• Serb hopes to take advantage of wide-open men’s draw

• Elena Rybakina has eyes on No 1 world ranking

Novak Djokovic said he was as prepared as he could be for the US Open as he attempts to take advantage of the wide-open men’s draw and battle for a potential 25th grand slam title.

Djokovic arrived in New York having competed only once after his semi-final run at Wimbledon, losing in his opening match of the Cincinnati Open to Thiago Agustín Tirante while struggling with the humidity. However, he now sees the silver lining in that defeat, which he believes gave him the time to make sure he was in optimal shape for the US Open. “I don’t like early losses anywhere, to be honest, but it gave me time to be prepared for US Open in a most adequate way,” he said. “I had almost a few weeks, actually two weeks, to really train and get my body and mind into the right state, prepared for what’s coming up.

Defending champion arrives at Flushing Meadows in poor form and with a host of challengers looking to usurp her

Under any normal circumstances Aryna Sabalenka would not have lost her third-round match at the Cincinnati Open last week. For all of her unforced errors, indecisiveness and the obvious tension surrounding her tennis, the world No 1 had led the unheralded Sára Bejlek 5-1 in the first set tie-break and then 4-1 in set two. She gave herself more than enough chances to close out a comfortable win.

Instead Sabalenka returns to New York trying to find a path through her greatest crisis since she first reached No 1 in the rankings more than three years ago. That straight-sets loss in Cincinnati extended a mediocre 17-7 record dating back to the beginning of April during which she has not reached a final. She has just one more chance to turn her fortunes around as she tries to claim her first grand slam title of the year at the US Open, the tournament she has won on the last two occasions.
