    Paolini 5-4 Andreescu*

    Jamsine Paolini is wearing a wry smile after Hawkeye backs up the line judge's call that her ace clipped the line.

    She closes out the game and retakes the lead late in the first. Bianca Andreescu will serve to stay in the set.

    An ace down the T from Frances Tiafoe to secure his own hold to love.

    Both players quickly into their work on serve.

    Frances Tiafoe is still wearing that support on his knee.

    The American 29th seed retired early from his second round match at Queen's last month after a nasty fall on the grass.

    Carlos Alcaraz holds to love. Simple as you like for the defending champion to get things started.

    Frances Tiafoe is a big time player who loves the big stage. So, if things are clicking, if it's the real Tiafoe we see today, there's absolutely no doubt that he can hurt Carlos Alcaraz.

    Jasmine Paolini is a different player on grass this year.

    You have to unlock something because the surface is so unique.

    Away we go.

    Both players just feeling their way into the match but Carlos Alcaraz takes the first point on serve as Frances Tiafoe's forehand goes long.

    The sound of the ball being whacked off the racquets is reverberating around the roof-covered Court One. It is first-strike, athletic tennis from both Jasmine Paolini and Bianca Andreescu.

    Carlos Alcaraz and Frances Tiafoe offer very different vibes as they take to the court.

    The defending champion is bouncing off the walls, running on the spot and practising his swing as he talks to the umpire.

    Tiafoe takes his time taking off his headphones before strolling over, shoulders back, looking relaxed.

    Paula Badosa just ripped a forehand winner right down the line.

    “Woooosh” is the sound from her team to my right.

    Top class hitting.

    Plenty of familiar sporting faces at Wimbledon today.

    Kansas City Chiefs quarter-back Patrick Mahomes is in town, as is former England cricketer Stuart Broad and his partner, Radio 1 DJ Mollie King.

    Wales international rugby player Dan Biggar has also arrived at SW19.

    This is exciting tennis because they both go after each shot. They just unload.

    Bianca Andreescu is very alert to move forward at every opportunity, that's one of the things I love about her game.

    It's really important to mix up your serves at least once in a while.

    A good number of Paula Badosa supporters are here today.

    Shouts of “come on, Paula” and “vamos” can be heard just to my left.

    This could turn out to be a cracker.

    Here come the players, welcomed by loud cheers from the crowd on Centre Court.

    Based on previous meetings between these two, this should be a very fun match.

    Both players are hitting the ball really hard. Bianca Andreescu and Jasmine Paolini's inside-out forehands are going to be the key.

    Whoever can get that strike first is winning the point. Both are looking good and confident.

    It’s Paula Badosa who has made the best start on court three as she earns an early break.

    The Spaniard has started this match with real intent and has been unleashing some tremendous shots already.

    Daria Kasatkina, on the other hand, is looking a little annoyed with herself.

    The "come on!" shouted by Bianca Andreescu when she served an ace on the second break point had as much force as the serve. And there's another yell as she outlasts Jamine Paolini to hold. This is shaping up to be a cracker.
