Australian Open: World Number One Reaches The Second Round
World number one, Andy Murray (Britain) won his first Grand Slam match, beating world number 95, Illya Marchenko (Ukraine) in a tough match that ended after two hours, 48 minutes.
Murray was clearly frustrated as Marchenko gave him a tough time. Murray won the match 7-5, 7-6 (7-5) 6-2.
The 29-year-old Wimbledon champion faces Russia's Andrey Rublev next.
Murray made a nervy start and lost the first game with three double faults and a forehand error, but he took control to serve for the set at 5-3.
However, Marchenko broke the Scot again to draw level, only for Murray to raise his intensity and take the set after 55 minutes.
The Ukrainian, 29, hit a series of powerful forehands and deft volleys to take the lead in the set.
Murray had to fight hard to force a tie-break, but once again the top seed did enough when it mattered to win the set after a marathon 76 minutes in hot conditions.
