Taiwan had a split day at the Cincinnati tennis tournament — a strong win for Chan Hao-ching, an early exit for Liang En-shuo.

• Chan Hao-ching and Australian partner Maya Joint beat Olympic doubles champion Sara Errani and Leylah Fernandez in straight sets to reach the quarter-finals.
• The pair blew a 4-0 lead in the first set, held their nerve in the tiebreak, then ran away with the second set by winning six games in a row.
• It follows their opening upset of the No. 8 seeds, so the new partnership is clicking fast.
• Liang En-shuo and Japan's Shuko Aoyama were beaten easily by the seventh seeds, ending a run that had taken them to the last four at both the French Open and Wimbledon this summer.
• Cincinnati is the last big tune-up before the US Open at the end of August.

Outlook: Chan and Joint carry real momentum into the quarter-finals and into the US Open, while Liang's pairing needs to regroup quickly.
