Jo-Wilfried Tsonga's fine indoor form continued as he edged out Philipp Kohlschreiber to set up a Vienna Open final against fellow Frenchman Lucas Pouille.

Tsonga claimed his fourth title of 2017 in Antwerp last week and has emerged as a late contender for a place at the ATP Finals.

His bid to secure one of the two remaining qualifying spots was strengthened in Austria by a 7-6 (7-4) 7-5 victory over Kohlschreiber, his 10th win in succession against the veteran German.

As a result, Tsonga, who was the runner-up to Andy Murray in last year's Vienna final, now boasts a 20-2 record in indoor matches this season.

Pouille stands between Tsonga and another tournament success, the former having come from behind to beat Kyle Edmund 6-7 (7-9) 6-4 6-3 and reach his first ATP 500 final.

The two previous meetings between Tsonga and Pouille, including a final in Marseille this February, have resulted in 6-4 6-4 wins for the 2008 Australian Open runner-up.
