World number four Novak Djokovic booked his place in the final of Halle's ATP grasscourt tournamentu00a0 against Tommy Haas with an 7-6 (9/7), 6-4 win over qualifier Olivier Rochus on Saturday.
Having blasted his way past Jurgen Melzer in Friday's quarter-final, Djokovic was far from assured in the semi-final against a player ranked 136th in the world.
