Britain’s Andy Murray claimed a straight-set win over David Goffin to reach the second round of Indian Wells.
The three-time Grand Slam champion, 36, revealed at last month’s Dubai Tennis Championships he is not planning to “play much past this summer”.
In his first match since then, Murray raced to a routine 6-3 6-2 victory against the Belgian qualifier.
However, Britain’s Katie Boulter and Jack Draper suffered first-round defeats in California.
Murray’s future has come under increased scrutiny after struggling for wins in recent months, winning just two of his eight matches before Indian Wells.
However, the former world number one looked in good form as he sent down two aces to seal a 34-minute opening set against Goffin.
Murray took an early advantage in the second set and broke again to go 5-2 up and serve out the win with an ace. He will next face Russian fifth seed Andrey Rublev.
“That’s the best I’ve served here,” said Murray, who is making his 16th appearance at Indian Wells.
“I’ve always struggled serving, certainly the last 10 years or so, when I’ve been here for whatever reason.”
Murray told BBC Sport: “The conditions here this year definitely help. It’s not the same as it has been for the most part of my career here – it’s significantly faster than before, which I like. I wish it had been like that for the past 15 years or so.”
