2011: Andy Murray - Bangkok, Tokyo, Shanghai 2023: Daniil Medvedev - Rotterdam, Doha, Dubai Before Daniil Medvedev, the last tennis player able to win three titles, of which only one ATP 250, within three weeks was Andy Murray 12 years ago
Medvedev's recent run of form has been spectacular and to demonstrate just how special it was, the last time somebody did what he did in the past 3 weeks was 12 years ago.
Andy Murray won three trophies in three weeks 12 years ago and now Medvedev equalled that. There is a caveat to this milestone because both of them only won one ATP 250 event with the other two being more prestigious. In Murray's case it was Bangkok, Tokyo, and Shanghai while in Medvedev's case it was Rotterdam, Doha, Dubai.
The Russian defeated his good friend Rublev in the Dubai final to replace him as champion as Rublev was the defending champion. The most recent 3-week champion was Casper Ruud who won Bastad, Gstaad and Kitzbuhel in 2021. However, all of those were ATP 250 event hence why it doesn't count in this specific regard.
