Alex de Minaur finally turned the tables on his toughest rival on Tour, beating Stefanos Tsitsipas 6-4, 3-6, 6-3 in the first round of the Mubadala Citi DC Open on Wednesday to begin his defence of the Washington title.
De Minaur Tsitsipas Washington 2026: A Lopsided Rivalry Reversed
It was far from a straightforward assignment. Tsitsipas had won 12 of the pair’s previous 13 meetings on the Lexus ATP Head2Head, giving De Minaur about as unfavourable a draw as a defending champion could face in round one. The Greek had also held the upper hand in their recent encounters, including their most recent clash in Miami back in March.
Tsitsipas actually looked the more dangerous player early, racing out to a 4-2 lead in the opening set. De Minaur answered by winning four straight games to snatch it 6-4. The World No. 51 Tsitsipas found another gear to level things at a set apiece, but De Minaur reasserted himself in the decider, closing out the match 6-3 behind his trademark court coverage and defensive resilience after just over two hours on Stadium Court.

Match Stats and De Minaur’s Own Words
Speaking afterward, De Minaur credited a change in his service tactics for finally cracking the code against Tsitsipas, noting that in the past his serve hadn’t held up well against the Greek but that switching things up “ended up working out for me” this time. He was candid that it wasn’t his cleanest tennis, but said he was satisfied to have found a way through a tricky, low-key affair just days after his wedding.
The win extends an impressive run of form at this level: De Minaur now leads the ATP Tour with 60 match wins at ATP 500 events since the start of 2023, ahead of Carlos Alcaraz (50-6) and Alexander Zverev (50-19) on that same list. He’s also improved to 28-14 on the season and is competing as a tour-level top seed for just the fifth time in his career.
Defending Champion Status on the Line in Washington
The win is especially meaningful given the venue. De Minaur arrives in Washington as the reigning champion, having saved three championship points last year to beat Alejandro Davidovich Fokina in an epic three-set final. Doing it again while dismantling a genuine bogey opponent sends a clear signal to the rest of the draw that his form from 2025 hasn’t gone anywhere.
What’s Next After De Minaur’s Tsitsipas Win in Washington
Up next for the Australian is a second-round meeting with 17-year-old countryman Cruz Hewitt, son of ATP No. 1 Club member Lleyton Hewitt, who was in the stands at Stadium Court to watch De Minaur’s win. It’s a storyline made for Washington: the defending champion against a teenage wildcard with one of the most recognisable surnames in Australian tennis, and with Hewitt Sr. watching from courtside once again.
De Minaur will be the clear favourite, but as Wednesday’s result proved, recent history in Washington counts for very little once the ball is in play.
