Murray through after tough test

The British number one, who is seeded 11 and received a first round bye, lost the first four games of a fractious match but recovered to progress 3-6 6-3 6-3.

Both players reacted angrily to various decisions by the officials but Murray was the more composed by the end as world number 85 Melzer slipped from his early high standards.

Melzer, conqueror of Marat Safin in the previous round, raced out of the blocks to open up a 4-0 lead before Murray finally got himself into the match by breaking back.

The 21-year-old Scot then held and had a break point on Melzer's next service but in a fraught game that went to four deuces, the Austrian eventually prevailed.

Murray swore loudly in frustration at one shot and also complained to the umpire when he felt a let was not picked up by net sensors. Melzer held to finish off the first set with ease but Murray regrouped to start the next positively.

He took the first three games to take a clear advantage but almost immediately squandered it as Melzer, who also saw fit to complain over some decisions, rallied to pull back to 3-2.

Murray responded to break again and then closed out the set off his own service. With Melzer having lost the zip of the first set, Murray began to play with more confidence and broke in the third game of the final set to establish a winning position.

Both players continued to show frustration at various aspects of their games but Murray was not broken again and booked his place in the next round with another service break.
