Houston 250 Clay

[GameSetAndMath]

Has this tourn been so biased at Americans before?
This year it's lamost exclusively American: e.g. top half R16 only 2 overseas players but QF all Americans! Bottom half also many Americans. And the winner (Johnson) went through all 5 matches all American!
If someone's thinking American Era of tennis is not as good as 20-30y ago, this tourn may (incorrectly) suggest USA players are again all over.

You should notice that this tournament is being held the week before Monte Carlo. Most European players like to play at MC and that being a big event, don't bother playing in a puny 250 the week before.

Further everybody is in USA for a month for IW and M. After Miami, due to Davis Cup, the players scatter all over the world. It is hard to expect them to travel back to USA again to play in a puny 250.

Those are the reasons why Houston tourney is dominated by Americans.
