That's always been a bit of an Achilles heel for Heather Watson, it's not a massive serve and her second serve is also very attackable. Her first serve in that game was around 74mph and that is quite slow.

Ouch. After the elation of securing that early break, which brought the buzz right back to Centre Court, a painful double fault and another miss have brought Heather Watson crashing back down to earth.

Niemeier quickly starts to find her shots again and builds up the pressure, racing to 30-0 on Watson's serve before the Brit flips a forehand perfectly to reduce that gap.

Niemeier gets two break points but only needs one as Watson makes her 12th unforced error of the day.

It was pretty much a faultless set for Jule Niemeier - I thought she might be more nervous walking out on this court for the first time with most of the British public getting behind Heather Watson early on - I thought that may have unsettled her, but no it hasn't.

While we take a breather during the change of ends, watch Sue Barker receive a standing ovation from the Centre Court crowd after John McEnroe pays an emotional tribute to the BBC presenter, who is stepping down after covering Wimbledon for 30 years.

With the exception of that double fault, Jule Niemeier has made no mistakes in this first set. She's dominated.

Heather Watson, meanwhile, is feeling the pressure and looking a bit frustrated. She slams the ball into the net in anger after missing an easy point at 30-15 down.

Successive breaks of serve for Jule Niemeier have dampened the mood somewhat on Centre Court.

There are shouts of encouragement for Heather Watson as she steps back out following the change of ends, but the first set looks to have been moved swiftly out of reach.

A couple of slip-ups with Watson's groundstrokes followed by a measured lob from Niemeier brings up another two break points for the 22-year-old.

She's unable to convert the first after much better play from Watson, but gets the second as the Brit puts too much on a forehand.

Niemeier will serve for the first set.

Britain's Joe Salisbury and American Rajeev Ram are aiming to win their third Grand Slam title together after clinching the men's doubles championships at the 2020 Australian Open and the 2021 US Open.

They are the top seeds in this year's competition and are next up on Court Three as they take on the 16th-seeded pairing of Rafael Matos of Brazil and David Vega Hernandez of Spain.

There was already an excited atmosphere on Centre Court following the centenary celebrations, but that wonderful point preceding Niemeier's second hold had the crowd out of their feet long before the action had finished.

It looked as though Watson had caught her opponent out as she produced that lob to the back of the court, but it was the German who ended with her arms raised as she draws the killer blow. Superb.

A first ace of the day for Jule Niemeier on her first serve of the game, before a Watson backhand fails to clear the net.

The rally on the third point is extraordinary, and they're both left smiling as the crowd shows their appreciation. Niemeier won the point with a forehand just out of Watson's reach, but it could have quite easily gone the Brit's way. Make sure you watch that on the highlights later.

A second successive love hold for Niemeier.

It is going to be important for Heather Watson to serve well, she's up against a big server. She needs to be strong on her first serve and be brave on her second too, look to mix it up.

Heather Watson bags the first ace of the day to move to 30-15 after conceding the first point of her serve.

She easily meets an attempted Niemeier lob at the net and from there gets the hold as the German fires a forehand wide.
