It’s the Bermuda Triangle of baseball.

The Colorado Rockies, Arizona Diamondbacks and Los Angeles Dodgers have put a death grip on the National League wild-card race.

It’s all over, thanks to the supremacy of the NL West.

Don’t believe me? Through Sunday, the Rockies (46-26), Dodgers (45-26) and Diamondbacks (44-26) had the three best records in the National League, and all happen to reside in the West.

While no team in the American League is further than 4 1/2 games out of a playoff berth, the Dodgers and D-backs have a nine-game lead over the Chicago Cubs in the NL wild-card race, and 12 games over everyone else.

It could be the first time since Major League Baseball implemented the two-team wild-card format in 2012 that three teams from the same division could all reach the playoffs with a .600 winning percentage. The NL Central came the closest in 2015 when the St. Louis Cardinals, Pittsburgh Pirates and Chicago…
