Pune - Top seed Marin Cilic of Croatia crashed out of the ATP Tour's Maharashtra Open on Friday, losing in three sets to lowly-ranked Frenchman Gilles Simon at the semi-final stage.
Cilic, the world number six and overwhelming pre-tournament favourite, comfortably took the first set 6-1, but Simon stunned the 2014 US Open champion to win the next two 6-3, 6-2.
Simon, the world number 89, will play either compatriot Benoit Paire or South Africa's Kevin Anderson in Sunday's final.
The hard court event, which has total prize money of $500 000, is taking place in the western Indian city of Pune.
It is viewed as a key warm-up event for the first Grand Slam of the year, the Australian Open, which starts in Melbourne on January 15.
