ATP Finals hopefuls Andrey Rublev and Denis Shapovalov will meet in the semi-finals of the St Petersburg Open after claiming straight-sets victories on Friday. 

Rublev holds the final automatic qualification spot for the season-ending tournament in London next month following a 6-2 6-1 win over Cameron Norrie. 

The third seed was a cut above Brit Norrie, improving his record to 32 victories and just seven defeats this year, which has included three titles. 

Shapovalov, meanwhile, beat Stan Wawrinka 6-4 7-5 in a battle between youth and experience, the 21-year-old Canadian winning 84 per cent of his first-service points. 

Milos Raonic defeated fellow seed Karen Khachanov 6-1 7-6 (7-1) and will face Borna Coric in the other semi-final, the Croatian having ousted Reilly Opelka in straight sets.

Top seed Alexander Zverev moved into the last four of the Cologne Indoors on home soil, beating South African qualifier Lloyd Harris 6-4 3-6 6-0. 

Zverev will come up against Alejandro Davidovich Fokina in his third semi-final of the year after the unseeded Spaniard got past Dennis Novak 6-3 2-6 6-3. 

Roberto Bautista Agut and Felix Auger-Aliassime will do battle for a place in the final following wins over Hubert Hurkacz and Radu Albot respectively. 

Marco Cecchinato and Lorenzo Musetti will be hoping to contest an all-Italian Sardegna Open in their homeland after advancing to the last four on Friday, along with Serbian duo Laslo Djere and Danilo Petrovic.
