Tommy Robredo of Spain and Kevin Anderson of South Africa rallied to semifinal victories Saturday, setting up a title match in the Grand Prix Hassan.
Robredo beat top-seeded Stanislas Wawrinka of Switzerland 1-6, 6-3, 6-2. Anderson, seeded second, downed third-seeded Martin Klizan of Slovakia 2-6, 6-4, 6-2.
This will be Robredo's first final since winning on outdoor clay in Chile two years ago. He will be going for his 11th career title.
"Stan was playing very well and fast during the first set," he said. "I continued fighting and it went better during the second set as well as in the third. I'm very happy to be in the final again here, 12 years after my first appearance in Casablanca."
Anderson has two career titles, both on outdoor hard courts. His previous title was last year at Delray Beach, Fla. He has never played Robredo.
"Tommy's been around for so long. I was watching him on TV growing up," Anderson said. "He's obviously a very experienced clay-court player and has had some terrific wins. I'm going to have to play very well."
