Canadian second seed Milos Raonic is through to the final of the St. Petersburg Open after beating Roberto Bautista Agut in straight sets.
Raonic, who is looking to secure one of the final four qualifying spots for the season-ending ATP World Tour Finals in London, fired 17 aces on the way to a 6-2 7-6 (7-2) victory over the fourth seeded Spaniard.
"I'm pleased with my performance," Raonic said.
"I started well. In the second set he (Bautista Agut) played much better but I'm glad with how I managed to cope with this situation."
Raonic will be bidding for his seventh career title on Sunday.
To do so he will have to get past Portugal's Joao Sousa, who beat Austria's third seed Dominic Thiem 6-4 7-6 (7/5) in the day's other semi-final.
"I played a great match today," said Sousa. "I served well and that was the key for my win."
