On Monday, the morning after losing the final in Indian Wells, Calif., Roger Federer was off to Chicago to promote the Laver Cup before heading to Florida for the Miami Open.
Del Potro saved three match points and stopped Federer’s 17-match winning streak to win a Masters 1000 event for the first time.
Osaka, a 20-year-old who represents Japan, defeated Daria Kasatkina, also 20, 6-3, 6-2, at the BNP Paribas Open on Sunday.
Asked what it would mean to have two 20-year-olds in their first final in one of the tour’s top-tier events, Kasatkina said: “That we are coming. Very soon.”
