LAKE BUENA VISTA, Fla. — The race in the Western Conference for two play-in game spots will go down to the wire.

And the difference could be razor close — just about the slimmest possible.

A season like none other in NBA history may get a finish like none other, at least in the West. An analysis by The Associated Press shows there is a scenario where the final difference between teams in the play-in race could be less than 0.001% — yes, less than one thousandth of a per cent.

Memphis, Portland, San Antonio and Phoenix — the still-unbeaten-in-the-bubble, 6-0 at Disney Suns — are the last four teams standing in the race for the last West spot. The margin between the eighth-place Grizzlies and 11th-place Spurs, entering Tuesday, is just one game, and all four clubs have two games remaining.

All four teams play Tuesday. If Memphis and Portland both win, and Phoenix and San Antonio both lose, the race is over and the Grizzlies and Blazers clinch spots.

Otherwise, the race goes to Thursday, when it’ll have to be known who the two clubs are that will be headed to the best-of-two play-in series. The ninth-place finisher will have to beat the eighth-place finisher twice to advance.

That series starts Saturday on ABC. Game 2, if necessary, is Sunday on ESPN. And by then, finally, someone will be able to start preparing for a West first-round series against the top-seeded Los Angeles Lakers.

The super-close scenarios are mind-blowing. Try this: Should Phoenix and San Antonio both win their final two games, it would see the Suns finish ahead of the Spurs by 0.00096 percentage points.

Memphis and Phoenix also could finish with identical records, though then it gets easy — the Grizzlies won the season series and hold the tiebreaker.

A look at the field:

MEMPHIS

Record entering Tuesday: 33-38, 8th in the West

Remaining games: Boston on Tuesday, Milwaukee on Thursday

Outlook: Not only do the Grizzlies control their own destiny, but they catch the bonus of their last two opponents having absolutely nothing at stake. Boston is locked into the No. 3 seed in the East, Milwaukee the No. 1 seed. For Memphis, the math is very simple. If the Grizzlies win one game, they clinch no worse than a play-in spot. Win two, they’ll finish eighth and hold the upper hand in the play-in series. But if they go 0-2, the door opens for others.

PORTLAND

Record entering Tuesday: 33-39, 9th in the West

Remaining games: Dallas on Tuesday, Brooklyn on Thursday

Outlook: Getting Dallas on the second half of the Mavericks' back-to-back Tuesday isn’t the greatest news, especially since the Mavs can still get to the No. 6 seed and Luka Doncic — who didn’t play Monday — sounds as if he could play Tuesday. The Nets are locked into the No. 7 spot in the East, meaning they’ll face defending champion Toronto in the first round. A 2-0 finish would assure Portland a spot; a 1-1 finish means the Blazers would need some help. And Portland could go 0-2 in its final games and still get in, but San Antonio and Phoenix would have to both go 0-2 as well for that to happen.

PHOENIX

Record entering Tuesday: 32-39, 10th in the West

Remaining games: Philadelphia on Tuesday, Dallas on Thursday

Outlook: The Suns are the story of the bubble, 6-0 at Disney so far — but even 8-0 might not guarantee them a spot in the play-in game. They play Philadelphia on Tuesday, a 76ers team that will be without Ben Simmons (knee) and Joel Embiid (ankle). If the Suns go 1-1 in their final two games, Portland would have to go 0-2 to give Phoenix a chance at the play-in. An 0-2 finish would have the Suns going home before the weekend.

SAN ANTONIO

Record entering Tuesday: 31-38, 11th in the West

Remaining games: Houston on Tuesday, Utah on Thursday

Outlook: There is a way for San Antonio to get to the No. 8 seed with a 2-0 finish, and there’s also a way for the Spurs to miss the play-in series entirely — also with a 2-0 finish. Any loss would all but doom the Spurs’ chances; going 1-1 would leave them with a .451 winning percentage. Memphis won’t fall below that (the worst the Grizzlies can do is .452) and Portland and Phoenix would both exceed .451 by simply going 1-1. The Spurs are playing for what would be a 23rd consecutive playoff appearance, something no NBA franchise has ever accomplished.
