Tomas Berdych of the Czech Republic stretches for a running forehand during his first-round match against
Fernando Gonzalez of Chile at the Western & Southern Financial Group Masters Tournament in Mason, Ohio.
Berdych won the first set and took the match after Gonzalez, ranked 12th in the world, retired with a knee injury.
