That’s all for tonight. Thanks as always for following along with us and be sure to check back shortly for our full report off Tuesday night’s action.

Fourth set: *Alcaraz 6-2, 4-6, 6-3, 5-1 Tu (*denotes next server)

Tu falls behind love-30, then 15-40, and it’s two match points for Alcaraz. The Spaniard squanders the first with a missed volley, then Tu saves the second with an 80mph second serve that clips the net before caroming backward. From there Tu grinds out the hold, getting on the board in this fourth set and earning a hearty round of applause from the Ashe crowd while he grins from ear to ear. They’re not saying boo, they’re saying Tuuuuu!

Fourth set: *Alcaraz 6-2, 4-6, 6-3, 5-0 Tu* (*denotes next server)

Alcaraz wastes no time backing up the break, going 119mph ace, forehand winner, forehand winner, 119mph ace to hold at love. Tu will serve to stay in the tournament after the changeover. Meanwhile, Kenin is serving for the match at 5-4 in the third against Raducanu.

Alcaraz breaks in fourth game of fourth set!

Tu double-faults again to go behind love-30 on his serve. That’s 16 of the last 17 points for Alcaraz. The Spaniard then misfires on a couple of shots for 30-all, then just misses on a cross-court backhand. That’s when Tu makes three straight unforced errors, all off the backhand side, to gift Alcaraz another break. He grimaces as if the cramps are about to start, if they haven’t already.

Fourth set: Alcaraz 6-2, 4-6, 6-3, 1-0 Tu* (*denotes next server)

After Tu took a lengthy bathroom break between sets to recharge, Alcaraz breezes through a love hold. We’re not loving what we see from the Aussie right now, fitness-wise.

Tu opens with a 116mph ace before winning a remarkable 19-shot rally with a forehand winner that brings the crowd to its feet. But the glory is short-lived. Alcaraz responds with a pair of quick winners for 30-all, before a visibly gassed Tu, breathing quite hard, makes a clear fatigue error for 30-40. Another break-point chance for Alcaraz ... and this time he converts, ripping a sharply angled forehand from the baseline that Tu can’t handle!

Gut-check moment for Tu, who goes behind love-30 before a backhand unforced error from the baseline for 30-40. A break-point chance for Alcaraz, but he fritters it away with a misfired backhand for deuce. A few uncomfortable moments later, Tu escapes with the hold.

A note from reader Laura asks: “Have we finally given up on [Emma] Raducanu?” considering we’ve yet to mention her ongoing first-round match on Grandstand in this space. I do now see the 2021 US Open women’s champion has just forced a third and deciding set in her tangle with Sofia Kenin, the 2020 Australian Open winner. Since your faithful narrator is tippy-tapping away from the press seats on Ashe, a fuller analysis must wait for now … but we’ll keep you posted.

Third set: Alcaraz 6-2, 4-6, 2-2 Tu* (*denotes next server)

Easy hold for Alcaraz, who has won eight of the last 10 points on his racket. Surely he looks like the fitter man on court at the moment.

Third set: Alcaraz 6-2, 4-6, 1-1 Tu* (*denotes next server)

Alcaraz flies to a straightforward hold of serve, capping it with a 125mph ace down the middle. After that nightmarish service game to end the second (including three double faults), it’s much welcome.

Second set: Alcaraz 6-2, 4-4 Tu* (*denotes next server)

Well, this just got interesting. Just when it looked like Alcaraz was poised to run away with the second set and for all intents and purposes the match, the 2022 US Open champion goes behind love-15, then 15-40 after Tu passes him with a stunning backhand winner. That’s two break-point chances for Tu. And he only needs the one! Another scattershot forehand by Alcaraz gifts Tu the break, the Adelaide man’s first of the evening, and we’re back on level terms in the second stanza at four games apiece!

Second set: *Alcaraz 6-2, 4-3 Tu (*denotes next server)

Alcaraz keeps on applying pressure and ultimately you crack. Tu goes behind love-15 after an Alcaraz winner, then 15-40 and double break point.

Now it’s Tu’s turn to feel the heat. The Aussie goes behind love-30 after a blistering Alcaraz backhand winner at the net. Tu wins three quick points, including a gorgeous backhand volley winner, for 40-30. But a couple of misfired forehands leave Tu facing his first break point of the set. And he saves it! Another serve-and-volley, putting it away with a forehand into the open court. Deuce. But another unforced error off Tu’s forehand gives Alcaraz a second break-point chance. This one he squanders, spraying a forehand wide. Moments later Alcaraz has a third look at a break and Tu saves this one also before escaping with the hold ... but not before trying an underarm first serve on game point that failed miserably. It draws laughs from the crowd and prompts Tu to apologize to Alcaraz during the changeover.

Second set: Alcaraz 6-2, 2-2 Tu* (*denotes next server)

Alcaraz goes behind love-30 on his serve thanks to another unforced error followed by a double fault. The Spaniard is getting a wee bit casual: five unforced in the last two games after only three in the first 10. But he wins four quick points in succession to hold and remain on serve.

Second set: *Alcaraz 6-2, 1-2 Tu (*denotes next server)

First set: *Alcaraz 5-2 Tu (*denotes next server)

Tu falls behind love-30 on his serve and Alcaraz is two points from the set. Alcaraz then donates an unforced error (only his second of the night) and Tu follows with a forehand volley winner after a nine-shot rally that prompts roars from the crowd. Tu then hits a forehand winner into the open court following a 116mph serve for game point, before threading a 95mph second-serve service winner down the middle for the gutsy hold. Alcaraz to serve for the opening set after the change of ends.

First set: Alcaraz 5-1 Tu* (*denotes next server)

Love hold for Alcaraz. and another drama-free service game for Alcaraz, who’s won 12 of 14 points on his racket so far. Now Tu will serve to stay in the opening set.

First set: *Alcaraz 4-1 Tu (*denotes next server)

Tu is on the board at last but not without a fight! Alcaraz, moving about the court with ease and showing no sign of the twisted ankle he suffered during training on Saturday, makes him work for every point. But he’s able to hold serve after a lob by Alcaraz misses the mark and the Ashe crowd offers up a hearty round of applause that brings a smile to Tu’s face.

First set: Alcaraz 4-0 Tu* (*denotes next server)

Alcaraz consolidates again, pounding a 110mph service winner, a 124mph ace out wide and capping it with a forehand winner from inside the baseline. Already seven winners for the Spaniard with just the one unforced error.

It’s not getting any easier for Tu on his serve. He quickly goes triple break point down, mixing in his first double fault of the night. He’s fends off a pair of them with a couple of strong serves, but another misfired forehand from the baseline gives Alcaraz a double-break lead after 10 minutes.

First set: Alcaraz 2-0 Tu* (*denotes next server)

Tu gets on the board with style, getting the better of Alcaraz over a 10-shot exchange before passing the Spaniard with a backhand winner. But Alcaraz responds with a 116mph ace down the middle before rattling off three quick points for the stress-free hold.

Alcaraz breaks in first game of first set!

First set: *Alcaraz 1-0 Tu (*denotes next server)

A shaky start for the US Open debutant, who’s quickly broken at love to start the match. Alcaraz hits a sizzling forehand winner early in the point for 40-love before Tu donates the game with a forehand unforced error at the net.

Some backstory for the Adelaide man Li Tu. He made his ITF debut in 2011. He retired in 2014 and was out of the sport for six years, earning his degree and founding a coaching academy during his time away. Since returning in 2021, he’s won nine ITF titles and one more at the Challenger level. He exuded confidence during his pre-match interview in the tunnel, but make no mistake: this one is as David v Goliath as it gets. Alcaraz has won four of the last seven majors staged, winning 42 of 45 matched over that span.

The players are on court and going through their warm-ups. Ashe is about two-thirds empty at the moment but the teeming queues outside by the fountains suggest it will be filling up quickly. We should be under way in a couple of minutes.

Before we get started ... Dan Evans has just toppled Karen Khachanov in the longest match in US Open history. The 34-year-old Briton rallied from 0-4 down in the fifth set to win 6-7 (6), 7-6 (2), 7-6 (2), 4-6, 6-4 after 5hr 35min (!). That eclipses the previous mark held by the famous 1992 semi-final between Stefan Edberg and Michael Chang, which took 5hr 27min to complete.

Bryan will be here shortly. In the meantime here’s a look at what’s happening as the day session gives way to night in Queens.
