Is Sam Querrey ready for the big stage?

Sam Querrey, the 20th seed and last remaining American left in the men's tournament, has become a bit agitated about not getting a match on the Arthur Ashe Stadium's show court.

Today he gets his wish against Switzerland's Stanislas Wawrinka, seeded 25th, with a spot in the quarterfinals up for grabs.

Querrey has played all three of his matches on the No. 2 court at Louis Armstrong Stadium.

John Isner played twice at Louis Armstrong Stadium, then lost on Sunday night at Ashe. No. 19 Mardy Fish played on the Grandstand court once and Armstrong twice before a loss to Novak Djokovic on Monday, also at Ashe.

Querrey has been upset with the scheduling and said he feels it definitely could hurt the American players to not get a feel for Ashe.

So far, Querrey seems to be right with Isner and Fish both losing. Querrey gets his shot to win at Ashe in what could be the biggest match of his young career.
