Andy Murray insists he is more interested in winning tennis titles than climbing the world rankings.
Winning the Miami Masters would see the world number three leapfrog Roger Federer and move into second spot.
However, the Scot who faces Bernard Tomic, said: "It's not something I'll be thinking about when I play my first match.
"It'd be a nice thing to do but getting to number two isn't a goal of mine."
Federer is not in action in Miami, nevertheless Murray believes adding to his tennis titles is more important than rankings.
"I'd rather try to focus on winning an event and get there by deserving it rather than working out exactly how many points you need or reaching a semi-final or whatever it is," he said.
"The one thing it does help with, if you get to number two, it's seedings for the bigger events and that's why it would be of benefit to me."
Australian Tomic earned the right to face Murray in the second round at Miami with victory over qualifier Marc Gicquel.
And Murray expects the 20-year-old to provide a stern test in the second round clash.
"He's very unpredictable and has a very unorthodox game and is extremely talented," said Murray.
"He uses a lot of variety and has very good anticipation. So, it's a very tough first match."
