Briton Andy Murray fought back from a set down to come out on the winning side of a tough first round match at Indian wells tennis tournament. Murray fired an ace out wide on match point to overcome Argentina's Tomas Etcheverry 6-7, 6-1 and 6-4 in the latest in a string of impressive comebacks for the ageless scot. Murray dropped the tight first set and frustration with his play and some of the calls made by the electric line calling system threatened to boil over. But like he has so many times in his career, he roared back with help from his ferocious forehand in the second set to force a decider. The match then hinged on a marathon game at 4-4 in the third where Murray executed a perfectly placed half volley winner that sent Etcheverry running off the court in pursuit. Murray's sixth ace of the match sealed the win as he improved to 7-0 in deciding set matches this year. Next up is a meeting with Spain's Pablo Carreno Busta in the second round and three-time grand slam champion Murray said he is as hungry as ever. In late action, Austrian Dominic Thiem continued to struggle, losing a three set battle with unseeded Frenchman Adrian Mannarino 4-6, 6-4 and 7-6.
