Murray vows to adapt game for Australian Open as Nadal participation put in doubt
Andy Murray vowed to learn from his defeat after his winning start to 2019 was ended abruptly at the Brisbane International.
Murray, who continues to be affected by a long-term hip injury, overcame James Duckworth in his first match since September on New Year's Day, but 24 hours later was beaten comprehensively by fourth seed Daniil Medvedev.
The 31-year-old, who has slipped to 240th in the world rankings, lost his second-round match 7-5 6-2 to Medvedev, who fired 16 aces to set-up a quarter-final with Canadian Milos Raonic on Friday.
"If you're not serving as well, or if you're not moving as well, the better players exploit that," Murray said. "He is a top player and is able to do that.
"So I need to try and find a way of working out how to get around some of the things I struggle with a little bit now and I'll try to do that."
