“I think he’s very motivated so I hope I can show my best tennis.”
Murray had to come from a set down to beat Alcaraz on Sunday and also pulled off an underarm serve to help hold his service game in the second set.
The move didn’t go down well with some of the crowd at Indian Well, but Murray insists he may try it again.
“Certainly when guys are standing there to return serve now, it’s a smart play,” Murray said.
“It’s the first time I’ve ever done it in a match and I got the ace. I served three aces the whole match and one of them was the underarm serve.
“So maybe I’ll try it again in the future if guys are standing that far back.”
