The PGA Championship became the second major championship to announce it is postponing its tournament, as the PGA Tour on Tuesday announced that four more tournaments through May 10 have been canceled.

The PGA Championship, scheduled for May 14-17 at TPC Harding Park in San Francisco, will look for a later date, according to PGA of America CEO Seth Waugh.

“Throughout our evaluation process, we have been committed to following the guidance of public health authorities, and given the coronavirus shelter-in-place order in effect in San Francisco, postponement is the best decision for all involved,” Waugh said in a statement.

Waugh said the PGA of America hopes to reschedule the tournament sometime in the summer, “when it is once again safe and responsible to do so.”

The Masters, the first major of the season scheduled for April 9-12, was postponed indefinitely last week, and it also is looking at possible dates later in the year.

“This is a reflection of a thoughtful process,” Waugh said. “We are and have been working in concert with commissioner Jay Monahan and our partners and friends at the PGA TOUR to find an alternative date that works for all. We are all very hopeful for a great outcome.”

Last week, the PGA Tour canceled the Players Championship as well as this week’s Valspar Championship, the WGC-Dell Technologies Match Play Championship and the Valero Texas Open.
