Jack Sock on Sunday announced on social media that the US Open will be his final tournament.

“To the 8 year old boy who immediately fell in low with the sport of tennis. I hope I made you proud,” Sock posted on Instagram. “It’s been 14 years of memories I will never forget. From winning four Grand Slams, Olympic Gold and Bronze, Top 10 rankings in singles and doubles and competing on the Davis Cup and Laver Cup teams, it’s been beyond what I could’ve ever dreamed. Without the help of so many people, none of that could’ve happened.”

The American made his tour-level debut at the US Open in 2010 and went on to win four singles titles, including the ATP Masters 1000 crown in Paris in 2017. The 30-year-old also lifted 17 tour-level doubles trophies, winning the Nitto ATP Finals crown in 2018 with Mike Bryan.

Sock, who reached a career-high No. 8 in the Pepperstone ATP Rankings, will compete for the final time at the US Open, where he will play doubles alongside John Isner, who is also retiring following the hard-court major.
