Tai Tzu-ying
Marín won the first title of the year, the Thailand Open Super 1000 event, by beating World no. 1 Tai Tzu-ying in two comfortable games. She didn't lose any game in the whole tournament. Continuing her scintillating form, she won the second edition of Thailand Open, the Toyota Thailand Open, also a super 1000 event by beating Tai Tzu-ying yet again. In contesting her first-ever World Tour Finals final, she lost to same rival Tai Tzu-ying in three games after failing to capitalize her lead in the final game. She won her first world tour title in Switzerland by beating reigning World champion P. V. Sindhu with a very dominating display, winning 21–12, 21–5. Marín has planned to compete at the All England Open. But, she pulled out of the competition, due to an injury she suffered in the first round of the Swiss Open two weeks ago.
