He won his first-ever ATP singles match in the first round of the 2011 U.S. Open, but truly announced his arrival by winning the mixed doubles title at that same tournament with partner Melanie Oudin. In 2014, he took home a trophy even more surprising. Having never played together prior to the tournament, Sock and Vasek Pospisil joined forces to win the doubles title at Wimbledon over the legendary pairing of Mike and Bob Bryan. Sock and Pospisil achieved great success thereafter, including a 2015 championship in Indian Wells. His singles game improved that year, as well, as he won his first ATP title at the U.S. Men’s Clay Court Championship and broke into the Top 25 in the world rankings. At the 2016 Summer Olympics in Rio de Janeiro, Sock won a gold medal with Bethanie Mattek-Sands in mixed doubles and a bronze with Steve Johnson in doubles.
