Zhang Shuai’s drought-busting week came to a shuddering halt as Paula Badosa continued her own resurgence in a 6-1, 7-6 (4) victory to make the China Open semifinals on Thursday. The 19th-ranked Spaniard has won 28 of her last 35 matches dating to May and made the semifinals of three of her past five tournaments. There was also a run to the U.S. Open quarterfinals last month.
