Serena Williams is the new tennis queen of Auckland – and this ASB Classic triumph might be one of the most special of her career.
And she announced - minutes after her first victory in three years - that she was donating her prize money, almost $100,000, to the Australian bushfires relief.
The American legend has won a staggering 72 titles across her glittering career, encompassing 23 grand slam tournaments, five WTA finals trophies and numerous other victories at big events.
But her win on the Stanley Street courts on Sunday was the first time she has claimed a tournament since her daughter Olympia was born in October 2017, ending a streak of five finals defeats as a mother.
It's special, and that raw emotion was evident throughout the contest, especially early in the first set when Williams was battling a few demons and struggling to find her range.
However her class and experience told in the end, as she prevailed 6-3 6-4 in 96 minutes.
It completes a magical week for Williams, and the tournament. She revealed last Sunday that she felt obliged to come back to Auckland, as her unhappy time here in 2017 was "where it all began", as she unknowingly played the first tournament since falling pregnant.
If Williams wanted redemption here, she got it in a big way. She has been popular around the event –creating a buzz wherever she went, and poured her heart and soul into her endeavours on the court, in both singles and doubles.
Williams has improved significantly across the week, but it has rarely been straightforward, aside from the semi-final demolition of Amanda Anisimova. She dropped a set to Christina McHale in the second round, and battled blustery conditions in first two rounds.
But she worked hard, never stopped fighting and at times looked unstoppable.
Williams took a while to get going on Sunday. She dropped her first service game, eschewing two game points, which stretched over five minutes. After Pegula held, the pattern continued, with Williams fending off four break points to avoid a 0-3 deficit, showing her relief with a huge, Lleyton Hewitt style 'C'mon!
Williams was trying to fire herself up, willing the mind to inspire the body, but World No 83 Pegula was equal to everything, impressing with her fearless approach.
Her movement was superb, her shot selection spot on, and unlike the other players this week, the 25-year-old managed to live with the pace that Williams was generating.
But Williams finally enjoyed a convincing hold for 2-3, signalling a subtle shift in momentum, with consecutive breaks.
The crucial moment came at 4-3 in the first set. After missing three, Williams set up her fourth break point with an athletic retrieval of a drop shot. She prevailed in the next rally, with a superb backhand winner down the line, before turning to face the Robinson Stand, arms raised in the air.
Williams looked exhausted from her exertions, but had done enough, and converted her second set point minutes later.
It should have been downhill from there, but Pegula, who won her WTA title in Washington D.C. last year, refused to succumb easily.
She defended four break points in the first game of the second set, but was broken at her next turn from the line.
Williams maintained her advantage, but Pegula defied her inexperience in finals with a gutsy display, particularly serving a 3-5 down, when she faced three championship points and saved them all.
Williams was bringing her full arsenal, from forehands that defied physics to delicate drop shots, but Pegula was equal to the task.
But Williams wasn't going to be denied, and a winner down the line cemented her 73rd title – and first that daughter Olympia has witnessed.
