Roberto Bautista Agut stunned nineth-seeded Jo-Wilfried Tsonga 6-3, 6-4 to reach the Shanghai Masters semifinals on Friday.
The Spaniard broke his French rival three times in the first set and once in the second as he raced through in one hour 12 minutes at the Qi Zhong Tennis Center.
Bautista Agut's third win in a row over Tsonga, the last year's runner-up, pitches him into a semifinal against either defending champion Novak Djokovic or Germany's Mischa Zverev.
The 28-year-old world No. 16 is now into the last four at a Masters tournament for the second time after his Madrid Masters semifinal spot in 2014.
