Andy Murray suffered the narrowest of defeats in a marathon match in the last 16 of the Qatar Open as he went down 7-6 (6), 6-7 (3), 7-6 (4) to Jakub Mensik.
It was the longest match in tournament history at three hours and 23 minutes, with all three sets going to tiebreaks. Murray was on the brink of a heavier defeat when trailing 5-2 and a double break down in the final set but roared back to win four games on the spin and somehow force a tiebreak.
However, the 36-year-old Brit lost that decider 7-4 to the 18-year-old, big-serving Czech star who reaches an ATP Tour quarter-final for the very first time.
Murray had finally ended his six-match losing streak that stretched back to October of last year when he battled past Alexandre Muller 6-1, 7-6 (5) in the first round on Tuesday and was defiant last week in quelling retirement talk abut rising star Mensik held his nerve to record an impressive win.
