- US men produced an historic low in their home Grand Slam Wednesday.
The first-round exits of Steve Johnson and Ryan Harrison on Wednesday meant just three American men reached the second round, the fewest in US Open history.
John Isner, the 13th-seeded US number one, Sam Querrey and wildcard Tim Smyczek all booked their second-round berths on Tuesday.
As the men's first round wrapped up, sixth-seeded Czech Tomas Berdych brought Lleyton Hewitt's 62nd Grand Slam appearance to a quick end, downing the former world number one, and 2001 champion, 6-3, 6-4, 6-3.
Seventh-seeded Bulgarian Grigor Dimitrov finally ended his US Open jinx. After coming up empty in three straight appearances, he defeated US wildcard Ryan Harrison 6-2, 7-6 (7/4), 6-2.
