The United States PGA Championship today became golf's latest major championship to feel the wrath of the Covid-19 virus.

The PGA of America today announced its flagship event, scheduled for TPC Harding Park in San Francisco from May 14-17, had been postponed.

It joins the Masters and, on the LPGA side, the ANA Inspiration as majors all put on hold until the corona virus threat sweeping the world subsides.

"Throughout our evaluation process, we have been committed to following the guidance of public health authorities and ... postponement is the best decision for all involved,” PGA of America chief executive Seth Waugh said.

"We are and have been working (with) the (US) PGA Tour to find an alternative date that works for all. We are all very hopeful for a great outcome.

"(We) look forward to hopefully bringing the 2020 PGA Championship to TPC Harding Park at a date this summer when it is once again safe and responsible to do so."

Two weeks ago the US Tour cancelled four lead-up events to the Masters. Today it added to the cancellation pile by axing the four events following the scheduled Augusta date.

The RBC Heritage (April 16-19); Zurich Classic of New Orleans (April 23-26); Wells Fargo Championship (April 30-May 3); and Byron Nelson Championship (May 7-10) all will not be played in 2020.

The LPGA recently announced the postponement of its first three American-based events for the season, up to and including the ANA Inspiration.

The European Tour today added the Andalucia Masters (April 30-May 3) to its postponed list, joining events in China, Malaysia, India and Kenya in that category.
