Former world No. 8 Jack Sock has been granted a singles and doubles wildcard into Houston. Sock, 29, is now set to make his seventh singles appearance on the clay courts of Houston. Also, Sock will be competing in the Houston doubles event as he and Nick Kyrgios were granted a wildcard into the tournament.
Sock, now ranked at No. 144 in the world, has had success in Houston throughout his career. Sock's first big Houston campaign came in 2015, when he won the title after beating Sam Querrey in the final. The following year, Sock fell just short of winning back-to-back titles at the tournament as he ended runner-up in the final to Juan Monaco.
Sock didn't make the Houston final in 2017 but still it was another good campaign for him as he reached the semifinal. Sock hasn't played in Houston since losing to Taylor Fritz in the quarterfinal in 2018.
Sock, Kyrgios set to play together for the first time this season
Sock and Kyrgios have had success together in the past as they are certainly capable of making a deep run when playing alongside each other.
Sock and Kyrgios debuted as a pair at the Rome Masters in 2015. In their first tournament together - on a surface which they don't really prefer - they made the semifinal. In 2017, Sock and Kyrgios put up another strong run together as they reached the Madrid Masters semifinal before giving Lukasz Kubot and Marcelo Melo a walkover.
At the time, it was their third tournament together and a second semifinal. In their fourth tournament together, Sock and Kyrgios made it all the way as they defeated Roman Jebavy and Matwe Middelkoop in the 2018 Lyon final.
Three years after winning Lyon, Sock and Kyrgios entered a tournament once again. This time, Sock and Kyrgios didn't enjoy a deep run as they were beaten by Steve Johnson and Jordan Thompson in the Atlanta quarterfinal. It remains to be seen how far can Sock and Kyrgios go together in Houston next week.
