Tennis-Murray knocked out at Cincinnati by France's Chardy

MASON, Ohio Aug 16 (Reuters) - Olympic champion Andy Murray was knocked out of the Cincinnati Open in the third round on Thursday losing 6-4 6-4 to France's Jeremy Chardy.

Murray, the defending tournament champion, never looked himself as he was broken in the seventh game of the first set by Chardy, who is in the draw as a lucky loser.

Neither player could hold serve in the opening five games of the second set but Chardy held firm to go up 4-2 and never looked back.

Earlier, American Mardy Fish defeated Czech Radek Stepanek 6-3 6-3 and Argentine Juan Martin del Potro fought past Serb Viktor Troicki 7-6 2-6 6-1. (Editing by Frank Pingue)
