Key Storylines

Paula Badosa returns home as World No.2: Last year, Badosa made good on a main draw wildcard to becoming the first Spanish woman to make the Madrid semifinals and she hasn't looked back. Twelve months on, the 24-year-old has rocketed up 60 spots in the rankings to sit behind Swiatek at No.2. Badosa's consistency has been remarkable. She has made the quarterfinals or better in seven of her last 11 events, including recently at Indian Wells and Stuttgart. 

Chasing down Swiatek: The Pole has a lead of over 2,000 points on the field and she will have an opportunity to add to that tally in Madrid, where she bowed out in the Round of 16 last year. But having won Rome and made the Roland Garros quarterfinals last season, Swiatek will be defending a large set of points over the remainder of the clay season. That opens up some potential opportunities for players like Badosa (who skipped Rome last year), Maria Sakkari, and Anett Kontaveit to close the gap over the next weeks with deep runs in Madrid and Rome.

Naomi Osaka gets her clay season underway: With the confidence gained from her run to the Miami Open final to close out the spring hard-court season, Osaka returns to Madrid. Three years ago, the former No.1 made the quarterfinals at the Caja Magica.

Monica Puig returns: The 2016 Olympic champion is set to make her return to the tour after undergoing shoulder surgery last summer. Having also battled an elbow injury, Puig has played just three matches since 2019.
