DELRAY BEACH, Fla. (AP) — Third-seeded Sam Querrey moved into the second round of the Delray Beach International Tennis Championships when fellow American Michael Russell retired with a left leg injury with Querrey leading 6-2, 2-2 Monday night.

Russell, trailing 5-2 in the first set, had the trainer on the court to work on his leg.

Besides for having to save one break point in the fourth game of the first set, Querrey played confident tennis throughout the 44 minutes he was on the court.

"I thought that was the best attitude I've had all year," Querrey said. "It's the most aggressive I've been all year.

"I was hitting second serve returns and taking cracks at them, and dominating with my forehand. It felt great."

The biggest upset came from 62nd-ranked Ivan Dodig of Croatia, who beat fifth-seeded Alexandr Dolgopolov of the Ukraine 6-3, 6-3.

Dolgopolov, who reached the Memphis quarterfinals last week, initially led 3-0 in the match.

From there, Dodig, a quarterfinalist here in 2011, reeled off nine straight games for a 6-3, 3-0 lead in the 57-minute match.
