PARIS -- Sam Querrey reached the second round of Roland Garros for only the second time Sunday with a straight-sets win over Lukas Lacko. The top-seeded at No. 18, Querrey said the only thing he is focused on was not getting down on himself. Three years ago he admitted to all but tanking a match in Paris.

“Didn’t care if I won or lost,” said Querrey, who had only won one match during the clay-court season. “I just wanted to go out there and have a good attitude and play positive and big…Felt great. I was upbeat. My footwork was good. Decisions were good. It was probably my best match all year.”
