Stan Wawrinka stayed on course to win a third successive Chennai Open title by beating Benoit Paire in straight sets and will face teenager Borna Coric in Sunday's final.
The world number four saw off the Frenchman 6-3 6-4 in Saturday's first semi-final to ensure he has still not dropped a set this week and needs just one more victory to land the ATP 250 tournament for a fourth time.
Top seed Wawrinka saved the only break point he faced and needed only two breaks of his own to stretch his winning run in this tournament to 11 matches.
The French Open champion needed only 65 minutes to get the better of Paire, who he combined with to win the doubles title in Chennai three years ago.
Wawrinka, who has now won 22 sets in a row in the Chennai Open, said: "I thought I played well and I am happy with my level.
"It's never easy to play against [Paire], but we always enjoy playing against each other, and it's nice to share this moment with a friend."
Coric reached his first ATP World Tour final courtesy of a marathon 7-6 (7-5) 6-7 (5-7) 6-3 triumph over 2015 runner-up Aljaz Bedene.
The 19-year-old Croatian is the youngest ATP World Tour finalist since Kei Nishikori in 2008 and the first teenager to progress to a final since Marin Cilic in the same year.
Coric powered down 17 aces to the Brit's 16 in a contest which could have gone either way, with Bedene unable to make his advantage count after moving a break up in the deciding set.
