Fresh from winning the Adelaide International title, Tomas Machac begins his Australian Open campaign. Round one of this outdoor hard court tournament sees him face fellow unseeded player Grigor Dimitrov. Time for our match prediction.
In round two, either 31st seed Stefanos Tsitsipas or unseeded Shintaro Mochizuki will be faced.
He's won five of his six matches played this year and the last five in a row. The last of those victories saw him defeat Ugo Humbert in the Adelaide final. His only loss this year was to Jiri Lehecka in Brisbane.
His one previous match against Dimitrov was a win in the indoor hard court tournament in Vienna in 2024. Machac has made it to round three of this Grand Slam for the past two years and will want another good run.
Grigor Dimitrov would probably just want an injury-free year above anything else. Last year saw him play in Brisbane and this tournament and he lost via retirement in both events. A further three retirements took place in the rest of the year. He only played 15 matches in 2025.
Dimitrov is 45th in the live rankings, 21 places below his opponent. He's 1-1 in matches this year and thankfully there's been no retirements.
We tip Machac to win.
