Australian Bernard Tomic will face defending champion Ivo Karlovic in the final of the Claro Open Colombia in Bogota after battling past Victor Estrella of the Dominican Republic 7-6 (7-2) 6-7 (5-7) 7-6 (7-5) in the semi-finals.
Tomic's appearance in the final comes three days after he split with his management company IMG, which was reportedly due to concerns over his off-court behaviour.
It will be the 21-year-old’s first ATP Tour final since January's Sydney International.
Tomic said: "It's always very tough when I play Victor, he's a fighter.
"I knew it was going to be a hard match, I tried to stay focused on my serve and get the win. Now I'm going for the title."
Tomic's career has taken a downward turn since making the fourth round of the 2012 Australian Open, a decline which has seen his ATP ranking slip from 27 to a current 124.
He withdrew in the first round of the Australian Open against Rafael Nadal and underwent double hip surgery shortly afterwards and then suffered a record 26-minute defeat on his comeback event at Miami.
Karlovic beat Czech fourth seed Radek Stepanek 6-4 3-6 6-4 in the second semi-final.
