Germany's Dustin Brown beat sixth-seeded Sam Querrey 6-2, 4-6, 6-4 Thursday to complete a rain-delayed match from a day earlier, advancing to the quarterfinals of the Hall of Fame Tennis Championships.
Brown upset Rafael Nadal earlier this month in the second round at Wimbledon.
On Wednesday, he led 4-3 in the final set and was up 15-love when play was halted because of rain. When play resumed, Brown held serve and closed the eighth game with consecutive aces. He won when his American opponent hit a backhand return long.
