It's been a good day so far for the Brits.
Harriet Dartended her 19-month wait for a Grand Slam main-draw singles win, beating American Peyton Stearns 3-6 6-3 6-2.

Harry Wendelken will be hoping to join them in round two - he's currently in action against Italy's Luciano Darderi, leading 5-3 in the second set after losing the first.

Martin Landaluce holds to 30. The pressure is back on Jacob Fearnley. Can he serve out the match at the second time of asking?

A pause is proceedings as the court gets a wipe down. Excellent technique from the ball kid doing the tramlines - towel held to tension between two hands and one foot, scooching along.
Deserved applause from the crowd (though I suspect it's more to do with the impending resumption of play than in appreciation of thorough court care).
*Landaluce 6-4 2-6 6-4 5-7 2-5 Fearnley
Martin Landaluce lets out a shout as Jacob Fearnley fires a shot long.
He's pulled one of the breaks back but will still have to serve to stay in the match. He's only held once in his past six service games.
Make a note of those two match points for Fearnley.

Back to deuce we go.

Oooh just out.
Landaluce 6-4 2-6 6-4 5-7 1-5 Fearnley*
Jacob Fearnley will NOT want to see that point again. He air-shots a smash and has to dash back to retrieve the ball and puts his next stroke into the net.
But, he's still got one match point!

Now, who saw this coming with Jacob Fearnley trailing 5-2 in the fourth set?

Martin Landaluce saves the first break point with a pinpoint wide serve.
Nothing doing on the second, however. He hits another wide serve but this time Jacob Fearnley gets it back into play. Such is the Spaniard's luck, his forehand clips the net cord and pings back onto his side of the court.

Three break points for a 5-1 lead in the fifth set.

It's like Martin Landaluce is playing against a wall. Jacob Fearnley just keeps battering balls back at him, putting him on the back foot with his depth of returning or waiting for the inevitable error.
Speak of the devil... two forehand unforced errors. 0-30.
*Landaluce 6-4 2-6 6-4 5-7 1-4 Fearnley
Jacob Fearnley's forehand technique is quite curious, leaning far back as he whips through the ball, but it's working.
Two forehand winners, two errors created by booming strokes off that wing. Hold to love.
He's two games away from joining Toby Samuel, Katie Boulter, and Harriet Dart in the second round.
