The first order of business was Krajicek's first round match against Jana Cepelova, and she served up a winner, dropping a whopping 11 aces to defeat the recent Charleston finalist, 6-3, 4-6, 6-1.
And then the big moment - the icing on the cake of a perfect day. Krajicek's boyfriend, German ATP World Tour player Martin Emmrich, stepped onto the court, went down on one knee, and proposed.
Krajicek said yes.
"It was a huge surprise!" a beaming Krajicek said afterwards. "I mean, we spoke about marriage a couple of times before, but I didn't expect it now. It's very special. I'm really happy and I feel so lucky that he did it like this. We met here one year ago and I think it's such a very special place to do it.
"The first 10 or 15 seconds when he came on the court I thought, 'Okay, it's nice to see him, but this is strange.' But then I saw he had tears in his eyes, and I was like, 'Oh wow,' and I realized what was going to happen! I was so focused on him the whole time I didn't hear anything he was saying!
"I just knew I was for sure going to say yes. That was all I knew in that moment."
How will the happy couple celebrate?
"My parents are here, and his coach is here, so we'll have a nice family celebration," she said. "But we're both still in the tournament - he has a match tomorrow - so we're still focusing on that.
"But I'm sure we'll have enough time to celebrate after!"
Krajicek has been ranked as high as No.30 and has three WTA titles to her name - Tashkent in 2005, Hobart and 's-Hertogenbosch in 2006. Her best run at a Grand Slam came at Wimbledon in 2007, where she made the quarterfinals (falling to eventual finalist - and 2013 champion - Marion Bartoli).
Thank you EVERYONE for all the congratulations and lovely messages!!! What a surreal and magical moment ???
