World champion Carolina Marin had to find a special gear against 2018 India Open champion Beiwen Zhang to help Pune 7 Aces earn their first points in the fourth edition of the Premier Badminton League at the NSCI Dome, Worli yesterday.

Marin, who had lost her first match of the new season against Hyderabad Hunters' PV Sindhu in the tournament opener, was under pressure after her team lost the first two matches of the second tie, having lost all the five matches on Saturday.
