Move over, 1964 Phillies. Make room there, 1978 Red Sox. Squeeze to the side, 1951 Dodgers.

The 2007 Mets are joining you. In fact, they’re eclipsing you.

The Mets completed the greatest late-season collapse in baseball history in fitting fashion yesterday, giving up seven runs in the top of the first inning and falling meekly to the Marlins, 8-1. The loss eliminated them from the wild-card race, and within five minutes of the end of the game at Shea Stadium they were out of the postseason entirely as the Phillies completed a 6-1 victory over the Nationals that gave Philadelphia an N.L. East championship that was tucked snugly in New York’s back pocket 18 days ago.

The Mets led the division by 7½ games with 17 to play on Sept. 12 and no team — not even other famous folders such as the ’64 Phils, ’78 Sox and ’51 Dodgers — ever squandered that big a lead over that span of time. The Mets did it by losing 12 of their last 17, capping their march into infamy with a 1-6 homestand against three sub-.500 teams (Washington, St. Louis and Florida) during the season’s final week.

One other playoff spot was up for grabs heading into yesterday’s final day of baseball’s regular season, and it’s still up for grabs today. The Rockies broke a 1-1 tie by scoring three runs in the bottom of the eighth inning, then held on for a 4-3 win over the Diamondbacks. That lifted them into a tie for the National League wild-card spot with the Padres, who could have won it outright with a victory at Milwaukee but instead were beaten by the Brewers, 11-6.

San Diego will play at Colorado tonight in a one-game playoff for the wild card, with the winner going on to face the Phillies in the National League Division Series. The Diamondbacks and Cubs will meet in the other series. The American League matchups — Red Sox/Angels and Yankees/Indians — were determined Friday.
