With Koepfer matching him shot for shot, point for point, rarely was Federer comfortable. Even when Federer gained notable leads, they scarcely propelled him too far forward, but instead was forced to take yet more steps. Having lost a set point with Koepfer serving at 4-5 in the first set, Federer went up 3-1 in the tiebreak, only to drop the next three points. But a Koepfer double-fault at 4-5 gave Federer just enough of a cushion to win the tiebreaker on this third set point. In the second set, Federer was up 2-0, served at 3-2 – and was broken at love. Koepfer dominated the tiebreaker.
And when Koepfer grabbed 2-0 and 4-3 leads in the third, he appeared likely to take control. In one rally after another, Koepfer drove deep off both sides, frequently running around his backhand to rip forehands. With a deep enough squint, the sight of a young lefthander pushing Federer into corners was reminiscent of all the times Rafael Nadal had tormented Federer with that sequence. But even more, Koepfer’s comfort dictating the tempo of many a rally was summoned memories of Federer’s arduous 2020 Australian Open quarterfinal win from seven match points down versus Tennys Sandgren. Like Sandgren, Koepfer was rarely intimidated by Federer’s power. But also like Sandgren, he lacked a few closing shots at the key stages.
So it was that, just as was the case versus Sandgren, Federer drew on poise, precision, variety and nimble defense to extricate himself from many a difficult situation. But Federer’s inability to consolidate leads sapped a great amount of mental and physical energy. In the third set tiebreaker, Federer served at 4-3. Early in the rally, he slashed a forehand wide. But then, Koepfer serving at 4-5, Federer scurried around the court well enough to extract an error and finished the set a point later.
Even a Koepfer wobble early in the fourth set did little for Federer. Serving at 1-all, 30-40, Koepfer struck a backhand down-the-line approach shot that was called wide. Upset by the call, Koepfer walked across the court to inspect the mark. Distraught that it was not overturned, Koepfer spit on the court and was assessed a point penalty.
But serving at 2-1, 40-15, Federer committed a slew of unforced errors. There was a drop in Federer’s energy at this point, perhaps a pragmatic awareness that it was best to focus on holding serve and prepare for the likely tiebreaker; heck, as if this were a match at his beloved Wimbledon.
Surely that scenario seemed likely when Koepfer served at 5-all, 15-love and drove a fierce approach deep to Federer’s backhand that elicited a lob. It went down the line, probably headed wide. But Koepfer opted to play it. Nearly as worse, instead of directing it powerfully angled along the leg of the hypotenuse, into the open court, Koepfer smashed it straight back at Federer, who soon enough won the point – and then rattled off the next six to go up 6-5, 40-love. On Federer’s second match point, Koepfer lined a backhand into the net.
Said Koepfer, “Yeah, it was just a match that I lost a few points here or there, but, yeah, I mean, and in the end it was probably nerves a little bit. Yeah, it is what it is.”
