The Yankees have the majors’ second-best record, entered Tuesday 30 games over .500 and had a 99.8 percent chance of reaching the postseason (per FanGraphs).

Does that provide perspective or an alibi?

The Yankees moved into a first-place tie on July 1 and had gone 20-17 since, the AL’s fourth-best record. Yet, they lost 10 games in the standings, as Boston has gone 29-6. So, are the Yankees failing compared to the Red Sox or just failing?

Part of the answer is that the Yankees were one of seven teams — the Super Seven — expected to separate from the rest of the rabble this year. Yet, if the season ended Monday, two of the seven — the Nationals and Dodgers — would miss the playoffs. And the Yankees, Astros and Cubs face some peril over the rest of the season.

Bovada (like every forecast model) had those clubs, plus the Indians and Red Sox, as superior to the field, placing their over/unders between 91 1/2 and 96 1/2. The eighth best was 85 1/2 for the Cardinals and Diamondbacks.

The Red Sox, Yankees and Astros are the lone teams exceeding a .600 winning percentage. But six of the majors’ seven best records reside in the AL and just five make the playoffs. The Red Sox, by playing historically, and the Indians, by playing in the miserable AL Central, are locks. Thus, one from among the Yankees, Astros, A’s and Mariners — all on pace for 93 or more wins — will be out.

Meanwhile, in the NL no team led a division by more than two games, and eight clubs were either in a wild-card spot or within 6 1/2 games.

What does this mean for the Super Seven? Here’s my concern level, in order of highest to lowest. (All percentages from Fangraphs through Monday’s games.)

1. Nationals (16.1 percent to win the division, 30.7 to make the playoffs, 2.6 to win the World Series): They are the majors’ biggest disappointment, yet have the kind of talent base that makes you believe if they get their act together, they could win a World Series. Three-quarters into the season, though, no signs exist of a cohesive group capable of playing to its pediree.

Because of that pedigree, they did not give up at the trade deadline, but did jettison two relievers (Shawn Kelley, Brandon Kintzler), namely for attitude reasons, which hurt depth, especially with closer Sean Doolittle, Kelvin Herrera and Ryan Madson on the DL. They lost on walk-off homers Sunday and Monday, and afterward rookie manager Davey Martinez – perhaps over his head for this job – said, “I don’t know what else to do.”

2. Dodgers (64.8/79.3/13.1): After disabling closer Kenley Jansen with an irregular heartbeat with the expectation he will miss at least a month, Los Angeles lost its next four games due to late bullpen collapses. The Dodgers hope the pen injection of starters Kenta Maeda and Ross Stripling helps. Manny Machado’s impact has been minimal. Another new addition, second baseman Brian Dozier, was diagnosed with an abnormal heartbeat. Max Muncy has slowed, and Matt Kemp has plummeted. The Dodgers have the division’s best roster, but have yet to be able to shake the Diamondbacks or Rockies. And even the Giants linger.

3. Cubs (85.5/97.5/10.8):

Jon Lester has the majors’ worst starter ERA (8.01) since July 1. Yu Darvish remains on the DL with persistent questions about his durability and fortitude. New addition Cole Hamels has been a rotation godsend. But the Cubs cannot be sure when and in what condition third baseman Kris Bryant (shoulder) and closer Brandon Morrow (bicep) return. The Brewers loom, and has anyone noticed the Cardinals have been doing a lot of winning under interim manager Mike Shildt and that they finish their season with three against their No. 1 rival at Wrigley?

4. Yankees (4.8/99.8/9.2): The Yanks were built to overcome rotation-depth concerns because Luis Severino is elite and the bullpen and lineup are deep. But Severino is trapped in a 2016 time warp. Since Zach Britton was obtained to give the Yankees a super bullpen, their relievers have a 5.48 ERA (sixth worst in the majors) with an .820 OPS against. Is Greg Bird the first baseman of the present or future? Gleyber Torres has hit the rookie wall at the plate and Miguel Andujar in the field.

Will Aaron Judge and Gary Sanchez be back and productive by the Sept. 3-9 six-game trip to Oakland and Seattle that could allow the Yankees to cruise comfortably to the No. 1 wild-card seed or could threaten their ability to make the playoffs at all?

5. Astros (93.1/99.4/22.5): By losing four straight at home over the weekend to the Mariners to run their home losing streak to eight, the Astros revived Seattle and endangered their AL West hold (two up on the A’s, 4 1/2 on the Mariners through Monday). Lance McCullers is on the DL, and the rotation has slowed from its outrageous first-half production. Carlos Correa is back, but Jose Altuve and George Springer remain out. Could they have done more damage to their ecosystem than helped their pen by hypocritically bringing in Roberto Osuna while he was still serving a suspension for violating MLB’s domestic abuse protocols against what the organization had said previously was “zero tolerance” for having players who violated that decree? On Friday, Houston begins a six-game road trip through Seattle and Oakland.

6. Indians (100/100/13.7): It is hard to judge how good Cleveland is when it shares a division with four woeful clubs. Its bullpen has performed better with lefties Andrew Miller off the DL, Brad Hand from the Padres and (believe it or not) Oliver Perez after his release from a Yankees minor league deal. Can a team win it all with a deep rotation (though Trevor Bauer went to the DL Tuesday with a stress fracture in his fibula) and two great position players (Francisco Lindor and Jose Ramirez)?

7. Red Sox (95.2/100/15.5): How hard should they go after a historic win total? Those attending the 114-win Yankees reunion this weekend can tell how much more pressure it puts on a club in the postseason to validate that kind of regular season.

Boston will try to get closer Craig Kimbrel right and starter Eduardo Rodriguez healthy. Of the Super Seven, the Red Sox generally had the lowest win projection. Yet, they have been the most super of the group.
