First was the NBA. Then came MLS and the NHL. Then the NCAA Tournament and MLB. Those major sports organizations ceased operation on Wednesday and Thursday.

Then, on Friday morning, the PGA Tour announced it was suspending play for the next month.

And now the Masters.

After Masters organizers were radio silent the previous two days as the rest of the sports world shut down, venerable Augusta National Golf Club, which walks to its own beat, announced Friday the tournament, which was to begin the week of April 6, is being postponed.

“Ultimately, the health and well-being of everyone associated with these events and the citizens of the Augusta community led us to this decision,” Fred Ridley, chairman of Augusta National, said in a statement. “We hope this postponement puts us in the best position to safely host the Masters Tournament and our amateur events at some later date.”

It’s unclear when the event will be played and whether the Augusta National Women’s Amateur and Drive, Chip & Putt events will also be part of the rescheduling. The Masters, which dates to 1934, has never been played outside of March or April.

Tiger Woods is the defending champion, having won his fifth green jacket and 15th career major championship last April.

The Masters became the sixth event on the PGA Tour schedule that will not be played in its current spot on the calendar, following the cancellation of the remainder of The Players Championship, next week’s Valspar Championship in Palm Harbor, Fla., the WGC-Dell Match Play Championship in Austin, Texas, the opposite-field event in the Dominican Republic, and the Valero Texas Open in San Antonio.

“I think they’re doing the right thing, and I look forward to hopefully playing the Masters later this year,’’ Justin Thomas said Friday. “I felt like there was no chance we were going to play the Masters. Obviously, I wanted to, but I didn’t think we were going to, to be perfectly honest.

“But then again, you have days at Augusta where it looks like there’s going to be a tornado and it’s perfectly sunny. Some freaky things seem to happen around there. So, I didn’t know what was going to happen, but it’s definitely for the best decision and what needed to be done.’’

The PGA Tour sent texts to the players competing in The Players Championship shortly before 10 p.m. Thursday to alert them that the tournament was being canceled — despite the fact that earlier in the day Tour commissioner Jay Monahan said the tournament would play on, but without spectators.

At the time, some players were glued to their mobile phones breathlessly searching for the latest news and some already were asleep, resting for their early tee times Friday.

Monahan, in a press conference Friday, said among the things that influenced him to change course and cancel the tournament entirely were player input and the fact Walt Disney World and Universal Studios were closing down.

On Friday, with many of the players at TPC Sawgrass to clean out their lockers, the reaction was universal in support of the Tour canceling The Players, which paid out half of its $15 million purse to be split up equally among the players who competed, paying them about $52,000 each.

“I didn’t talk to Jay, [but] I was hoping he made the decision [to cancel],’’ reigning U.S. Open champion Gary Woodland said Friday. “If I would have been asked, I would have told him I didn’t think we should be playing.

“We had to do it. It would have looked horrible if we showed up and played [Friday] with every other sports league not playing. It probably would have been insensitive, so I’m glad Jay made the decision that he did. It’s best for us. It’s best for the fans and our families. Hopefully, the world comes together and we get over this.

“This is obviously a very serious deal, and I think it’s only going to get worse right now, so it’s best for us not to be playing golf.’’

Rory McIlroy called it “the right decision’’ not to play Friday and until further notice.

Bernd Wiesberger, who’s from Austria and plays most of his golf on the European Tour, was relieved by the Tour’s decision to cancel and the Masters decision to postpone because he was facing the European travel ban that went onto effect Friday.

“Obviously, everyone would love to see some golf, but in the bigger picture I’m in constant contact with family and relatives in Europe and it’s pretty bad there,’’ he said. “I’m looking forward to going back home and being with them and help out over there.

“It’s unprecedented times. We all need to kind of stick together and do the right thing for everyone, for the elderly, to not have anyone affected that doesn’t need to be, and therefore I think it’s good we’re packing up and kind of going home and try to have as minimal social contact as possible and try not to spread it any further.’’
