The weight of the moment weighed immediately on the Czech as she surrendered her opening serve and in a whirlwind 10 minutes, she had lost the first three games.
Muchova needed a nerve-settling hold to stem the flow. It came in the fourth game and while she held break points in the ensuing game, she struggled to contain the errors, such was the pressure from the opposite end.
The first set was secured after 45 minutes and Muchova’s best intentions of starting with a clean slate in the second set were in disarray when Swiatek again opened up a 3-0 lead.
The Czech’s time was fast running out. Pegged into a corner she secured her first break of the match with a blazing forehand on the run and with the Chatrier crowd behind her, it set off a dramatic turnaround as she served out the set at the second time of asking.
Both women struggled to consolidate their advantage in a tension-filled final set.
Twice Swiatek fell behind a break only to dig her way out.
Having struggled on serve throughout the third, the top seed managed to break Muchova for the seventh time when the Czech's second serve found the net.
Swiatek crouched in relief and buried her head. Never had she been pushed so far in a major final. It made victory taste that much sweeter.
