Former world number one Andy Murray kept his 2021 season going with a straight-set win in the Stockholm Open first round.

The 34-year-old Briton was not troubled until Durasovic broke back for 3-3 in the second set, then dug deep to take a third match point in the tie-break.

Murray will face Italy's world number 10 Jannik Sinner in the second round.

After a one-sided opening set, Murray was tested by 354th-ranked Durasovic in a more competitive second, which lasted more than an hour.

In his previous outing, the Scot held seven match points before losing to Germany's Dominik Koepfer in Paris and he could not serve out his first two against Durasovic.

But Murray ensured there would be no repeat of that drama as he secured victory on his opponent's serve at the third attempt.

Three-time Grand Slam champion Murray was watched by Esteban Carril, who is poised to join his coaching team next season.

US Open champion Emma Raducanu had a short trial with Carril last month, but the highly regarded Spanish coach is instead working with Murray in the Swedish capital this week.

If all goes well, Carril will join Jamie Delgado on Murray's coaching team on a permanent basis.

"It's another person with a fresh set of eyes and with a good reputation and good experience. That's why I wanted to try it out and see how it goes," said Murray, who is still rebuilding his career after serious hip surgery in 2019 and a series of subsequent injuries.

"These last few years have been tough for me and my team. I think having a little bit of space and distance is important."
