Andy Murray saved three match points and won a final-set tie-break to beat Lorenzo Sonego 4-6 6-1 7-6 (7-4) in the first round of the Qatar Open.
The Scot lost his opening service game to love as Sonego went on to claim the first set before Murray raced through the second to level the match.
Murray saved three break points when 4-5 down in the decider and then came from 3-0 down in the tie-break to win.
"It was really tough," 35-year-old Murray told Amazon Prime.
"We've never played or practised against each other. I didn't know exactly how the match was going to go and took a while to get used to his game.
