BOGOTA - Australian Bernard Tomic will face defending champion Ivo Karlovic in the Bogota ATP final after edging Victor Estrella 7-6 (7/2) 6-7 (5/7) 7-6 (7/5) in Saturday's semi-final. Tomic's appearance in Sunday's final as a wildcard comes three days after he split with global management company IMG with reports blaming the divorce on concerns over his off-court behaviour. This is the 21-year-old's first ATP final since January's Sydney International. "It's always very tough when I play Victor, he's a fighter," said the Australian. "I knew it was going to be a hard match, I tried to stay focussed on my serve and get the win. Now I'm going for the title," added the Wimbledon quarter-finalist in 2011. Karlovic beat Czech fourth seed Radek Stepanek 6-4, 3-6, 6-4 in the second semi-final.–AFP
