Sabalenka edges Raducanu in marathon clash in Cincinnati Open, Fritz cruises past Sonego

World number one Aryna Sabalenka kept her Cincinnati Open title defence alive by claiming a 7-6(3) 4-6 7-6(5) victory over Emma Raducanu in a marathon third-round clash on Monday, while Taylor Fritz advanced with a straight-sets win over Lorenzo Sonego.

Fresh off their third-round clash at Wimbledon last month, Sabalenka and Raducanu produced another epic contest, featuring a 13-deuce game in the third set, before the Belarusian sealed victory in three hours and nine minutes.

Sabalenka relied on her trademark powerful serve to hold firm in the key moments, winning two tiebreaks to take her tally to 18 for the season, the most by any women's singles player in the professional era.

Despite the defeat, Raducanu seems to be finding her best form just in time for this month's U.S. Open at Flushing Meadows, where she triumphed in 2021. The Briton outscored Sabalenka in total points won, 125–123.

"I'm really happy to see her healthy. I can see she's improving," Sabalenka said of Raducanu.

"Happy to get through this match. I really hope tomorrow I have a day off."

Sabalenka next faces Spain's Jessica Bouzas Maneiro in the last 16.

Elsewhere, Anna Kalinskaya stunned American fifth seed Amanda Anisimova 7-5 6-4 for her third win against a Top 10 opponent in the season. She will face fellow Russian Ekaterina Alexandrova in the next round.

After a one-hour delay caused by a power outage, fourth seed Taylor Fritz defeated Italy's Sonego 7-6(4) 7-5.

The 27-year-old American did not face a break point and capitalised on his lone break opportunity before serving out the match, sealing the win in two hours and eight minutes.

Former champion Madison Keys booked her place in the last 16 with a 6-4 6-0 win over Japan's Aoi Ito, edging a tight first
