Cincinnati, August 23: Former world number one Andy Murray said he can "definitely improve" after winning his first match of the year at the ATP Western & Southern Open.
Murray had not featured on the ATP Tour since claiming the European Open in Antwerp last October, however, the three-time grand slam champion made his return on Saturday (August 22).
In Cincinnati, Murray - who saved a set point in the first set tie-break - outlasted Frances Tiafoe 7-6 (8-6) 3-6 6-1 in the opening round of the Masters tournament.
"I thought I moved well today," two-time Cincinnati champion Murray said after two hours, 28 minutes on court, with the US Open on the horizon this month.
"That was probably the thing I was most happy with and probably the thing I was most apprehensive about going into the match.
"I thought I moved pretty well. My tennis could have been better.
"I did some things well at the end, but I could definitely improve in terms of my game."
Next up for Murray is fifth seed Alexander Zverev as the 33-year-old steps up his preparations for the US Open in New York amid the coronavirus pandemic.
Murray added: "[Zverev has] obviously been up at the top of the game for a number of years now.
"It will be a good test for me, for sure… He moves well for a big guy, solid off the ground. [He] has struggled at times with his serve. When he's serving well, he's obviously one of the top players in the world."
