“It’s just that the conditions in New York in comparison to here are very, very different,” Murray revealed. “Pretty much every ball that you hit in New York was between your waist and your shoulders.
“The court was quite quick, so it was sort of shooting through and it was like first strike tennis, really.
“Whereas here the balls are checking a lot and it is very bouncy. It was windy as well and it really can swirl a bit in that stadium, whereas at Flushing Meadows or Wimbledon, when you’ve got the roofs on the court, you don’t really get the wind in there.”
Elsewhere, Dan Evans and Cam Norrie won their respective matches to join Murray in the next round at Indian Wells.
The British duo are currently battling for the title of British number one, and Evans will face Diego Schwartzman while Norrie is set to take on Roberto Bautista Agut.
Both games are scheduled to take place tonight, and Evans can enter the world’s top 20 for the first time in his career with a win over the Argentine.
