Querrey withdraws from US Men's Clay Court
Fourth-seeded Sam Querrey withdrew from the U.S. Men's Clay Court Championship before his second-round match Thursday because of a strained right pectoral muscle.
Querrey , the top ranked American at No. 20 in the world, was about to play wild card Rhyne Williams of the United States when he decided to withdraw.
Querrey won't play again for three weeks and doesn't anticipate an extended layoff.
He said: ''Because it's gotten so much better since Monday I think it three days it will be almost 100 percent. I've got three weeks to get healthy and back on the clay.''
Querrey said his next event will be in Madrid.
