SPRINGFIELD, N.J. — Before he hit a single practice shot on Baltusrol Golf Club, Jason Day admitted that he felt like his tank was on “E.”

The defending PGA champion said he was “a little under the weather” because of some germs he picked up from his children. Then he was at the emergency room with his wife, Ellie, until about 2 in the morning Wednesday.

She had some kind of allergic reaction, Day said, adding “She got all red.” He called 911. “The paramedics came and and they looked after her, which is great. She’s fine now. We got a little loss of sleep but we’re fine.”

Day met with reporters before his practice round Wednesday, which he said was his first look at Baltusrol. But he was enthusiastic about the information he gathered in a half-hour conversation with the club’s head pro Doug Steffen at the champions dinner Tuesday night.

n Future Olympic schedule changes

Pete Bevacqua, the CEO of the PGA of America, said “Nothing’s off the table” in terms of scheduling the major championship in future Olympic years. The PGA Championship was moved up from its customary August date to accommodate golf’s return to the Summer Games, but there is some concern that the season’s final major is not getting its due in terms of preparation and buildup.

Among the possibilities in future years is to move the event to early spring, before the Masters. “We need to analyze that. We need to cover all options,” Bevacqua said. “We have made no decisions, but yes, it’s absolutely on our radar screen.”

n Bethpage Black and the PGA

The man responsible for the PGA Championship’s course setup was pleased when he visited Bethpage Black last fall to see alterations on the third and 14th greens and new drainage procedures in a number of bunkers. The PGA comes to the Black in 2019.

Kerry Haigh, the managing director of championships for the PGA of America, said he and his staff recognize that the PGA Tour is holding The Barclays on the Black next month. “We’re trying to stay out of their hair,” he said, adding that he will be on site during that tournament to see how the course is playing.

Bethpage superintendent Andy Wilson will be here this week, Haigh said, “Just to see how we might do things differently than he may have seen in the past.” About the Black itself, Haigh said, “It’s a great course. We love it.”
