I can understand her frustration, though. You're powerless if the umpire is not strict enough on dirty tactics like time-wasting.
Marin not happy that Umpire didn't give Sun Yu a red card for time wasting. Chen jin said to her, when she was still grumbling after the match, that she has a problem, to which Marin said she didn't and "you know". Through out the match Marin was serving intentionally early when Sun Yu wasn't ready to receive to demonstrate her annoyance.
with new rules about not flicking off sweat she very well deserves a towel down after 7 points played, it's not time wasting.
Can't really make out what she was saying, something like,'... and you know what she's doing'. Referring to her delaying tatctics, i.e. not getting read for which SY was yellow-carded or her supposed injury fear ? Anyway,Marin is not doing herself any favours behaving like that when there's the umpire and tournament referee to turn to instead of the opponent's coach who has no control over anything between the players.
CM shouldn't complain about other players, when she uses verbal celebrations to intimidate her opponents, sometimes shouting at their faces.
By her actions, Marin also shows little respect for the umpire who've already warned Sun Yu and even yellow-carded her for the service delays. After the yellow card , Sun Yu is risking a red card, that would've have affected Sun Yu's mind or nerves somewhat.
Maybe Hu Yun wasn't expecting to come here, in that case, why not give it to his compatriot, Vincent Wong.
I don't think Hu Yun really cares too much about this match against JOJ lol. Would probably try harder against MZ and THW if he isn't injured that is.
