Australian Open 2023
Venue: Melbourne Park
Dates: Jan 16-29
Stefanos Tsitsipas defeated Jiri Lehecka in straight sets to set up an Australian Open semi-final with Karen Khachanov. Greek third seed Tsitsipas reached his fourth Melbourne semi-final in five years with a 6-3 7-6 (7-2) 6-4 win.
Lehecka, of the Czech Republic, had been one of the surprise packages of the tournament having beaten two top-12 seeds to make the quarter-finals. The 21-year-old had previously never won a Grand Slam match.
Earlier on day nine, Russian Khachanov progressed to the final four of the Australia major for the first time when his quarter-final opponent Sebastian Korda was forced to retire with a wrist injury with the score at 7-6 (7-5) 6-3 3-0.
The other semi-final will be decided on Wednesday (Jan 25), when Ben Shelton and Tommy Paul contest an all-American quarter-final before nine-time champion Novak Djokovic faces Russian Andrey Rublev.
