Andy Murray eased through his first-round match at the Indian Wells Masters with a 6-3 6-2 win over Frenchman Adrian Mannarino.

Murray faces Spanish teenager Carlos Alcaraz in the second round.

"I thought my mentality was good. I fought for every single point. That was the goal coming into the match and it got me the win," Murray said.

"It's been four years since I was last here. I think it's one of the best places to play tennis on the ATP Tour.

"It's been a tough road to get back and it was so nice that so many people managed to come out and support today. I really enjoyed it."

Murray came into the match "back in the good books" at home after his misplaced tennis shoes and wedding ring were found in Indian Wells.

In his first appearance in the United Since since a thrilling defeat at the US Open to Stefanos Tsitsipas, Murray wrapped up the win in one hour and 24 minutes.

He broke Mannarino, who is ranked 51st in the world, to seize a 4-2 lead in the opening set and then clinched it when his 33-year-old opponent mishit an attempted smash.

Murray whacked a forehand winner to earn the key break in the second set and saved a break in the final game before Mannarino fluffed a drop shot.

The win set up a meeting with 18-year-old Alcaraz, who Murray plays for the first time in his career.

"I think Alcaraz is really, really good," Murray added. "I think he's got a good chance at it."
