Andy Murray loses to 53rd-ranked Federico Delbonis

Andy Murray was upset in the third round of the BNP Paribas Open on Monday, losing 6-4, 4-6, 7-6 (3) to 53rd-ranked Federico Delbonis of Argentina.

Delbonis scored the biggest win of his career, outlasting the second-seeded Murray in a 2-hour, 46-minute struggle. Three years ago, Delbonis defeated then-fifth-ranked Roger Federer in the semifinals at Hamburg.

The left-handed Argentine rallied from 4-1 down in the third set, winning three straight games for a 4-all tie. He held serve to tie it 5-all and broke Murray in the next game to go up 6-5. Murray broke back to force the tiebreaker, but not without a fight by Delbonis, who trailed 15-40 and got to deuce before sending a backhand wide to let Murray even the set, 6-all.

Murray led 3-2 in the breaker before Delbonis reeled off five straight points to close out the match. Murray committed errors on the last three points, with his forehand landing wide on match point.

Victoria Azarenka, the 2012 Indian Wells winner, and third-seeded Stan Wawrinka were to play night matches.

Murray was competing in his first tournament as a father. His wife, Kim, gave birth to daughter Sophia on Feb. 7, a week after the Scotsman finished as the runner-up to Novak Djokovic at the Australian Open. Murray is the highest seeded man to lose so far in the desert event.

Also advancing was No. 8 seed Richard Gasquet, a 2-6, 6-2, 6-1 winner over Alexandr Dolgopolov, and No. 12 seed Milos Raonic, who beat 17th-seeded Bernard Tomic 6-2, 3-0 after Tomic retired because of a wrist injury.

On the women’s side, No. 7 seed Belinda Bencic was upset by Magdalena Rybarikova of Slovakia, 6-4, 3-6, 6-3, and 2008 winner Ana Ivanovic lost 6-2, 6-0 to 18th-seeded Karolina Pliskova, who improved to 4-0 in her career against Ivanovic. U.S. Open runner-up Roberta Vinci beat 17th-seeded Elina Svitolina of Ukraine, 6-1, 6-3.
