Already paying heed to multiple events including Indian Wells and the Miami Open, the organisers have made the decision not to run the event; for the time being.
Petra Kvitova won last year's edition of the indoor clay tournament defeating Anett Kontaveit in the final 6-3, 7-6; but she will not be back to defend her title at the moment.
“The city of Stuttgart has not specified a specific period for the measures taken today. Therefore, we cannot say at the current time whether; as well as in what form the Grand Prix can take place. The health of everyone involved is a top priority for us; and we in constant communication with the responsible authorities and the WTA”, said a Porsche spokesperson in response to cancelling the event.
