Britain’s Andy Murray beat Hubert Hurkacz in three sets to claim his first win against a top-10 player this season and reach the second round of the Vienna Open.
Murray’s victory came after a two-hour-40-minute battle with the fifth seed and world number 10.
“My movement has been getting a little better with each match,” he said.
“It was a good match that could have gone either way. It was a good win in tough circumstances.”
The 34-year-old added: “A lot of my movement is about anticipation and when you’re not playing many matches – like I haven’t been in recent years – you don’t read the play quite as well.
“Now I’m starting to see the ball a little earlier and starting to react a little quicker, which means I will start to chase more balls down.”
Murray’s win followed defeat for compatriot Dan Evans, who was beaten in straight sets by Spanish teenager Carlos Alcaraz.
Success for Murray was his first in three attempts this year against Poland’s Hurkacz.
The Scot lost to the 24-year-old in Cincinnati and Metz, both by the same 7-6 (7-4) 6-3 scoreline.
The former world number one will now face 18-year-old Alcaraz, who he beat in Indian Wells last month.
Alcaraz earlier denied Evans an all-British second-round tie with Murray.
Evans, 31, twice broke back to level in the first set before a costly service game – from a 40-15 lead – saw Alcaraz break again for the opener.
Evans bounced back with an early break to lead 3-1 in the second set, but lost five games in a row to go down 6-4 6-3.
