Play well or quit, Dinara tells big brother

ROME: Marat Safin should put his whole heart into playing tennis or quit, his top-ranked sister Dinara Safina advised on Monday.

Former world No 1 Safin has failed to win back-to-back matches in nine of his past 10 tournaments, often perishing despite being in a winning position.

The 29-year-old was knocked out of last week's Rome Masters in the first round by Tommy Robredo after throwing away a 6-2 4-1 lead and Safina suggested her brother should hang up his rackets immediately if he is unable to turn around his form.
