The Indo-Swiss team dubbed "Santina" were hoping to win four majors in a row after following up last year's Wimbledon and U.S. Open triumphs with victory in January's Australian Open.
But the top seeds appeared all at sea on a gloomy day at Roland Garros and their bid to complete the 'Santina Slam' ended after the Czechs blasted a service return winner to break Hingis in the final game.
Hingis and Mirza were left fuming at the umpire after a call went against them as they trailed 4-1 in the second set. Mirza tossed the ball in anger but the duo failed to win the argument, or the match, leaving Krejcikova and Siniakova to celebrate a memorable victory.
