Murray charges through to U.S. Open quarters

NEW YORK, (Reuters) – World number four Andy Murray  is already familiar with the added burden of expectation as he  has long carried the hopes of a British nation counting on him  to snap a 75-year grand slam drought.

Murray, vying to become Britain’s first grand slam champion  since Fred Perry won the U.S. Open in 1936, may have his best  shot yet but his quest now carries an added challenge.

After two days of persistent rain halted play at the last  grand slam of the year, Murray now faces a physical and mental  test of having to possibly play four matches in five days  before he can be crowned champion.

He will only get a day off if he makes the final, which  tournament organisers earlier decided would be played on Monday  instead of the originally planned Sunday.
