Under Side Spin( side spin + down(backspin) ) or Top Spin Side Spin or Ordinary Side spin
Thanks for your question.
Where abouts in the video do you specifically mean? It’s just because Dimitrij is using a wide range of spins in this video clip. He is disguising doing a lot of backspin + Sidespin that looks topspin and vice versa. If you could let me know which time in the video I can let you know what spin is on the ball.
what kind of service does it use, backspin + side and top spin + side and everything? Or still any?
