Elena Rybakina is looking quite unstoppable when she gets on top of the baseline. Caty McNally keeps trying to neutralise her, taking pace off the ball, but Rybakina manipulates her position until the avenue opens up for a down-the-line forehand. 30-all.

After hunting down a drop shot on her forehand, she races across the net for a backhand volley winner. Uh oh.

One thing we have to remember is Jakub Mensik won his first-round match in the super tie-breaker, the match was four and a half hours long, so Grigor Dimitrov has that in his favour.

There is a chance the Czech might get tired, although he is 20 years old and one of the fittest players I've seen. It might be the case that he is a quarter of a step slower, though.

Nine break points and counting now for Jakub Mensik, who just can't get over the line in a Grigor Dimitrov service game.

Dimitrov is finding a way when it really matters.

Caty McNally double-faulted to hand Elena Rybakina the break in her previous service game.

She's started this one with a double fault...

This is Tiafoe's 39th consecutive Grand Slam appearance. That is the longest active streak.

He has played plenty of tennis in 2026 with 30 wins so far this season. Eight of those have come on grass.

Lovely stuff from Frances Tiafoe as he draws Jan Choinski to the net and then lobs the the 6ft 5in Briton for 15-15.

That's as good as it gets for the American, though, as Choinski gets the hold to 15.

Jan Choinski gets to 30-30 and to put a little bit of pressure on Frances Tiafoe but a couple of loose returns means the game slips away.

Tiafoe consolidates that earlier break.

Elena Rybakina eases through a hold to love. The second seed's serve is starting to click.

A bit of a damp squib to finish the game. Double fault.

Elena Rybakina is really attacking Caty McNally's serve, standing on the baseline even for first serves. It pays off - another cross-court missile.

Jakub Mensik faces a break point for the first time in the match, but finds a big serve at the right time to prevent Grigor Dimitrov taking a real stranglehold on this second-round match.

Three break points saved by Caty McNally in this game. The American is still shaking a celebratory fist as she winds up to serve.

Ah, erm, yes... Caty McNally goes for a serve and volley but plants her backhand in the net.

Choinski's first serve percentage is struggling, sat at 50 percent. He needs to try and land one.

You can tell Caty McNally is a strong doubles player. Very confident at the net. She reads an attempted backhand pass and pings a short backhand volley winner.

Slightly challenging conditions out on Centre Court with one half of the baseline at the Royal Box end in bright sunshine and the rest of the court in shade.

Elena Rybakina gets on top of a couple of serves to lead 0-30. And then a bruiser of a cross-court forehand return, angled and quite short, for 15-40.

Jan Choinski starts positively to lead 30-0 but he's been guilty of not moving his feet on a few occasions and he leaves them planted as his scooped forehand drops short.

After sending Frances Tiafoe wide, Choinski seems to have too much time to hit a winner into an open court and fires long.

But a wild mis-hit from Tiafoe on the next point allows Choinski to seal the hold.

Two break points saved. A hard-fought hold for Elena Rybakina.

She secures it with a deep forehand down the line after pegging Caty McNally back in the opposite corner.

Frances Tiafoe drops his fifth double fault of the match to hand Jan Choinski a 30-0 lead.

Tiafoe forces his way back into the game as they reach deuce and then he profits from a long Choinski forehand for advantage.

Choinski goes long again and what initially looked like a strong position has completely crumbled away.

Elena Rybakina just can't find her rhythm.
