Federico Delbonis pulled off a huge upset at Indian Wells as he beat Andy Murray 6-4, 4-6, 7-6(3) in the third round on Monday.
Murray, who is still searching for his first title of the year, arrived in California on the back of a strong showing in the Davis Cup which was his first appearance since taking time off following the birth of his daughter in early February.
The Scot looked a rusty early on in the first set and Delbonis broke him in the third game to take a 2-1 lead. Murray broke back in the next game, but Delbonis surged ahead and clinched the set after breaking the world number two for a second time.
However, Murray refused to go down without a fight and broke the Argentinean in the 10th game of the second set to level matters at a set apiece.
Heading into the third set, Murray appeared on track to take the decider comfortably as he raced out to a 4-1 lead after breaking Delbonis in the fourth game.
Delbonis though came roaring back and broke Murray to make it 5-5 before consecutive breaks set up a tie-break. It was Delbonis who was able to dig deep when it matter and stunned the two-time grand slam winner.
Delbonis will either face Gael Monfils or Albert Ramos-Vinolas in the fourth round.
