or more tournaments over the course of the season.
It was quite the turnaround with nine American men finishing in the Top 100. Two young players, Taylor Fritz and Ernesto Escobedo, spent a portion of the year close behind, finishing right outside of the Top 100.
It was a season full of career milestones and dubious streaks coming to an end.
Jack Sock became the first American male to win an ATP Masters 1000 title since Andy Roddick in 2010 when he took home the Paris in the last week of the regular season.
