Stefanos Tsitsipas has been defeated in an unexpected upset at the Indian Wells Masters tennis tournament.
The Greek tennis player lost in a tough three set battle to Nikoloz Basilashvili, who moves on to his first ATP Masters final four.
With this, the biggest win of his career, Basilashvili turns his desert fortunes around, battling past Tsitsipas 6-4, 2-6, 6-4 for a first career Masters 1000 final four.
The 29-year-old from Georgia beat Tsitsipas for the first time in three tries.
Basilashvili held at love to win the first set before Tsitsipas cruised through the second set.
In the third, Tsitsipas fell behind the baseline chasing a shot in the third game and came up limping. But he shook it off and went on to break Basilashvili and then held for a 3-2 lead.
Basilashvili won three straight games for a 5-3 lead. Tsitsipas served three aces to trail 5-4. Basilashvili pulled out an ace of his own to set up match point and produced another big serve that Tsitsipas couldn't return to close out the match in just over two hours.
Ranked 36th in the world, Basilashvili's previous biggest win came over then-No. 4 Juan Martin del Potro in the final at Beijing in 2018.
Ranked third, Tsitsipas has a leading 54 wins on the ATP Tour this year.
