Young American Jack Sock upsets second-seeded Tommy Haas in Auckland, avenging a loss to the 12th-ranked German at Roland Garros last year and scoring his first win over a Top-15 ranked player in the process.
Currently ranked No. 100, Sock reached the third round of 2012 U.S. Open, but sputtered in 2013, posting a 10-13 record. John Isner is only American man currently in the Top 40 at No. 14. Sock, who is ranked behind Sam Querrey, Tim Smyczek, Michael Russell, Bradley Klahn, Donald Young, and Ryan Harrison, said the younger Americans push each other to improve.
"It’s a hot topic, a lot of people like to talk about it but it is what it is,” the 21-year-old told The New Zealand Herald. “I think the younger generation around my age, there are a lot of us making strides and getting better but it's tough. We are pushing each other to hopefully bring American tennis back to what it was and what people remember. Everyone is looking for that next one and I'm hoping it will be me."
