The Madrid Masters will take place over two weeks rather than one from 2021, says tournament director Feliciano Lopez.
This year it was one of the events that fell victim to the coronavirus crisis, with it cancelled relatively late after originally being rescheduled.
However, they have put that extra time to use and accomplished what they say has been a long-term goal of expanding.
“We’re happy to have achieved the goal of becoming a two-week tournament”, said Feliciano López, director of the Mutua Madrid Open.
“We sought this expansion and it is well-deserved, necessary and will allow us to enjoy the best tennis in the world at the Caja Mágica for a few more days.
"I’m sure that both our sponsors and all the fans will welcome this news with open arms, as well as the city of Madrid, which will receive more visitors for a longer period of time.”
Next year the Madrid Open will start on April 27 with the WTA qualifying round. The first round of the women's main draw will then commence on April 29.
The ATP qualifiers will begin a day later on April 30, with the first round starting on May 2.
