Aryna Sabalenka said she is determined to look ahead, rather than dwell on a difficult past few months, after beginning her US Open title defence with a 6-2, 6-4 victory against Camila Osorio.
Sabalenka’s No 1 ranking is at risk after failing to reach a final for four months, with Elena Rybakina having a strong chance of taking top spot.
Sabalenka produced a professional opening performance, serving well and overpowering Osorio from the baseline.
She eased through the first set, and quickly rolled through the concluding three games of the second to close out the match.
The Cincinnati Open champion Arthur Fils, meanwhile, endured the biggest upset of the second day at Flushing Meadows: he was defeated 4-6, 7-6 (3), 6-1, 6-4 by the former world No 3 Stefanos Tsitsipas.
Fils, the 10th seed, arrived in New York considered one of the title contenders in an open men’s draw, but after leading 6-4, 5-2 the Frenchman balked while attempting to serve for the second set.
Once he allowed Tsitsipas back into the match, the Greek served and struck his forehand brilliantly until the end, while Fils failed to regain the intensity and quality with which he began the match.
It is an enormous result for Tsitsipas, twice a grand slam singles finalist, who fell as low as No 88 in the ATP rankings this year and now sits at No 53.
The 28‑year‑old recently chose to split from his father, who had coached him on‑and-off since his childhood. Their relationship had become increasingly tense this year, leading Tsitsipas to declare that he does not intend to work with him again. This result is a significant step forward as he tries to re-establish himself.-Guardian
