At the time of going to press, the Banga Beats were leading two-nil with Yun Hu also winning over Wei Feng Chong of Awadhe Warriors 21-11, 21-20.
The left-handed Marin, who was a quarter-finalist at the World Championships where she lost to eventual champion Ratchanok Intanon, proved too good for India’s Sindhu who herself was a bronze medallist at the event.
At one point in the first game, Marin took a 7-4 lead against the Hyderabadi girl and never quite looked back from there.
In the second game too, Marin was in the lead from the start before eventually clinching the game, and the match.
Earlier, World No 8 Yun Hu had overcome the Warriors’ Wei Feng Chong in straight games.
Chong, the World No 13, tried his best but was no match for the might of Hong Kong’s Hu.
