Stockholm - Bulgaria's Grigor Dimitrov beat Italy's Fabio Fognini 6-3, 7-6 (7/2) to make the Stockholm ATP Tour final on Saturday to consolidate his bid to play in a first end-of-season ATP Finals.
Top-seeded Dimitrov climbed to fifth ahead of Marin Cilic in the race to qualify for the end-of-season ATP Finals in London next month with Roger Federer, Rafael Nadal, Alexander Zverev and Dominic Thiem having already confirmed their places.
In Sunday's final, Dimitrov will play defending champion Juan Martin del Potro after the giant Argentine, seeded fourth, defeated Spaniard Fernando Verdasco 6-7 (4/7), 6-4, 7-6 (7/1).
Del Potro, the 2009 US Open champion, will be looking to claim a 20th career title and become just the third Argentine player to reach the mark after Guillermo Vilas, who won 62 titles and Jose Luis Clerc who ended his career on 25.
