It's a legit quote by him from a now deleted forum post on his website:

“The recent incident at the tennis match has caused a disproportionate online uproar. It’s all about the famous hat, of course. Yes, I took it. Yes, I did it quickly. But as I’ve always said, life is first come, first served,” he claimed.

“In the end, chin up, hats off, less venom, more sportsmanship.”

The douche still has the hat and that's unacceptable.
If I were Majchrzak I would clarify he did certainly not 'pass his hat in his direction' and that he wants it back.
Otherwise he can file a police report for theft.
