Jack Sock wins the USTA Winnetka Challenger and cracks the Top 100 for the first time at No. 84. The 20-year-old is now the fourth-highest-ranked U.S. male and has secured himself a main draw spot in the U.S. Open.
“I have a good amount of confidence. Hopefully I can ride the wave and keep it going,” Sock told the Providence Journal after advancing to the second round of Newport. “[Getting directly into the U.S. Open is big for me and big for my self-confidence.”
