MADRID - Felix Auger-Aliassime said “it’s crazy times for the elite of our sport” as the Canadian benefited from yet another retirement to set-up a Madrid Open final clash against Andrey Rublev on May 3.

Czech 30th seed Jiri Lehecka became the latest player to withdraw in the Spanish capital through injury, as he sustained a back problem and was forced to retire at 3-3 in the opening set of his semi-final against Auger-Aliassime.
