Novak Djokovic is concerned that his physical conditioning might be a setback as he aims for his 25th Grand Slam singles title at the US Open.
The 38-year-old Serbian star kicked off his latest pursuit of success on Sunday, defeating US teenager Learner Tien 6-1, 7-6 (7/3), 6-2 in 2 hours and 25 minutes at Arthur Ashe Stadium.
However, Djokovic, who took an extended medical timeout to address a blister on his right foot between the second and third sets, expressed concern about a sudden dip in stamina during the second set.
“I started strong, finishing the first set in just over 20 minutes and felt great,” said Djokovic.
“But then, some long games began the second set… I was really surprised by how poorly I felt physically in the second set.
“We had long rallies, and I made numerous unforced errors, allowing him back into the match.
“There are positives, but also aspects I hope to avoid concerning my physical condition during the second set.
“It’s slightly worrying. I don’t have any injuries, but I struggled to maintain energy in prolonged rallies and recover after points.”
‘Still have the drive’
Djokovic hasn’t played since his Wimbledon semifinal loss last month, opting out of the ATP Masters events in Toronto and Cincinnati to focus on the US Open.
Despite showing some rustiness on Sunday, Djokovic delivered glimpses of the brilliance that has defined his illustrious career.
Djokovic looked in a hurry from the start, quickly securing the first set 6-1 with impressive winners.
Tien found hope in a sluggish second set from Djokovic but was unable to convert a break point that could have tied the match.
Instead, Djokovic held serve to level at 5-5 in the second set and asserted control by claiming the tiebreak, using smart net plays and varied techniques to challenge Tien.
Djokovic took a medical timeout to treat his right foot before starting the third set.
The pause seemed to energize Djokovic, who quickly took a 5-1 lead, leaving Tien struggling.
Tien managed to save a match point on Djokovic’s serve before breaking back for 5-2.
But Djokovic quickly regained momentum, breaking back to secure the victory.
“I wish I had Learner Tien’s youth; when you’re in your late 30s, it’s about conserving energy for what’s important,” Djokovic told the crowd.
“I still have the flair and drive, and you all give me the energy. Hopefully, I can continue,” he added.
Djokovic will face US qualifier Zachary Svajda in the second round.
