There is an old proverb that says: when the river sounds it's because it carries water. And of late, Jack Sock has made his own share of noise with a strong run on the tour. Currently, the 24-year old is the top-ranked American in ATP singles (world no. 18) and has an impressive record of 11-2 in 2017.

He opened the year winning the title in the Auckland ATP 250 event, beating Joao Sousa in the final in three sets. He suffered his first defeat of the season against Jo-Wilfried Tsonga (ranked no. 12 at that time) in the third round of the Australian Open in four tights sets.

However, at the end of January, Sock helped the USA defeat Switzerland 5-0 by winning his two matches (one in singles and the other in doubles), as they advanced to the quarterfinals of Davis Cup.

Sock kept his winning streak alive in February at the Delray Beach Open, reaching the final and he secured the title after his opponent Milos Raonic, withdrew due to a leg injury.

It’s worth noting that Sock has also been successful in doubles, as well.  He is currently ranked world no. 17.  At the 2016 Rio Olympics, he won two medals, Gold in mixed doubles with Bethanie Mattek-Sands and Bronze in Men's doubles with Steve Johnson. That same year he teamed up with John Isner to win the ATP World Tour Masters 1000 in Shanghai.

His success in doubles goes back to 2014 when he paired with Vasek Pospisil at the last minute to win his first Grand Slam title at Wimbledon, beating the Bryan brothers in the final. And in 2015, with Pospisil again, he won at Indian Wells, Beijing and Stockholm.

But this year he appears to have decided to reduce his doubles workload and focus more on singles, which appears to have paid off. This, after a heavy load of singles and doubles matches in the latter part of 2016.

The development of Sock seems to be of integral form. He has improved his concentration, his discipline and he looks to be more comfortable on the court.

While his best results have been on hard surfaces, Sock likes to play on clay and has planned to play as many clay tournaments as he can, including Monte Carlo, Madrid, and the French Open.

Sock has shown another important variable as he has displayed a good vibe of late. Will 2017 be his breakthrough year? It remains to be seen but if the start to his year is any indication, he will continue to make plenty of sound.
