Former (recently) world no 1 Muguruza participate third time in a row in Singapore. She reached semis two years ago. So she knows the atmosphere and court very well. Ostapenko debuts, and mostly the debutant players the first match is tough. Muguruza also have a real chance to end the year by world number one again, so she cannot waste any chances and be very concentrate.
