Carlos Alcaraz impressed on his return to tennis with a straight-sets win over Russia's Roman Safiullin in the first round of the US Open.

Alcaraz has not played a competitive singles match since withdrawing from the Barcelona Open in April with a wrist injury that forced him to miss the French Open and Wimbledon.

The severity of the injury, which did not require surgery, meant Alcaraz was a doubt for the US Open but he entered Flushing Meadows and showed with his 6-4 6-4 6-4 win over Safiullin that he cannot be dismissed to defend his title from last year.

Watched on by rapper Travis Scott, who helped design Alcaraz's brown outfit for the US Open, there was plenty of attention on the seven-time Grand Slam champion's serve and groundstroke speed, given he had not played competitive singles for over four months.

He needed to save two break points from Safiullin in his opening three service games before breaking himself in the eighth game which proved enough to claim the opening set.

Alcaraz was broken at the start of the second set but broke back immediately and upped his intensity to break in the eighth game again and go on to win the second set.

After an early break in the third set, Alcaraz never came under threat on his serve and continued to move well while maintaining a high level on both wins to see off the tricky Russian.

One of the biggest threats in Alcaraz's half was Arthur Fils, after he won the Cincinnati Open title last week, but he was knocked out of the tournament by Stefanos Tsitsipas in a 4-6 7-6 (7-3) 6-1 6-4 defeat.

Like Alcaraz, Aryna Sabalenka started her US Open title with a straight-sets win as she beat Colombia's Camila Osorio 6-2 6-4.

Sabalenka is bidding to become the first player to win three consecutive US Open titles since Serena Williams in 2014 and was put under serious pressure by Osorio in the second set.

"Camila is a tough opponent but I was ready to do whatever it takes to get the win," she told Sky Sports Tennis .

"I really enjoyed the atmosphere and support. A fun and tough match but happy to get through in straight sets."

Sabalenka's form has been questioned after losing in the last 16 in her last three tournaments - Wimbledon, the Canadian Open and Cincinnati Open.
