( CNN ) -- It 's been three years since Tommy Haas has reached an ATP Tour final , and the former world No . 2 's wait for a 13th career title was extended on Saturday . The 34-year-old rolled back the years on home soil this week when he stunned top seed Jo Wilfried-Tsonga at the Munich Open , but his tournament has now ended with a straight-sets defeat by 2010 runner-up Marin Cilic in the semifinals . Haas , who has overcome two career-threatening injuries in the past decade , was runner-up in the clay event in 2000 and had been on course to reach his first final since winning another German tournament , the Halle grass-court championship in 2009 . But Croatian Cilic triumphed 6-3 6-4 as he won 89 % of his service points to set up a clash with Germany 's Philipp Kohlschreiber on Sunday . `` It was my best match of the week , '' the 23-year-old third seed told the ATP website after beating a player who has reached four grand slam semifinals but needed a wild-card to enter this week . `` I played and served extremely well . I believe he did n't reach deuce on my serve . Tommy played really well this week and I went into the match with thoughts of that . It made good preparation for everything . '' Haas had also defeated former Australian Open finalist Marco Baghdatis on his way to the last four , but the world No . 134 lost in 75 minutes to a man seeking to win an ATP Tour title for the fourth successive year , owning six overall . Kohlschreiber , the 2007 Munich champion , will also be seeking his seventh title after beating Spanish second seed Feliciano Lopez in the second semifinal . The 28-year-old , who has also been a winner and runner-up at Halle , won 6-2 6-7 ( 4-7 ) 6-4 . In Portugal , Kaia Kanepi won her second WTA Tour title by beating Spain 's Carla Suarez Navarro 3-6 7-6 ( 8-6 ) 6-4 in Saturday 's final of the Estoril Open . The Estonian sixth seed had a six-week injury layoff after her maiden victory in Brisbane in January , but has battled back after losing first-round matches in Miami and Indian Wells . In the men 's event , defending champion Juan Martin del Potro of Argentina will play French second seed Richard Gasquet in Sunday 's final . In Belgrade , Italian second seed Andreas Seppi will take on France 's Benoit Paire in Sunday 's final of the Serbia Open . Seppi beat Argentine fourth seed David Nalbandian , while in another three-set match Paire upset Spaniard Pablo Andujar -- who was top seed in the absence of defending champion Novak Djokovic , who is mourning the recent death of his grandfather .
