Williams has only dropped one set in six Wimbledon matches so far and that, alone, is an impressive feat.
In the past, Williams has often looked to be exorcising personal demons in the latter stages of major tournaments - the power in her strokes matched by the fire in her eyes. And her serve, widely regarded as the greatest in women's tennis, once again packs its daunting punch and placement.
Rightly so. For it was only about 10 months ago she was having a baby and then dealing with a serious health scare that followed.
She's also closing in on her 24th Grand Slam title, which would equal Margaret Court's all-time record. Every day I had to have a new surgery, and it was because all of the blood issues I have, I was really touch and go for a minute ...More news: Chairman Goodlatte: ‘It appears that Lisa Page has something to hide’
"I honestly felt I would have done better in some of the earlier tournaments".
Williams watched Wimbledon from afar previous year when her sister Venus lost to Spain's Garbine Muguruza but, in truth, it feels as if she has never been away after she dropped only one set as she progressed to a 10th Wimbledon final. "That for me is the difference - she's a real warrior - that's to be admired more than anything else".
Nearly decade older than Ostapenko, the 30-year-old's experience and patient waiting game paid rich dividends as Kerber only offered up seven mistakes from her end.
Kerber has already made the semifinal of the Australian Open and the quarterfinal of the French Open this year.
By the end, Ostapenko had far more winners, 30-10, but also far more unforced errors, 36-7.

She would be only the second mother to win the title, only ten months after she gave birth to her daughter, Olympia.
"It doesn't matter if you're a tennis player or a working mum, the balance can be a struggle." said Kim Clijsters, who was the last of three mothers to win a Grand Slam title.
Playing in just the 13th match of her comeback, and facing her first top 50 opponent at Wimbledon, Williams wavered as she got broken while serving for the final at 5-3 on a blistering forehand. I had multiple surgeries and almost didn't make it when I gave birth. "I remember I couldn't even walk to my mail box, so it's definitely not "normal" for me to be in a Wimbledon final". Until the start of this tournament, that was the last match Williams played at Wimbledon.
Serena was pictured with her husband, Reddit founder Alexis Ohanian, at the Royal Wedding in May.
Williams' match against Goerges featured two of the best servers around, and began quite evenly, until 2-all, 30-all.
That Serena, who is among the grittiest and most mentally strong player on tour, has such thoughts and overcomes them, speaks volumes about her determination to compete.

However she has put in just a handful of public appearances since giving birth to Prince Louis in April and has not been seen since she watched her husband play at the polo last month.
