Feliciano Lopez and Marc Lopez beat Bob and Mike Bryan 6-4 6-7 6-3 to win the men's doubles title at the French Open.
The 15th seeds had never before won a Grand Slam tournament, whereas the Bryan twins were seeking their 17th Major title together.
Lopez and Lopez - who are not related - are the 11th different men's pairing to triumph in the last 11 Grand Slams.
Their win means that France's Nicolas Mahut will replace Brazil's Marcelo Melo as world doubles number one.
