"I'm playing Juan Monaco today and Kei Nishikori on Sunday. I'm playing with good players and I am absolutely fine in practice.
"I've held my own and I've played well. I'm not as far away as I maybe thought I was a couple of weeks ago."
Friday's draw was kind to Murray. In the first round, he faces 29-year-old Go Soeda of Japan, the world No112. The winner faces a qualifier in the second round, while Feliciano Lopez and John Isner are seeded to meet Murray in the third and fourth rounds. Thereafter he could play Roger Federer in the quarter-finals, Rafael Nadal in the semis and Novak Djokovic in the final.
"After a relatively cool week, the temperature here moved into the 30s yesterday and is set to climb 10 degrees next week. It will be hot when I play on Tuesday and I need to get in the hours in those conditions," Murray said.
"Playing matches in these conditions is tough. Just being back and playing in front of a lot of people when you haven't done it for three months is different to playing on a court when there's no one there."
Djokovic looks to have been given the easiest draw and Federer the toughest. Radek Stepanek, Fernando Verdasco and Tsonga are all possible opponents for the Swiss before the quarter-finals. Nadal has the most challenging first round draw, against the 21-year-old Australian Bernard Tomic.
