NORTON — She’s not in the neighborhood just yet, but Tropical Storm Hermine is a potential giant pain in the putter for the Deutsche Bank Championship.

With the outer edges of Hermine’s winds and rain expected to move into southern New England later on Sunday, and nasty weather to last through Monday and possibly drag into midweek, DBC officials might have to consider calling the tournament to an end on Sunday, possibly after only 54 holes.

Another possibility, though very slight, would be to require all golfers to complete a double loop of 36 holes on Sunday. The champion then would be crowned, per usual, after 72 holes, with the tournament having been compressed into three days rather than the customary four.

The potential revisions had not escaped the attention of the players during Round 2 on Saturday. Superstar Rory McIlroy, who shot 4 under par in Round 2, noted he would be ready to rip for 36 in one day if so required.

“I could play 36 [Sunday],’’ said McIlroy, in good humor after managing only par on Friday. “Good prep for the Ryder Cup, I guess. I’ve played a couple of 36s there. I don’t mind it. I am definitely one of the guys who doesn’t mind going 36.’’

Overall, McIlroy would prefer double duty Sunday versus, say, the option of having the tournament clipped at 54 holes.

“I wouldn’t like it . . . because I’m five or six shots out of the lead and that’s tough to make up over 18 holes,’’ he said. “But to make it up over 36 I might be more confident I would be able do it.’’

In 2012, Hurricane Irene forced the Barclays Championship in New Jersey to be made official after only 54 holes. Irene ripped into New Jersey and then trekked north through Vermont, causing extensive damage throughout the Green Mountain State.

One key factor that could influence the decision for PGA Tour officials: The BMW Championship is scheduled to begin Thursday at Crooked Stick in Carmel, Ind. Even with Monday’s scheduled finale here, players already were in a hurry-up mind-set because the pro-am, a traditional piece of every tourney, is scheduled for Wednesday at Crooked Stick.

It would be all but impossible to push the DBC final to Tuesday (even if weather permitted), then have players at Crooked Stick for the pro-am on Wednesday, then start tournament play there the next day.

Frosty score

World No. 1 Jason Day, much like Phil Mickelson on Friday, went all Everyman when he posted a snowman 8 on the fifth hole, one of his recovery shots from the woods making a short run down a cartpath that only a true weekend hacker can fully appreciate.

Mickelson put up his 8 on No. 6 in Round 1, his second shot landing in the weeds at the edge of the water hazard. Lefty bravely took two hefty hacks to try to mash his way out, but neither budged the ball. He eventually picked up, dropped, and finished with an 8.

After going 4 over on Friday, Mickelson was 1 over in Round 2, and finished well below the cut line (141) at 75-72—147. Day, at 1 under after two days, just made the cut.

Risky view

If the winds arrive as expected and the championship round is played Monday, it’s a good bet NBC will have to abandon its bird’s-eye camera view of the 18th hole.

John Boeddeker is the veteran cameraman who works that position for NBC, a crane providing his perch 120 feet above the green. Boeddeker delivers some wonderful looks from up there, but if winds start to whip above 20 miles an hour, the network will be forced to keep its visual game on the ground.

Forecasts also have warned against toppling trees, some of which already have been under stress after this summer’s extreme drought. TPC Boston’s 300-plus acres contain many towering hardwoods and pines. The risk of some of them coming down also will have to factor into the Tour officials’ thoughts on whether to play Monday.

A better feel

McIlroy felt his improved play, four strokes better than Friday, was in part due to an adjustment in his putting grip, what he referred to as a “little bit of a tweak.’’ Not to get too technical, he said, but “I tried to get a little bit more into my fingers and just get a bit more feel into it.’’
