Americans William Blumberg, Christian Harrison, Tommy Paul, and Alex Rybakov have been chosen as wild card participants for 2017.

Harrison possesses the highest ranking of the four wild cards at No. 279. The 23-year old is the brother of ATP Tour pro Ryan Harrison and currently trains at the prestigious IMG Academy in Bradenton. He has climbed over 1,000 ranking points in the last year to reach his current standing which is also his career high. Harrison has won two International Tennis Federation (ITF) Futures titles with his most recent victory in August of 2016 in Champaign, Illinois.

Paul (No. 290) leads the race for the US Open Wildcard Challenge after reaching the semifinals in the Winnetka Challenger last week. A 2015 French Open juniors champion, the 20-year old from Boca-Raton, Florida has won six futures titles in the past two years.

Blumberg recently wrapped up his freshman year at the University of North Carolina where he was the NCAA Singles Runner-Up. The 19-year old was named the NCAA Tournament Most Outstanding Player and a singles and doubles All-American. He was also the 2017 ITA National Rookie of the Year and ACC Freshman of the Year after he finished with a 31-3 singles record, going undefeated against ACC opponents. Born and raised in Connecticut, Blumberg has since made a qualifier of the only futures event he’s played in and won a qualifying match at the ATP Newport event.

Rybakov (No. 629) just completed his sophomore year at Texas Christian University (TCU), finishing with a 23-2 singles record. He was a 2017 ITA Singles All-American and a 2016 ITA National Men’s Rookie of the Year and Texas Region Rookie of the Year. Since the end of the NCAA season, the native of Plainview, New York has won the futures event in Buffalo and qualified at the Winnipeg Challenger last week.
