Speaking to the crowd on court after the contest, she said: "It was incredible, it's been over a year, and a kid later, and I get to go home to her now, so I'm excited about that, but thank you so much for supporting me".
The 36-year-old contested her first competitive match of the year last month, combining with big sister Venus in doubles in team competition the Fed Cup against the Netherlands.
Yulia Putintseva will have her second match at the tournament in Indian Wells tonight, at 1.00 a.m. Astana time.
"I think she's smart to take her time and not to play Australia", ESPN analyst and 18-time Grand Slam singles champion Chris Evert said last week.
"Thursday, the day I play my very first match, marks International Women's Day", she explained. So, that's great! But I'm never a day without Olympia. Williams later revealed she was pregnant during that tournament.
"It's probably been the most fun of my life", she said. "But it doesn't matter, I'm just out here on this journey and doing the best I can".
Tiger Woods Hits Ridiculous Escape Shot At Valspar Championship

Mark Cuban Denies 2011 Allegation of Sexual Assault

Pentagon 'cautiously optimistic' about talks between North, South Korea
However, the state-run media did not mention the issue of denuclearization or dialogue between the United States and North Korea. Later this week, the delegation is scheduled to travel to the U.S.to brief officials on the outcome of the North-South talks.
The first serve continued to be Williams' weapon, throwing her opponent off with a 100mph ace to go 40-0 in the second game. I don't even know how even won the match, and I said I literally can't play the final, but I need a TUE to take a decongestant.
"Serena, this was a while ago but I haven't had an occasion to ask you before", one intrepid hack struck up.
And while Azarenka announced after the win that she was planning on playing in Miami later this month, her long-term future on the tour is still in doubt.
"My focus was just to be out there and enjoy myself, and not to put too much pressure - but of course I've done that in the match, and I wanted to push myself", Azarenka elaborated.
If Serena beats Bertens and her sister Venus beats Sorana Cirstea on Saturday, we may see an early matchup between the two.
Williams has previously shown a reluctance to address the leak and in 2016 even abruptly walking out of an interview with a French broadcaster, when the line of questioning was steered to her TUE usage.
Azarenka says she shares a deeper connection with Williams now that goes beyond their sport. "They will be her three main goals for 2018". "I got to meet her little baby when he was so young and she's been working so hard too".
