Ratajski spoke afterwards and said he was really happy to win the title in the end.
He was behind for a lot of the final but got back on level terms and he added that when it got to 7-7 he said to himself he must win it.
"I'm very happy," said Ratajski. "It was very tight and it was really, really hard.
"I played my semi-final against Danny Noppert and I had never beaten him, but today I played almost a 104 average and it was superb.
"In the final with Dimitri, I've also lost with him many times, and I thought about it. When I was 7-7, I said to myself that I must win. It's a very important result for me."
