Four American men — Denis Kudla, Bobby Reynolds, Wayne Odesnik and Alex Kuznetsov — qualify for Wimbledon.
Eight other U.S. men are already in the main draw, including 21st-ranked John Isner, who will be the highest-seeded American male as his seed was bumped up to No. 18, allowing him to pass Sam Querrey. The 19th-ranked Querrey is seeded No. 21.
Wimbledon uses its own seeding formula that takes into account a player's results on grass over the past two seasons as well as their current ranking. Isner won his second straight Newport title on grass last July; Querrey was the 2010 Queen's Club champion.
