MIAMI (Reuters) - Wimbledon champion Andy Murray appeared to be adjusting just fine to life without coach Ivan Lendl, storming into the fourth round of the Sony Open on Sunday with 6-4 6-1 win over Spain's Feliciano Lopez.

After getting the defence of his Sony Open title off to a shaky start with a three-set win over Matthew Ebden on Friday, the sixth seeded Scotsman needed just 73 minutes on a sweltering centre court to claim a convincing decision over the 32nd ranked Spaniard.
